WhisperCal

A desktop-only Obsidian plugin that puts your calendar in a sidebar (Microsoft 365 or Google Calendar), creates templated meeting notes with one click, records meetings and links transcripts to notes, and drives an LLM-powered pipeline to tag speakers, research context, and summarize meetings.

Desktop only — works on macOS and Windows. Some features are macOS-only (see Platform Support below). Will not load on Obsidian mobile.

Project Status & Tested Configurations

WhisperCal is built and used daily by a single developer, so some integrations are far better exercised than others. Read these caveats before relying on a path that hasn't been heavily tested:

  • MacWhisper integration may be stale. Development started with MacWhisper as the recording source, but mid-project the recording flow was rewritten around a localhost Recording API (a fork of Tome). The Recording API path is the actively maintained one — MacWhisper code still ships and was working when last touched, but it has not been smoke-tested recently and may have regressed. If you depend on MacWhisper, please file issues; PRs welcome.
  • Google Calendar is loosely tested. The developer uses Microsoft 365, so Microsoft Graph is the well-trodden path. Google Calendar support is implemented and has been smoke-tested but does not get the daily exercise that the Microsoft path does. Edge cases (recurring events, tentative responses, secondary calendars, all-day events spanning timezones, etc.) are likely to surface bugs before they're caught in development.
  • Only Claude has been tested as the LLM CLI. The llmCli setting accepts any command that reads a prompt from stdin and writes the response to stdout, but only Anthropic's claude CLI has been used in practice. Other CLIs (e.g. codex, OpenAI-style wrappers) may need adjustments to flags, prompt format, or output parsing before they work. The "Per-prompt model selection" feature additionally assumes Claude model IDs and queries the Anthropic API to populate the model dropdown; with a non-Claude CLI those dropdowns will be empty and you'll need to type model IDs by hand.

Table of Contents


Features at a Glance

  • Calendar sidebar — Browse your Microsoft 365 or Google Calendar day by day inside Obsidian, with automatic refresh, offline caching, and conflict detection.
  • One-click meeting notes — Create a pre-filled note from any calendar event using a customizable template with wiki-linked attendees.
  • Dual recording sources — Link MacWhisper recordings by timestamp match, or record directly via a REST-based Recording API with a live timer on the card.
  • Automated recording — Optionally tie recording to the meeting's lifecycle: clicking a meeting's join link on its card auto-starts recording, and pressing Stop closes the meeting app (Teams, Zoom) to leave the call. See Automate Meeting Recording.
  • Transcript post-processing — embeddings-first — Known people are tagged by acoustic voiceprint (matched against your enrolled library), locally, before any LLM runs; unknowns are confirmed by ear in the modal. An optional LLM pass (enabled by setting a post-processing prompt) fixes transcription and diarization errors in the transcript itself and proposes names for speakers voiceprints didn't match. Review proposals with per-speaker excerpts and click-to-play before approving.
  • Acoustic voiceprints — When Tome exports per-speaker voice embeddings, applying speaker tags enrolls each confirmed person into Caches/Voiceprints/. Returning speakers then match automatically, the library self-improves as you tag, and a corrected false match self-heals. Optionally auto-tag recordings where every speaker is a high-confidence match — these silent auto-tags skip the modal but never write back to a library, guarding against voiceprint drift.
  • Teams meeting chat — When a recording finishes, the meeting's Teams chat is pulled into the note under a ## Meeting Chat heading — links, corrections, and side conversation the transcript never captured. Verbatim, LLM-free, authors linked to People notes, and re-pullable from the ⋯ menu to catch what gets posted after the call. See Teams Meeting Chat.
  • Meeting summarization — Run an LLM in the background to produce an executive summary, with a progress banner in the note editor.
  • Per-run custom instructions — The card's smart action button (and the matching ⋯ menu items) for speaker tagging and summarization open an instructions dialog where you can add one-off instructions for that LLM run (e.g., "focus on action items"); leave it empty to run normally.
  • Meeting export — Bundle a meeting's note, transcript, and source audio into a single .zip outside the vault (⋯ menu > Export meeting bundle), ready to email or hand to someone who doesn't use Obsidian.
  • Meeting import — Take a bundle someone sent you and file it into your own vault (calendar ⋯ menu > Import meeting bundle), so a meeting you never attended reads like one you recorded yourself.
  • Meeting merging — Select two or more meeting cards and merge their notes and transcripts into one, with speaker labels renumbered, durations summed, and the original parts archived. Built for back-to-back recordings of a single long meeting.
  • Meeting splitting — The inverse of merging: when one recording covers two unrelated meetings, place a marker in the transcript where the second one begins and split it into two meetings — each with its own note, transcript, attendees, and voiceprints — ready to tag and summarize independently.
  • Meeting research — Select vault notes as context and run an LLM to generate pre-meeting research, independent of the transcript pipeline. Recurring meetings can carry reusable prep in a per-series note that pre-fills the research modal.
  • People matching — Attendees and organizers are matched to notes in a People folder and rendered as [[wiki links]]. Unmatched organizers can be auto-created.
  • Per-prompt model selection — Choose a different Claude model for each LLM prompt (speaker tagging, summarization, research).

MacWhisper is a macOS-only app. On Windows, the MacWhisper option is hidden and the plugin defaults to the Recording API for transcript capture. LLM debug mode opens the LLM command in a visible terminal window on both platforms (Terminal.app on macOS, a console window on Windows).


Prerequisites

  • Obsidian 1.13.0 or later (desktop only — macOS or Windows)
  • A Microsoft 365 account with calendar access, or a Google account with Google Calendar
  • For Microsoft: an Azure AD app registration (see Microsoft 365 Setup)
  • For Google: a Google Cloud Console OAuth credential (see Google Calendar Setup)
  • MacWhisper (macOS only) or a Recording API-compatible app (optional — needed for transcript features; see Recording Sources)
  • An LLM CLI tool (optional — needed for speaker tagging, summarization, and research; default: Claude Code claude CLI)

Obsidian plugins

WhisperCal uses only Obsidian's native APIs, so no community plugin is required for it to run — the calendar sidebar, meeting notes, the full pipeline, and the speaker-tagging clip player all work out of the box. A few plugins make WhisperCal's outputs nicer to live with, but each is optional:

PluginWhat it addsDo you need it?
BRATOne-click install and automatic updates (see Installation)Recommended for installing — skip it if you install manually
Media ExtendedWaveform, scrubbing, and speed controls when a meeting recording is embedded in a note bodyOptional — Obsidian's native player already plays .m4a, and WhisperCal's own speaker-tag clip player is native, so nothing breaks without it
JSON ViewerPretty-prints .json files opened in the vaultOptional — only for eyeballing WhisperCal's data files: voiceprint libraries in Caches/Voiceprints/*.json and Tome's *.voiceprints.json sidecars
DataviewRenders a "related meetings" query inside People notesOptional — needed only if your People-note template includes such a query; WhisperCal emits no Dataview itself

None of these touch the core pipeline. MacWhisper (macOS only) and the Recording API app (Tome) are external apps, not Obsidian plugins — see Recording Sources.


Installation

Note: WhisperCal is not yet available in the Obsidian community plugin directory. Install using BRAT or manually from GitHub releases.

Using BRAT (recommended)

  1. Install the BRAT plugin from Community plugins.
  2. Open Settings > BRAT > Add Beta plugin.
  3. Enter dloomis/WhisperCal and click Add Plugin.
  4. Enable WhisperCal in Settings > Community plugins.

BRAT automatically downloads new releases and keeps the plugin up to date.

Manual Installation

  1. Download main.js, manifest.json, and styles.css from the latest release.
  2. Create a folder at <your-vault>/.obsidian/plugins/whisper-cal/.
  3. Copy the three files into that folder.
  4. Open Settings > Community plugins and enable WhisperCal.

Upgrading from 0.8.x (WhisperCore no longer required)

WhisperCal 0.8.x kept your calendar sign-in and LLM engine settings in a separate WhisperCore plugin. WhisperCal now holds them itself again, so new installs need only this one plugin.

If you are upgrading, update WhisperCal before you uninstall WhisperCore. On its first load, the new version copies your provider credentials, sign-in tokens, and LLM engine settings out of WhisperCore's data file (.obsidian/plugins/whispercore/data.json), so there is nothing to re-enter and no need to sign in again. It never changes WhisperCore's file. If that file can't be read on the first try (for example it is still syncing), WhisperCal shows a notice and retries the next time Obsidian starts; anything you set up in WhisperCal in the meantime is kept rather than overwritten. If you remove WhisperCore first, that file is gone and you will need to re-enter your provider credentials and sign in again.

Once WhisperCal shows your calendar, you can uninstall WhisperCore — unless you also use WhisperOrg, which still needs it for now.


Setup

Choosing a Calendar Provider

WhisperCal supports two calendar providers. In Settings > WhisperCal > Calendar, select your provider from the Calendar provider dropdown:

  • Microsoft 365 — Connects via Microsoft Graph API using OAuth2 Authorization Code with PKCE.
  • Google Calendar — Connects via Google Calendar API using OAuth2 Authorization Code with PKCE.

The rest of the settings UI adapts to show only the fields relevant to your chosen provider. You can switch providers at any time — each provider's auth tokens are stored separately, so switching back preserves your sign-in.

Microsoft 365 Setup

WhisperCal connects to your calendar through the Microsoft Graph API. You need to register an app in Azure AD:

  1. Go to the Azure Portal > Azure Active Directory > App registrations > New registration.
  2. Set a name (e.g., "WhisperCal").
  3. Under Supported account types, choose the option that matches your organization.
  4. Under Redirect URI, select Public client/native (mobile & desktop) and set the URI to http://localhost.
  5. Click Register.
  6. On the app's Overview page, copy the Application (client) ID. The Directory (tenant) ID is optional — leave it empty to auto-detect from your account at sign-in.
  7. Go to API permissions > Add a permission > Microsoft Graph > Delegated permissions.
  8. Add Calendars.Read, People.Read, User.ReadBasic.All, and offline_access. WhisperCal requests all of them at sign-in: the calendar scope reads your events, and the two people scopes back the people search (for example the Important organizers autocomplete). If you want Teams Meeting Chat, add Chat.Read as well.
  9. Click Grant admin consent (if required by your organization).

Then in WhisperCal settings:

  • Paste the Client ID into the corresponding field. Tenant ID is optional — leave it empty to auto-detect from your account at sign-in, or paste a specific tenant ID to restrict sign-in to one organization.
  • Select your Cloud instance (most users should leave this on "Public").

Google Calendar Setup

⚠️ Caveat: The developer uses Microsoft 365, so the Google Calendar path is loosely tested. Sign-in, basic event fetching, and people search work, but edge cases (recurring exceptions, secondary calendars, response statuses, timezone-spanning events) are likely to surface bugs. See Project Status & Tested Configurations.

WhisperCal connects to Google Calendar through the Google Calendar API. You need to create OAuth credentials in the Google Cloud Console:

  1. Go to the Google Cloud Console.
  2. Create a new project (or select an existing one).
  3. Navigate to APIs & Services > Library and enable the Google Calendar API and the People API.
  4. Go to APIs & Services > Credentials > Create credentials > OAuth client ID.
  5. Set the application type to Desktop app and give it a name (e.g., "WhisperCal").
  6. Click Create and copy the Client ID and Client secret.
  7. If your app will be used by more than 100 users, complete the OAuth consent screen verification. For personal use this is not required.

Then in WhisperCal settings:

  • Paste the Client ID and Client secret into the corresponding fields under "Google account".

Signing In

Both providers use an OAuth2 Authorization Code flow with PKCE. The experience is the same:

  1. Click Sign in in the WhisperCal settings panel (or in the calendar sidebar's inline sign-in banner).
  2. Your default browser opens to the provider's sign-in page.
  3. Sign in and grant WhisperCal access to your calendar.
  4. The browser redirects to a localhost page confirming success. You can close the tab and return to Obsidian.

If you don't complete sign-in within 5 minutes, the flow times out and you can try again.

For both providers, tokens are stored locally in the plugin's data.json file within your vault. Access tokens refresh automatically; you should rarely need to sign in again. To sign out, click Sign out in settings.

Cloud Instances (Microsoft)

If your organization uses a government or sovereign cloud, select the appropriate instance in settings:

The Calendar View

Open the calendar sidebar by clicking the calendar ribbon icon or running the "Open calendar view" command.

Navigation

  • Left / right chevron — Move one day backward or forward.
  • Date label — Click the date between the chevrons to open a date picker and jump straight to any day.
  • Today button — Jump to the current date (hidden when already viewing today).
  • Refresh button — Manually refresh calendar data from your calendar provider.
  • Settings gear — Opens WhisperCal settings directly from the calendar header.
  • ⋯ menu — Calendar-level actions, currently Import meeting bundle….
  • Sign in — When signed out, an inline banner appears at the top of the calendar with a sign-in button, so you don't need to visit settings to authenticate.

The calendar auto-refreshes on a configurable interval (default: every 5 minutes). At midnight, the view automatically advances to the new day.

Status Indicator

A small dot below the header shows connection status:

  • Green dot + "Updated X min ago" — Live data from your calendar provider.
  • Gray dot + "Cached X min ago" — Showing previously fetched data (offline or between refreshes).
  • Gray dot + "Offline" — No cached data available for this day.

Meeting Cards

Each calendar event is displayed as a two-column card:

  • Time gutter (left) — Start/end times, duration, "All day", or "Ad hoc" for unscheduled meetings. Below the time, an inline row of icons provides at-a-glance context (see Gutter Icons). Beneath that sit the card's two fixed controls: the capture button (Record / Re-record / Stop — Recording API source only) and the ⋯ menu button. While a job runs, a compact activity badge shows what's happening and on which model. A category color bar runs along the left edge and the gutter takes a wash of the same color (see Gutter Colors); meetings you haven't accepted get a dashed bar.
  • Content (right):
    • Subject — The meeting title. Clicking it opens the meeting note (creating it first if it doesn't exist yet; unscheduled cards prompt for a name). A dotted underline appears on hover.
    • Organizer row — Organizer name with People note link (if matched). The person icon reflects their personnel_type (see Personnel Type Icons).
    • Meta row — Location (clickable for online meeting URLs), total attendee count, RSVP breakdown (accepted in green, tentative in yellow, declined in red, no response in gray), and duration, separated by middle dots. Hover the attendee count or any RSVP icon to see the names in that group.
    • Status rail — Four labeled segments (Note · Transcript · Speakers · Summary) tracking pipeline progress. Each is clickable and acts on its stage (see The Status Rail).
    • Smart action button — One button showing the pipeline's next step after capture (Link recording / Review speakers / Tag speakers… / Summarize meeting…). There is no button while a job is running or once the pipeline is complete.

Cards are always shown in full — the rail labels and the action row don't depend on hovering. All-day events (if enabled in settings) appear at the top, followed by timed events sorted by start time.

The Card Actions Menu

The ⋯ button in the card's gutter — or right-clicking anywhere on the card (except links) — opens a menu of the card's secondary actions. The menu is always available, and its items adapt to the pipeline state:

ItemShown whenWhat it does
Open note / Create noteAlwaysOpens the meeting note, or creates it first if it doesn't exist (same as clicking the title)
Open transcriptA transcript is linkedOpens the transcript file (same as the transcript rail segment)
Review speaker candidatesCached speaker proposals await reviewOpens the confirmation modal (same as the Review speakers button)
Tag speakers…Transcript linked, speakers not yet taggedOpens the instructions dialog, then runs LLM speaker tagging
Edit speaker tagsSpeaker tags appliedRe-opens the confirmation modal pre-filled with the current assignments — no LLM re-run
Summarize meeting… / Regenerate summary…Speakers tagged / summary completeOpens the instructions dialog, then runs summarization
Research meeting…Always (LLM on)Opens the research modal — creates the meeting note first if needed; shows a disabled "Researching…" while a run is in progress
Split transcript…Transcript linked, meeting not yet summarized, nothing mid-runOpens the transcript in split mode to divide it into two meetings (see Splitting a Meeting)
Pull Teams meeting chatOnline meeting, note exists, Microsoft calendarRe-reads the meeting's Teams chat into the note (see Teams Meeting Chat)
Skip kanban processing / Unmark kanban reviewedA meeting note existsSets or clears the note's kanban-reviewed mark (see The Kanban Review Mark)
Export meeting bundle…A meeting note existsBundles the meeting's artifacts into a .zip outside the vault (see below)
Rename note…A meeting note existsRenames the note, optionally renaming its transcript, audio, and voiceprint sidecar with it; links are rewritten
Delete note…A meeting note exists, no live recordingConfirms, then moves the note (and, optionally, its related files) to the trash

Recording has no menu item: the gutter's capture button covers Record, Stop, and Re-record at every stage.

The everyday next step stays one click on the smart button; the menu keeps everything else reachable without growing the action row.

Exporting a Meeting Bundle

Export meeting bundle… (in the ⋯ menu) packages a meeting's artifacts into a single .zip outside your vault, ready to attach to an email:

  • The meeting note — which carries the summary and any research section
  • The linked transcript
  • The transcript's source audio (.m4a), when present

A system folder picker asks where to put the .zip (falling back to ~/Downloads if the picker is unavailable). The archive is named after the meeting note and, once written, revealed in Finder/Explorer. Inside, the files sit in a single flat folder named for the meeting, so the wiki links between them still resolve by basename if the folder is extracted and opened as an Obsidian vault.

Importing a Meeting Bundle

Import meeting bundle… — in the ⋯ menu in the calendar sidebar's header, next to Refresh and Settings — is the other end of export: it takes a bundle someone sent you and files it into your vault. It's meant for a meeting you weren't part of, so nothing has to exist locally beforehand.

The files cross over verbatim — a bundle is written by another WhisperCal vault, so its frontmatter already has the right shape and its links already point at each other:

  • The meeting note goes to your note folder and the transcript and audio to your transcript folder, all under the names the sender used.
  • The meeting lands as an ad-hoc meeting, since it has no event on your calendar. Its card shows up on the meeting's date, and you can summarize, re-tag speakers, export, rename, or delete it like any other.
  • The one field rewritten is calendar_provider, which the calendar filters cards on — without it a bundle from a Google vault would import invisibly into a Microsoft 365 one.

Nothing already in your vault is overwritten. If a name is taken — you already imported this bundle, say — the note, transcript, and audio all shift to a free suffix together (… 2), and the links between them are rewired to match.

All-Day Events

When "Show all-day events" is enabled in settings, all-day events appear at the top of the calendar as compact, read-only cards. They show the event subject and category color bar but have no action button — they are informational only.

Unscheduled Meetings

An "Unscheduled Meeting" card always appears at the top of the calendar view. Use it to create notes for ad-hoc meetings that aren't on your calendar. The subject is configurable in settings (default: "Unscheduled Meeting").

Unscheduled notes use the current timestamp as their meeting time and get a wider recording-matching window (720 minutes instead of the usual 15).

Merging Meetings

When one long meeting ends up as several back-to-back recordings (e.g., "Planning part 1", "Planning part 2"), you can merge the parts into a single meeting note and transcript:

  1. Hover a meeting card's time gutter — cards with an existing note show a merge checkbox.
  2. Check two or more cards. A merge bar appears in the header showing the selection count with Merge and Clear buttons.
  3. Click Merge. A confirmation modal lists the parts in chronological order with each one's pipeline state, and prompts for the merged meeting name. The default name strips trailing "part N" suffixes and picks the most common base title.

What merging does:

  • Builds one merged transcript with a ### Part N heading per recording (original timestamps and recording embeds preserved), a combined Context section, and the total duration summed across parts.
  • Renumbers raw "Speaker N" stubs so they stay unique across parts ("You" and already-tagged names pass through unchanged). Attendees, confirmed speakers, and tags are unioned.
  • Keeps the calendar-linked part (or the earliest part) as the merged note, renames it to the merged name, and appends the other parts' note bodies as ## Part — … sections so per-part summaries aren't lost.
  • Leaves the original part notes and transcripts in place — each part note just gains a merged_into backlink, which hides its calendar card in favor of the merged one.
  • Records every source MacWhisper session in macwhisper_session_ids and links the originals in merged_from frontmatter.
  • Sets pipeline_state: tagged if every part was already tagged, otherwise titled — so you can run Speakers and Summary on the merged transcript as usual.

Parts can be in any pipeline state — calendar-linked, ad hoc, tagged, or raw — and can be mixed freely in one merge.

Splitting a Meeting

The inverse of merging: sometimes one recording covers two meetings — a scheduled tag-up dovetails into an unrelated discussion that deserves its own note, tags, and summary. Split transcript… (in the card's ⋯ menu) divides the transcript into two meetings at a point you choose:

  1. Pick Split transcript… on the card. The transcript opens with a banner across the top of the editor.
  2. Click in the transcript where the second meeting begins and press Place marker — a --- ✂ SPLIT … ✂ --- line appears at the cursor. You can move it by placing again (or cutting and pasting the line). Cancel removes it and changes nothing.
  3. Press Split…. A confirmation modal shows where the cut lands — the split snaps forward to the next speaker line — with each half's start time, duration, and speaker-line count, and asks for the new meeting's title.

What splitting does:

  • Everything from the split point onward moves to a new transcript and a new meeting note, named and timestamped as if the second meeting had always been its own: the new meeting_start is the original start plus the split point's timestamp offset.
  • Attendees, confirmed speakers, and the voiceprint sidecar are filtered per half — each meeting lists only the people who actually speak in it. Applied speaker tags carry over; each half can then be tagged and summarized independently.
  • Both halves share the original audio file, and transcript timestamps stay recording-relative, so click-to-play keeps working in each. Deleting one half leaves the shared audio in place for the other.
  • The original meeting keeps its calendar link and is trimmed to end at the split time; the new meeting appears as its own card at the split time (a local card with a synthetic split- id, like a merged meeting). The two are cross-linked via split_from / split_into frontmatter.
  • The new files are fully created before the original transcript is touched, so an interrupted split never loses text.

Splitting is offered only before the meeting is summarized — an existing summary would describe both halves — and while no recording or LLM job is running on the card.

Active Event Highlighting

When viewing today's calendar:

  • Currently ongoing events (between start and end time) are highlighted.
  • If no event is ongoing, the next upcoming event is highlighted instead.

Conflict Detection

When multiple events overlap in time, they are grouped together and preceded by a banner showing the overlap window (e.g., "3 meetings overlap at 2:30 PM – 3:00 PM"). This makes scheduling conflicts immediately visible.

Gap Markers

Between non-overlapping event groups, a gap indicator shows how much free time you have (e.g., "45m" or "1h 15m").

Gutter Icons

Below the time and duration, the gutter displays a row of inline icons:

IconMeaning
☆ StarYou are the organizer of this meeting. Determined by comparing the event's organizer email against your calendar account email.
⛔ Octagon-alertThe organizer is in your important organizers list (configured in settings with people autocomplete from your calendar provider).
⊞ Grid-2x2The meeting has a category assigned (Outlook categories for Microsoft, color labels for Google). The icon color matches the category color. Hover for the category name tooltip.
Kanban boardThe meeting note carries a kanban-reviewed mark (see The Kanban Review Mark).

Gutter Colors

The gutter takes a light wash of the meeting's category color (Outlook categories for Microsoft, color labels for Google) — the same color as the category bar on the card's left edge — and its divider a stronger dose of the same hue. Uncategorized meetings keep a muted default.

The gutter does not show pipeline progress; the status rail reports that, segment by segment.

The Kanban Review Mark

A meeting note can carry a kanban-reviewed frontmatter key, meaning its action items have been triaged onto a kanban board. WhisperCal does not do that triage itself — the mark is written by separate vault automation — but it shows and toggles the mark:

  • A kanban icon appears in the gutter's icon row once the mark is present.
  • Skip kanban processing in the ⋯ menu stamps the mark by hand (with a "manually skipped" note), taking the meeting out of that automation's queue.
  • Unmark kanban reviewed clears the mark, whoever wrote it.

If you don't run such automation you can ignore this entirely.

The Activity Badge

While anything is happening on a meeting — an LLM job, voiceprint matching, transcript linking — a compact activity badge appears in the time gutter, level with the action row:

  • Line 1 — a one-word verb for the work in flight: Processing (transcript post-processing + speaker tagging), Summarizing, Researching, Matching (voiceprint), Transcribing, Linking, Waiting, Enriching.
  • Line 2 (LLM jobs only) — the model running the job, e.g. Opus 4.8 or Sonnet 5.

When the work finishes, the badge briefly shows the outcome — Linked, Tagged, Summarized, Researched, or a warning like Failed / Not ready — then clears. Hovering the badge shows the full status message as a tooltip. The badge replaces the older verbose status line under the rail.

Category Bar

The vertical bar on the left edge of the card indicates the event category color (Outlook categories for Microsoft, color labels for Google). When no category is assigned, it uses a subtle default.

The Status Rail

Under the meta rows, a four-segment rail tracks pipeline progress: Note · Transcript · Speakers · Summary. Each segment is a labeled, clickable bar:

  • Note — opens the meeting note, creating it first if it doesn't exist.
  • Transcript — opens the transcript.
  • Speakers — opens the speaker confirmation modal when candidates await review or tags are already applied (the same as Edit speaker tags); otherwise opens the transcript.
  • Summary — opens the meeting note.

Segment colors:

StateAppearance
PendingNeutral border color; disabled if its artifact doesn't exist yet.
DoneGreen fill (--text-success).
RunningAccent fill (--interactive-accent), pulsing (a background LLM job for that stage). A running research job pulses the Note segment.
Needs youWarning fill (--text-warning) — the pipeline is mid-flight and waiting on you: Speakers once a transcript is in (candidates to review or manual tagging), Summary once speakers are tagged.
RecordingRed fill (--text-error), pulsing — Transcript, while a live recording is running.

All segment colors are Obsidian semantic theme variables, so they follow your theme and light/dark mode. A stage that has just completed plays a brief fill animation, and finishing the whole pipeline plays one across the full rail.

Below the rail sits the smart action button — the pipeline's next step after capture, fully labeled: Link recording (MacWhisper source), Review speakers · N (accent-tinted, with a count of the speakers awaiting confirmation), Tag speakers…, or Summarize meeting…. While an LLM job runs there is no button — the activity badge and the pulsing segment say what's happening — and when the pipeline is complete there is none either.

Recording is deliberately separate: the capture button in the gutter (Recording API source) reads Record, then turns into a red Stop button with a live timer beneath it, and reads Re-record once a transcript is linked.

Non-Accepted Meeting Indicator

Meetings you haven't accepted (tentative, not responded, or declined) show a dashed category bar on the time gutter, alternating between the category color and the primary background color, making them visually distinct from accepted meetings.

Note-Open Highlighting

When you open a meeting note in any editor tab, the corresponding card in the calendar sidebar is highlighted with a light wash of your theme's accent color and scrolled into view. If the note belongs to a different day, the calendar automatically navigates to that day.

The same highlight applies to transcripts: opening a transcript file highlights its meeting card, and opening an unlinked transcript highlights its card in the Unlinked Recordings section.

Unlinked Recordings

A collapsible "Unlinked recordings" section appears at the bottom of the calendar view when there are recordings that haven't been linked to any note in your vault. This helps you catch recordings you forgot to process. The source depends on your recording setting — MacWhisper sessions or Recording API transcript files.

How it works:

  • MacWhisper: Scans the MacWhisper database for sessions within a configurable lookback window (default: 30 days). Skips recent recordings within a grace period (default: 48 hours).
  • Recording API: Scans the transcripts folder for transcript files not linked to any meeting note.
  • Cross-references against vault notes. Any recording not found linked to a note is shown as unlinked.

Linking an unlinked recording:

  1. Use the buttons on an unlinked recording card — View (first, since reviewing before linking is the common flow) opens the transcript directly, and Link starts the linking flow.
  2. WhisperCal checks the calendar cache for events near the recording's start time (using the same recording match window).
  3. If matching calendar events are found, a picker shows them along with a "Create unscheduled note" fallback. Events whose notes already have a recording linked are filtered out.
  4. If no matches are found, an unscheduled note is created directly, dated to the recording's actual start time.
  5. The recording is linked and a transcript is generated, just like the normal flow.

The section is collapsed by default and only appears when the count is greater than zero.


The Five-Stage Pipeline

Each meeting card tracks your progress through the meeting workflow with three separated controls: the title opens the note, the status rail shows each stage's state, and one smart action button offers the pipeline's next step (with the rest of the actions in the ⋯ menu). Recording has its own capture button in the gutter. The rail fills green as stages complete and greys out stages whose prerequisites aren't met.

Note  -->  Record/Transcript  -->  Speakers  -->  Summary
                                                     Research (independent)

Stage 1 — Note

Click the meeting title to create a meeting note from the calendar event.

  • A new Markdown file is created in your configured notes folder using your template.
  • The filename follows your configured pattern (default: YYYY-MM-DD - Subject.md).
  • Frontmatter is populated with meeting metadata (subject, date, time, location, attendees, etc.).
  • Attendees are matched against your People folder and rendered as [[wiki links]].
  • The organizer is shown with a People note link if matched.
  • The note opens in a new tab with the cursor placed after the # Notes heading.

Once the note exists, clicking the title opens it.

Stage 2 — Record / Transcript

How you capture depends on your configured recording source:

MacWhisper mode — The smart action button is labeled "Link recording". Click it to link an existing MacWhisper recording:

  • A picker modal shows MacWhisper recordings that started near the meeting time.
  • Select a recording, and WhisperCal writes the session ID to frontmatter, sets the recording title in MacWhisper, waits for transcription, creates a transcript file, and links everything together.

Recording API mode — The capture button in the card's gutter (a microphone icon) starts a live recording:

  • The recording starts via the configured API. The button turns into a red Stop button with a live elapsed timer beneath it, and the Transcript rail segment pulses red.
  • Click Stop to end the recording. WhisperCal polls for transcription completion, then links the transcript file to the meeting note. (The button returns to Record immediately — recording again during transcription is allowed.)

Once the transcript exists, open it from the Transcript rail segment (or Open transcript in the ⋯ menu). To capture a fresh take, click the capture button again — it now reads Re-record and asks for confirmation first (see Re-Recording).

Stage 3 — Speakers

Once a transcript exists, the smart action button becomes Tag speakers… — click it to run LLM speaker tagging in the background. (The same action is in the ⋯ menu. Once tags are applied, the menu offers Edit speaker tags instead — see Reviewing or Editing Tags Later.)

  • The button opens an instructions dialog — leave it empty and hit Run for a normal run, or add one-off hints. Single-mic recordings get a tailored prompt asking who's who.
  • The LLM reads your post-processing prompt and the transcript, fixes transcription and diarization errors in place (confirmed voiceprint matches are passed in as fixed anchors), then outputs proposed identities for the remaining speakers.
  • A confirmation modal appears inside Obsidian showing each speaker with the LLM's proposed name, confidence level, evidence, and transcript excerpts.
  • Review the proposals, edit names as needed, and click Apply to commit.
  • WhisperCal replaces speaker labels throughout the transcript and sets pipeline_state: tagged.

While the LLM is running there is no smart button: the gutter's activity badge names the job and its model, the Speakers rail segment pulses, and the transcript stays openable from the rail. If you dismiss the confirmation modal without applying, the proposals stay cached and the button becomes an accent-tinted "Review speakers · N" (N = speakers awaiting confirmation) with the Speakers segment turning warning-colored — clicking it resumes the review directly. Once tags are applied, the button advances to Summarize and the ⋯ menu offers Edit speaker tags.

Automatic mode: When the "Automatic mode" setting is on, WhisperCal runs this LLM step automatically in the background as soon as a transcript is linked to its meeting note — no clicks needed. The run stops after caching the proposals: tags are not applied without your review (unless you also enable auto-tagging for confident matches — see below). The smart button becomes Review speakers · N when candidates are ready; click it to review and apply as usual, after which summarization starts automatically. Single-mic recordings (voice memos, single-speaker diarization) are skipped since they benefit from per-run hints. On startup, a catch-up scan also auto-tags eligible transcripts created within a configurable window (default 48 hours).

Skip the modal for confident matches: Turn on "Auto-tag when all speakers match" to let WhisperCal apply tags without the confirmation modal — but only when every speaker in a recording is a voiceprint match at or above the "Auto-tag confidence floor" (default 0.80, deliberately high). A single unmatched or below-floor speaker falls through to the normal review — with one exception: diarizers often emit a junk speaker for crosstalk or stray utterances that never matches anything and you'd always leave blank anyway. The "Ignore minor speakers" setting (default 0.05) lets an unmatched speaker holding at most that share of the transcript's lines pass the gate untagged instead of blocking it; set it to 0 to require every speaker to match. Crucially, a silent auto-tag never enrolls or corrects any voiceprint library — only confirming a recording in the modal updates your libraries. This is the drift guard: it stops an unattended run from gradually teaching a person's voiceprint a misattributed or noisy centroid (cross-talk, stray utterances). The toggle works together with Automatic mode to decide the trigger:

  • Automatic mode off — the background tagger doesn't run; clicking the Review speakers button applies the matches and skips the modal (when all speakers clear the floor), otherwise the modal opens as usual.
  • Automatic mode on — the background run itself applies the matches with no click at all. The card briefly shows "Auto-tagging speakers by voiceprint…", then "N speaker(s) auto-tagged by voiceprint", then summarization starts. If not all speakers clear the floor, it falls back to caching candidates and turning the smart button into Review speakers for review.

Stage 4 — Summary

Once speakers are tagged, the smart action button becomes Summarize meeting… — click it to run LLM summarization in the background. (The same action is in the ⋯ menu.)

  • Clicking it opens a small instructions dialog — leave it empty and hit Run for a normal run, or type one-off instructions (e.g., "focus on the budget discussion").
  • While running, the activity badge reads Summarizing, the Summary rail segment pulses, and a "Summarizing…" banner appears at the top of the meeting note editor.
  • The LLM reads your summarizer prompt along with the meeting note and transcript, then writes the summary.
  • When finished, the plugin sets pipeline_state: summarized and the banner disappears.

Once the summary is complete, the menu item becomes Regenerate summary…, with the same optional instructions dialog.

Stage 5 — Research

Choose "Research meeting…" from the card's ⋯ menu to run LLM-powered meeting research. This stage is independent of the transcript pipeline — you can run it anytime, even before a recording exists (the meeting note is created first if it doesn't exist yet).

  • For a recurring meeting with a series note, the modal opens clean: a tag links to the series note whose prompt and default context notes are already pulled in, and you just click Research.
  • For everything else, expand "Add context notes or customize the prompt" to search and select vault notes as context (project plans, policies, prior meeting notes, etc.), add instructions, or override the prompt entirely.
  • The LLM reads your research prompt along with the selected notes and meeting context, then writes its findings into the meeting note.
  • When complete, the plugin sets research_state: research-done in the meeting note's frontmatter (the context notes you selected are recorded in research_notes). The menu item stays available to re-run research.

This is useful for pre-meeting preparation or post-meeting fact-checking against organizational documents.

Pipeline State Tracking

Pipeline state is stored in frontmatter as pipeline_state with these values:

ValueMeaning
titledTranscript created, ready for speaker tagging
taggedSpeakers identified, ready for summarization
summarizedSummary complete, pipeline finished

The state lives on the transcript file as its source of truth. WhisperCal automatically mirrors it to the meeting note's frontmatter whenever the transcript changes, so both files stay in sync.


Teams Meeting Chat

What gets typed into the Teams chat during a call — the link someone pastes, the correction nobody says out loud, the "+1" that settles a decision — never reaches the transcript. WhisperCal pulls that chat into the meeting note under a ## Meeting Chat heading once the recording's transcript is linked.

The log is verbatim and LLM-free: each message shows its author, local time, and body, with attachments as links and an (edited) marker where Teams reports one. Authors resolve to [[People note]] links when a matching note exists, so meeting chat joins the same backlink graph as invitees and confirmed speakers. Teams system messages ("X joined the meeting", "recording started") and deleted messages are dropped.

Enable it in Settings > WhisperCal > Recording > Pull Teams meeting chat (on by default). Microsoft calendars only.

Granting the permission

Reading chat needs the delegated Chat.Read Graph scope, which WhisperCal requests as part of its Microsoft sign-in. Two one-time steps:

  1. In the Azure portal, open your app registration → API permissions → Add a permission → Microsoft Graph → Delegated permissions → Chat.Read, then grant consent.
  2. In WhisperCal's settings (Calendar page), sign out and sign back in to Microsoft. WhisperCal sends its full scope set on every token refresh, so an existing session keeps refreshing against the old consent until it is re-established. (If your tenant grants admin consent for Chat.Read, the next refresh picks it up silently and you can skip this step — but signing out and back in is the reliable path either way.)

Until both are done, the automatic pull stays quiet and the card shows "Meeting chat unavailable — check the Chat.Read permission" after a recording; the manual pull explains the same thing in a notice.

Which messages land in the note

Only the chat from during the meeting — 5 minutes either side of it, to catch a "joining now" a minute early and a reply that lands just after someone hangs up.

The end of that window is whichever is later, the scheduled end or how long the recording actually ran (read from the transcript's duration). A meeting that goes 25 minutes over keeps chatting for those 25 minutes, and the scheduled end would cut the log off mid-conversation.

The window matters more than it looks, for two reasons. A recurring series shares one chat thread across every occurrence — the thread id is identical week to week — so an unwindowed pull would drop the entire series history into every occurrence's note. And the thread stays live all day after the call; everything posted to it later is a different conversation that happens to share an address.

The trade-off: messages posted well after the meeting never reach the note, including on a re-pull, which applies the same window. If you want a wider net, raise GRACE_MS in src/services/MeetingChat.ts.

Re-pulling

Pull Teams meeting chat in the card's ⋯ menu (or the Pull Teams meeting chat command with the note open) re-reads the thread and rewrites the section in place, so re-pulling is safe and repeatable. A re-pull that finds nothing leaves an existing section untouched rather than emptying it.

Re-pulling uses the same meeting window, so it isn't a way to collect post-meeting chatter — it's for filling in a note whose automatic pull was skipped, or one written before the meeting finished.

Two things worth knowing:

  • Notes created before this feature existed have no meeting_join_url to read, so WhisperCal falls back to re-fetching the event from Graph — which only works while the meeting is still on your calendar. New notes stamp the URL and keep working indefinitely.
  • Summarization edits the meeting note, and the chat section sits in that note. If a summarizer prompt rewrites the note wholesale it can disturb the section — re-pull to restore it.

Meeting Note Templates

Template Setup

WhisperCal uses a template file to control the body content of meeting notes. All frontmatter is auto-injected by the plugin from calendar data — you never need to put frontmatter keys in your template.

  1. Copy samples/WhisperCal Meeting Template.md from the plugin's GitHub repo into your vault (e.g., Templates/WhisperCal Meeting.md).
  2. Edit the body to your liking.
  3. Set the "Note template" path in WhisperCal settings.

If no template is configured, WhisperCal shows a notice and won't create notes.

Template Variables

Use {{variableName}} placeholders in your template body. All available variables:

Reserved Frontmatter Keys

The following keys are auto-injected by the plugin when creating a note. Do not add them to your template — they are managed programmatically:

KeyPurpose
meeting_subjectDisplay title in the calendar view; passed to transcript
meeting_dateCalendar navigation and recording time matching
meeting_startRecording time matching
meeting_endMeeting end time
meeting_locationMeeting location
meeting_inviteesAttendee list; passed to transcript creation
meeting_organizerMeeting organizer as wiki link
meeting_accepted / meeting_tentative / meeting_declined / meeting_no_responseEach invitee's RSVP, as wiki-link lists (same names as meeting_invitees); every invitee is in exactly one. Re-synced from the calendar on each refresh (see RSVP Tracking)
tagsUsed to distinguish meeting notes from transcript files
calendar_event_idIdentifies this file as a WhisperCal meeting note
meeting_join_urlOnline meetings only; carries the Teams chat thread id (see Teams Meeting Chat)
note_createdFallback timestamp for unscheduled notes
is_recurringPassed to transcript creation
macwhisper_session_idLinks a MacWhisper recording to the note
macwhisper_session_idsAll source session IDs on a merged note (see Merging Meetings)
session_guidCorrelation id tying the note to its Recording API session and the resulting transcript
meeting_series_idRecurring-series id; matches an occurrence to its series note
merged_fromLinks to the original parts on a merged note

split_offset_secondsOn the second half of a split: where it begins in the shared recording
research_stateSet to research-done when a research run completes
research_notesContext notes selected for research
kanban-reviewedExternal triage mark; WhisperCal only shows and toggles it (see The Kanban Review Mark)
transcriptBacklink to the transcript file
pipeline_stateWorkflow state; mirrored from transcript automatically

RSVP Tracking

Each invitee's response to the invite is recorded per person in four list properties, so it can be reported on across meetings:

meeting_accepted:
  - "[[Jane Smith]]"
meeting_tentative: []
meeting_declined:
  - "[[Bob Jones]]"
meeting_no_response:
  - "[[Ann Lee]]"

The lists are written when the note is created and kept up to date whenever the calendar view refreshes a day that has the meeting (a note is only rewritten when a response actually changed). Notes created before this existed pick the lists up the first time their day is viewed. The organizer is recorded in meeting_organizer, and appears in meeting_accepted only when the calendar lists them as an attendee.

For example, a Dataview table of every meeting someone declined:

TABLE meeting_date
WHERE contains(meeting_declined, [[Bob Jones]])
SORT meeting_date DESC

Recording Sources

WhisperCal supports two recording sources, configurable in Settings > WhisperCal > Recording > Source:

MacWhisper

⚠️ Caveat: MacWhisper was the original recording source but the developer has since switched to the Recording API path (Tome fork). The MacWhisper code still ships and was working when last touched, but it is not exercised daily and may have regressed. See Project Status & Tested Configurations.

The default source. WhisperCal reads directly from MacWhisper's local SQLite database to match recordings to meetings and extract transcripts. It does not modify your audio files.

Requirements:

  • MacWhisper must be installed (database path: ~/Library/Application Support/MacWhisper/Database/main.sqlite).
  • Recordings must be transcribed in MacWhisper before a transcript file can be created. WhisperCal will wait up to ~3 minutes for transcription to complete.

How recording matching works: When you click the Link recording button, WhisperCal queries the MacWhisper database for sessions whose recording start time falls within a configurable window of the meeting's scheduled start time.

  • Default window: 15 minutes before or after the meeting start.
  • Unscheduled meetings: 720-minute window (12 hours).
  • Recording start time is determined from the filesystem birthtime of the track-0 audio file, which is more accurate than MacWhisper's database timestamps.

If multiple recordings match, a picker modal lets you choose. The picker shows the recording title, date, time, and duration for each match.

Transcript file format: Transcript files are created in your configured transcripts folder with the naming pattern <Note Name> - Transcript.md. They contain:

  • Frontmatter: Recording date, tags: [transcript], macwhisper_session_id, duration, meeting_note backlink, speaker metadata, meeting context fields, and pipeline_state: titled.
  • Body: AI Summary (if MacWhisper generated one) as a blockquote, followed by the Full Transcript section. Diarized recordings show speaker-grouped lines with timestamps (**Jane Smith** [00:01:23]); non-diarized recordings show timestamped lines without speaker labels.

Linking flow: Match → Select → Title → Link session ID to frontmatter → Wait for transcription → Create transcript file → Backlink to meeting note.

Recording API

An alternative source that records meetings directly via a REST API. The Record button on meeting cards starts and stops recordings without leaving Obsidian. Any app that implements the required endpoints on localhost will work (e.g., Tome fork with REST API support — upstream Tome does not support REST API as of this writing).

Requirements:

  • A recording application running a compatible REST API on localhost.
  • The API must implement: GET /health, POST /start, POST /stop, GET /status.

API auto-discovery: If the Recording API base URL is left empty in settings, WhisperCal looks for a port file at ~/Library/Application Support/Tome/api-port (macOS) or %APPDATA%\Tome\api-port (Windows) and constructs the URL automatically. Apps that write a port number to this path will be detected without any configuration.

Recording flow:

  1. Click the capture button in the card's gutter — WhisperCal checks the API health, then sends a start request with the meeting subject and attendees.
  2. The button turns into a red Stop button with a live elapsed timer beneath it, and the Transcript rail segment pulses red.
  3. Click Stop — WhisperCal polls /status every 3 seconds until transcription is complete (up to 5 minutes).
  4. The transcript file is located in the vault's transcripts folder, enriched with pipeline frontmatter (meeting subject, invitees, date, organizer, location), and linked to the meeting note.

Automate Meeting Recording

Enable Automate meeting recording (Recording API source only) to tie the recording to the meeting's lifecycle so you don't have to touch the card:

  • Join → record. Clicking a meeting's join link on its calendar card launches the meeting app (Teams, Zoom, etc.) and automatically starts recording once the launch succeeds. If the recording service is already mid-recording, WhisperCal still confirms before starting a new one.
  • Stop → leave. When you then press Stop on that card, WhisperCal closes the meeting app it launched, disconnecting you from the call. It quits the whole app (there is no portable way to "leave the meeting" without it), so this only fires for calls WhisperCal launched for you — and only when you stop the recording from WhisperCal. If the call instead ends in the meeting app itself, nothing is force-closed.

The app is terminated with the platform's own process tools (killall on macOS, taskkill on Windows) rather than app scripting, so the behavior is portable across platforms. Recordings you start manually with the Record button never auto-close anything.

Re-Recording

If a meeting already has a linked transcript, the capture button in the card's gutter reads Re-record (Recording API source only). Clicking it shows a confirmation modal with options to View the existing transcript or Re-record. Re-recording clears the transcript link, pipeline state, and any speaker tags or summary.


People Matching

WhisperCal can match meeting attendees to notes in a People folder in your vault, rendering them as [[wiki links]] in meeting notes and providing context for LLM prompts.

Setup

  1. Create a folder in your vault for people notes (e.g., People/).
  2. Set the "People folder" path in WhisperCal settings.
  3. Each person note should have frontmatter with identifying information.

Matching Fields

WhisperCal matches attendees by checking these frontmatter fields in People notes:

Email fields (matched against the attendee's email address, case-insensitive):

  • company_email
  • personal_email
  • sipr_email
  • nipr_email
  • preferred_email

Name field (matched against the attendee's display name, case-insensitive):

  • full_name
  • Note filename (e.g., Alex Johnson.md matches "Alex Johnson")
  • nickname + last name from full_name (e.g., nickname "Alex" + full_name "Alexander Johnson" matches "Alex Johnson")

Exchange/DoD display names in "LAST, FIRST RANK ORG" format are automatically normalized before matching. Email-derived names with trailing digits (e.g., "alex.johnson.2@example.com") are also handled.

Email matching is tried first; if no email match is found, name matching is attempted. Matched attendees appear as [[Note Name]] wiki links in the template output. Unmatched attendees appear as plain text names.

Personnel Type Icons

When a matched organizer is displayed on a meeting card, WhisperCal replaces the default person icon with one that reflects their personnel_type frontmatter field:

personnel_typeIconDescription
MilitaryShield-halfMilitary personnel
CivilianLandmarkGovernment civilian
ContractorBriefcaseContractor
FFRDCFlaskFederally funded research and development center
SETAMicroscopeSystems engineering and technical assistance
Foreign NationalGlobeForeign national / coalition partner
C-SuiteCrownExecutive leadership
(empty or missing)UserDefault person icon

The field is case-insensitive. If personnel_type is not present in the frontmatter, the default person icon is used — no configuration is required for vaults that don't use this field.

Auto-Created People Notes

WhisperCal can automatically create People notes for meeting organizers who don't have a matching note in your vault. When the calendar view refreshes, it scans organizers and silently creates notes for ones that look like real people (filtering out team calendars, room resources, and system accounts).

Auto-created notes include frontmatter with full_name, nickname, organization (derived from email domain), and personnel type. The body comes from your People-note template — so if that template contains a Dataview "related meetings" query, the new note will too (which needs the Dataview plugin to render).

Example People Note

---
full_name: Jane Smith
company_email: jane.smith@example.com
personnel_type: Civilian
---

# Jane Smith

Role: Engineering Manager

LLM Integration

⚠️ Caveat: Only Anthropic's claude CLI has been tested. The plugin spawns whatever command is in the CLI command setting and pipes the prompt over stdin, so other CLIs (codex, OpenAI-style wrappers, etc.) may work — but flag handling, prompt format, and output parsing have not been validated against them. Per-prompt model dropdowns are also Claude-specific (they query the Anthropic API to enumerate models); with a non-Claude CLI those will be empty and you'll need to type model IDs manually. See Project Status & Tested Configurations.

WhisperCal invokes an external LLM CLI tool as a background process to tag speakers in transcripts, summarize meetings, and run meeting research. The LLM runs headlessly inside Obsidian — no terminal window is required. Progress and errors are reported via Obsidian notices.

Enable LLM features: LLM features are disabled by default. Toggle "Enable LLM features" in settings. On first enable, a consent modal explains that transcripts and note content may be sent to a cloud LLM provider, and asks you to confirm.

Included Prompts

The plugin ships with ready-to-use prompt files. On load it installs the post-processing, summarizer, and research prompts into your vault's Prompts/ folder if they aren't already there (it never overwrites an existing file). The repo's prompts/ directory holds the bundled copies; the samples/ directory holds copies for manual installation, alongside the meeting note template. They work out of the box as defaults — use them as-is, or copy them into your vault and customize them to fit your workflow.

Each prompt can run on its own model (see Per-Prompt Model Selection) and at its own reasoning effort. Set effort in that prompt's Additional flags setting, e.g. --effort medium — the claude CLI accepts low, medium, high, xhigh, and max. Recommendations:

Prompt fileWhat it doesRecommended modelRecommended effort
Transcript Post-Processing Prompt.mdFixes transcription and diarization errors in the transcript in place and proposes identities for the speakers voiceprints didn't match. Runs on every recording, so latency matters.Sonnetmedium
Meeting Transcript Summarizer Prompt.mdWrites the structured summary (decisions, action items, discussion points) into the meeting note.Sonnet — step up to Opus if downstream automation consumes the summaries and quality outweighs speedmedium
Meeting Research Prompt.mdPre-meeting research: synthesizes selected context notes and meeting metadata into findings in the meeting note. The most synthesis-heavy prompt of the set.Opushigh
Meeting Series Research Prompt.mdLighter research variant for recurring meetings driven by a series note. Not installed automatically and not in samples/ — copy it from the repo's prompts/ folder and point the Research prompt setting at it if you want it.Sonnetmedium
Speaker Auto-Tag Prompt.mdLegacy speaker-tagging prompt, superseded by Transcript Post-Processing. Kept for reference only.——

The reasoning behind the recommendations: post-processing and summarization are high-volume, well-scoped tasks that are comfortably within Sonnet's range, and they sit in the critical path of every recording — a smaller model returns minutes sooner at no practical quality cost. Going below Sonnet is not recommended for post-processing, where verbatim edit fidelity is the whole job. Research runs are infrequent, user-triggered, and synthesis-heavy, which is exactly where a larger model at higher effort earns its extra latency. A prompt with no model selected uses the CLI's default model, and with no --effort flag the CLI's default effort.

Speaker Tagging

WhisperCal is embeddings-first: when a recording has Tome voiceprints, known people are tagged acoustically before any LLM runs (each speaker's centroid is matched against the enrolled libraries in Caches/Voiceprints/, and confident hits are pre-filled as CERTAIN). Applying the tags enrolls each confirmed speaker, so the library self-improves; overriding a match self-heals the wrongly-matched library. How strict matching is can be tuned with the Voiceprint match floor setting.

Auto-tagging confident recordings (optional). By default every recording is reviewed in the confirmation modal. "Auto-tag when all speakers match" skips the modal when every speaker is a high-confidence voiceprint match; such silent auto-tags never enroll or correct a library, so the self-improving and self-healing behavior above only happens when you confirm in the modal. The full rules — the confidence floor, the minor-speaker exemption, and how it combines with Automatic mode — are in Stage 3 — Speakers.

Voiceprint libraries stay aligned 1:1 with your People notes: a confirmed name (whether proposed by voiceprint, the LLM, or typed by you) is canonicalized to its People-note basename before enrolling — so a library always maps to a real person note, the same target confirmed_speakers wikilinks resolve to. If you enroll someone who has no People note yet, a Notice nudges you to create one. (Email-derived name variants help here: a note emailed douglas.sperber@… still matches the LLM's formal "Douglas Sperber" even when its basename is "Doug Sperber".)

The optional transcript post-processing LLM pass runs whenever LLM features are on and a post-processing prompt is set (the prompt path is the on/off switch). In one pass it fixes the transcript in place — correcting transcription errors and diarization mistakes (mis-attributed lines, echo/overlap duplicates) — and proposes identities only for the speakers voiceprints didn't match (the confident voiceprint hits are passed in as fixed CERTAIN anchors). Word replacements run first as the only deterministic, non-LLM fix. Leave the prompt path empty to stay fully LLM-free: known people are still matched by voiceprint and unknowns confirmed by ear in the modal, and no transcript leaves your machine.

Prerequisite: A transcript file must exist (Stage 2 complete, pipeline_state: titled).

Setup:

  1. The plugin installs Prompts/Transcript Post-Processing Prompt.md into your vault automatically — customize it if needed. (To install it by hand, copy samples/Transcript Post-Processing Prompt.md from the plugin's GitHub repo into your vault.)
  2. Set the "Transcript post-processing" prompt path in WhisperCal settings (leave it empty to disable the LLM pass).
  3. Set the "Microphone user" field to your full name as it appears in meetings.

Upgrading? If your speaker-tagging prompt was still set to the previous default (Prompts/Speaker Auto-Tag Prompt.md), WhisperCal repoints it to the new Prompts/Transcript Post-Processing Prompt.md automatically on load. A custom prompt path is left untouched.

Usage:

  1. Click the Tag speakers… smart button (or choose it from the card's ⋯ menu), or run the "Tag speakers in transcript" command. Either opens an instructions dialog — leave it empty and hit Run for a normal run, or enter one-off custom instructions (e.g., "the unidentified speaker with an accent is probably Priya") before the LLM starts.
  2. The activity badge reads Processing and the Speakers rail segment pulses while the LLM runs in the background.
  3. When the LLM finishes, a speaker confirmation modal appears inside Obsidian.
  4. Review the proposed mappings, edit any names, and click Apply.
  5. WhisperCal replaces speaker labels in the transcript body and sets pipeline_state: tagged.

The confirmation modal shows each speaker from the transcript with:

  • The original stub name (e.g., "Speaker 1") and how many transcript lines they have.
  • A name dropdown pre-filled with the LLM's proposed name. Focus the field or click its caret to pick from the meeting's invitees (the transcript/note meeting_invitees), which appear first and are tagged invitee. You can still type a one-off name to match anyone in your People folder, or type a new name and choose "+ Create note" to make a person note on the fly.
  • A confidence badge (CERTAIN, HIGH, or LOW) and the LLM's evidence for its guess.
  • Speakers appear in the order they first speak in the transcript.

You can clear a name field to leave that speaker untagged. Click Cancel to discard all changes.

Per-Speaker Transcript Excerpts

Each speaker row in the confirmation modal has an expandable excerpt panel. Click the chevron toggle next to a speaker to see their actual transcript lines — timestamps and spoken text. This lets you read each speaker's words in context, making it easier to confirm or correct the LLM's identification without leaving the modal.

Click-to-Play Audio

When the transcript has a linked recording, the confirmation modal becomes a listening tool — text alone often isn't enough to tell who a generic "Speaker N" is, especially when their first lines are short ("Hm.", "Okay.").

  • A compact audio player appears at the top of the modal, loaded with the meeting recording.
  • Every timestamp in a speaker's excerpt panel is a click-to-play control: click it to play just that snippet — playback starts at the line and stops automatically at the next speaker's timestamp. Click a later line for the same speaker to hear a clearer sample. Pause and scrub freely with the player's own controls.
  • The "Speaker clip length (seconds)" setting caps how long each snippet plays. The default is 5, a fixed five-second clip (never bleeding past the next speaker); set it to 0 to play the whole snippet.

The recording is discovered automatically from the transcript's recording frontmatter key (a wiki link to the audio file, e.g. recording: "[[My Meeting.m4a]]"). The Recording API source writes this link when it saves the meeting audio into the vault. Timestamps are read straight from the transcript body, so no conversion or extra setup is needed. If a transcript has no linked recording, the modal behaves exactly as before — excerpts with plain-text timestamps and no player.

Required LLM Output Format

The plugin injects the expected output format into the LLM's trigger string at invocation time — your prompt file does not need to specify the format. The LLM's stdout must contain a fenced JSON code block with a speakers array:

```json
{
  "speakers": [
    {
      "index": 0,
      "original_name": "Microphone",
      "proposed_name": "Jane Smith",
      "confidence": "CERTAIN",
      "evidence": "microphone user"
    },
    {
      "index": 1,
      "original_name": "Speaker 1",
      "proposed_name": "Bob Lee",
      "confidence": "HIGH",
      "evidence": "introduced himself at 00:02:15"
    },
    {
      "index": 2,
      "original_name": "Speaker 2",
      "proposed_name": null,
      "confidence": null,
      "evidence": "no matching attendee"
    }
  ]
}
```
FieldDescription
indexZero-based index matching the order of speakers in the transcript's frontmatter speakers array. 0 = Microphone, N = Speaker N.
original_nameThe stub name from the transcript (e.g., "Microphone", "Speaker 1"). Must match the frontmatter speaker name exactly.
proposed_nameThe real name the LLM believes this speaker is. Use null if the LLM cannot determine the identity.
confidenceOne of "CERTAIN", "HIGH", or "LOW". Use null for unresolved speakers.
evidenceFree-text explanation of why the LLM made this identification (e.g., "microphone user", "introduced themselves at 00:05:12").

Important notes:

  • The parser extracts the first fenced ```json block from the LLM's stdout. Everything outside the block is ignored, so the LLM can include reasoning or other output around it.
  • If no JSON block is found, the parser falls back to the legacy Proposed Mapping: text format for backward compatibility.
  • If parsing fails entirely or the LLM returns empty output, WhisperCal falls back to showing the transcript's frontmatter speakers without AI suggestions. The user can still manually type names in the modal.

What Happens When You Apply

When you click Apply in the modal, WhisperCal:

  1. Updates each speaker entry in the transcript's frontmatter speakers array — sets name to the confirmed name, saves the original as original_name, and records confidence and evidence.
  2. Adds a confirmed_speakers frontmatter key with wiki links to all confirmed names (e.g., ["[[Jane Smith]]", "[[Bob Lee]]"]).
  3. Sets pipeline_state: tagged in the transcript frontmatter (and mirrors it to the meeting note).
  4. Replaces all occurrences of **Original Name** with **Confirmed Name** in the transcript body text.
  5. Applies word replacements from the configured replacement file (see Word Replacements below).

Reviewing or Editing Tags Later

Once a transcript is tagged, "Edit speaker tags" in the card's ⋯ menu re-opens the confirmation modal pre-filled with the current assignments — no LLM re-runs. Correct a name and click Apply to re-label the transcript body and update the tags. The names you already confirmed are kept as the starting point — a fresh voiceprint match won't silently overwrite them — and applying a correction reconciles the voiceprint libraries, so a fixed name teaches the library for next time.

Word Replacements

WhisperCal can fix common transcription errors automatically using a word replacement file — a simple list of search/replace pairs, one per line.

Setup:

  1. Create a markdown file in your vault (default path: Prompts/Word Replacements.md).
  2. Add one replacement per line in search,replace format. Lines starting with # are comments.
# Fix common transcription errors
Nipper,NIPR
Kariosoft,Carahsoft
Shine Mountain,Cheyenne Mountain
  1. Set the "Word replacement file" path in WhisperCal settings, or use the default. Click Open next to the setting to create and edit the file.

How it works:

  • Replacements are case-sensitive and use word boundaries to avoid partial matches (e.g., ash → ASH won't affect "crash").
  • Longer search terms are matched first, so Shine Mountain matches before Shine would.
  • Frontmatter is preserved — only the note body is modified.
  • All word-bounded terms are combined into a single regex pass for efficiency, even with 100+ rules.

When replacements run:

  • Automatically during transcript post-processing — word replacements run first (before the LLM cleanup pass), and again when you click Apply in the speaker tag modal.
  • Manually on any note — use the replace-all icon (⇄) in the note toolbar or the "Run word replacements" command from the command palette. A confirmation modal lets you review the replacement list before running.

Summarization

Prerequisite: Speakers must be tagged (Stage 3 complete, pipeline_state: tagged).

Setup:

  1. The plugin installs Prompts/Meeting Transcript Summarizer Prompt.md into your vault automatically, and the "Summarizer prompt" setting points at it by default — customize the file if needed. (To install it by hand, copy samples/Meeting Transcript Summarizer Prompt.md from the plugin's GitHub repo.)
  2. To use a different prompt, change the "Summarizer prompt" path in WhisperCal settings.

Usage:

  1. Choose "Summarize meeting…" from the meeting card's ⋯ menu, or run the "Summarize meeting transcript" command. Either opens an instructions dialog — leave it empty and hit Run for a normal run, or enter one-off custom instructions (e.g., "focus on the budget discussion"). On an already-summarized meeting, the item reads "Regenerate summary…" and regenerates the same way.
  2. A "Summarizing…" banner appears at the top of the meeting note while the LLM runs.
  3. When complete, the LLM should write its summary into the meeting note and set pipeline_state: summarized.
  4. The banner disappears and the Summary rail segment turns green.

The summarizer prompt receives the meeting note path as its target. Your prompt should instruct the LLM to read the linked transcript (available via the transcript frontmatter key) and write the summary into the meeting note.

Auto-summarize: If "Automatic mode" is enabled in settings, summarization starts automatically as soon as you apply speaker tags — no clicks needed. The timeout applies independently to each stage, so a 10-minute timeout gives speaker tagging 10 minutes and summarization another 10 minutes.

Meeting Research

Prerequisite: A meeting note must exist (Stage 1 complete). No transcript is required — research can run before, during, or after a meeting.

Setup:

  1. The plugin installs Prompts/Meeting Research Prompt.md into your vault automatically, and the "Research prompt" setting points at it by default — customize the file if needed. (To install it by hand, copy samples/Meeting Research Prompt.md from the plugin's GitHub repo.)
  2. To use a different prompt, change the "Research prompt" path in WhisperCal settings.

Usage:

  1. Choose "Research meeting…" from the meeting card's ⋯ menu, or run the "Research meeting" command.
  2. The modal adapts to the meeting:
    • Recurring meeting with series prep — it opens minimal. A tag at the top links to the series note whose prompt and default context notes are pre-filled; just click Research.
    • Everything else — expand "Add context notes or customize the prompt" (shown by default when there's no series prep) to reveal the advanced controls:
      • Search and select vault notes to include as context (project plans, policies, prior notes, etc.). Selected notes appear as chips.
      • Additional instructions typed in the text area are appended to the research prompt.
      • Bypass the prompt file entirely by checking "Use as direct prompt"; the text area then becomes the direct prompt that replaces the prompt file.
  3. Click Research to run the LLM in the background.
  4. When complete, the research output is written into the meeting note and research_state: research-done is set in frontmatter. The context notes you selected are recorded in research_notes.

Recurring Meetings & Series Prep

Recurring meetings often need the same preparation every time — the same standing context notes and the same "what should I look into before this one" instructions. A series note captures that prep once and applies it to every occurrence.

Setup:

  1. Set the "Meeting series notes folder" path in WhisperCal settings (leave empty to disable the feature).
  2. The first time you click Research on a recurring meeting, WhisperCal auto-creates a series note in that folder (named after the meeting subject) if one doesn't exist yet.
  3. Open the series note and fill in its prep:
    • research_notes in frontmatter — default context notes as wikilinks, e.g. research_notes: "[[Project Plan]], [[Team Roster]]". These are pre-selected in the Research modal.
    • A ## Research instructions section — free-text instructions appended to the research prompt for every occurrence (e.g. "List open items from the project board and the action items from the previous occurrence"). Keep it to concise, scannable talking points.

The series note is matched to an occurrence by its series_id (durable), then by subject. On every later Research click, its prompt and notes pre-fill the modal automatically, and the provenance tag links straight back to it so you can tweak the prep in one place.

Per-Prompt Model Selection

Each LLM prompt (Speaker Tagging, Summarizer, Research) has its own model selector dropdown. This lets you use a more capable model for summarization while using a faster model for speaker tagging, for example.

Model options are populated from the Anthropic API using the Anthropic API key setting, or the ANTHROPIC_API_KEY environment variable as a fallback. If no API key is available, only "Default" (whatever the CLI tool defaults to) is shown.

How Invocation Works

WhisperCal spawns the LLM CLI as a child process using your login shell (so your PATH includes tools installed via Homebrew, nvm, etc.). The process runs in the background with no terminal window. The working directory is set to your vault root.

The LLM receives a single prompt string constructed from:

  • The path to your prompt file: Follow the instructions in '<prompt-path>'.
  • The target file: Transcript: <path>. (speaker tagging) or Meeting note: <path>. (summarization)
  • Optional context: Microphone user: <name>., Transcripts Folder: <folder>., People Folder: <folder>.
  • For speaker tagging: an output format instruction specifying the expected JSON schema (the plugin hardcodes this — your prompt does not need to define it)

Pre-flight checks: Before spawning the LLM, WhisperCal validates that:

  • The CLI command exists on your PATH.
  • The prompt file exists on disk.
  • The concurrency limit hasn't been reached.

If any check fails, an Obsidian notice explains the problem.

Concurrency and Timeouts

  • Concurrency limit — A maximum number of LLM processes can run simultaneously (default: 2). If you start a job by hand while at the limit, a notice tells you to try again when a running job finishes. Jobs started by Automatic mode wait instead: the card shows an LLM limit badge with a retry countdown, and the job is dropped (with a warning on the card) if no slot frees up within 30 minutes. This prevents overloading your machine or hitting API rate limits.
  • Timeout — Each LLM process is killed if it runs longer than the configured timeout (default: 10 minutes). The process receives SIGTERM, then SIGKILL after 5 seconds if it doesn't exit. A timed-out job shows a notice with the duration.
  • Plugin unload — When you disable the plugin or quit Obsidian, all running LLM processes are terminated (SIGTERM) and job tracking is cleared.

Calendar Caching

WhisperCal maintains a local cache of calendar data so you can browse your schedule offline.

Behavior:

  • Past days are served from cache and never re-fetched (they won't change).
  • Today and future days are fetched live when possible, with cache as a fallback if offline.
  • Pre-fetching — After a successful fetch of today's events, the next N days are pre-fetched in the background (configurable, default: 5 days).
  • Retention — Cached days older than the retention period are pruned automatically (configurable, default: 30 days).

Disclosures

  • Remote services: This plugin connects to the Microsoft Graph API or the Google Calendar API (depending on your chosen provider) to fetch calendar events. Both providers use OAuth 2.0 Authorization Code flow with PKCE via a localhost redirect.
  • OAuth token storage: Refresh and access tokens for Microsoft 365 and Google are stored in the plugin's data.json file inside your vault (.obsidian/plugins/whisper-cal/data.json). They are not encrypted at rest. If your vault is synced (Obsidian Sync, iCloud, Dropbox, git, etc.) or backed up, those tokens travel with it — anyone who can read the file can act as you against the calendar provider until the tokens are revoked. To clear them, click Sign out in settings; to invalidate them server-side, revoke access in your provider's account portal (Microsoft 365 or Google account → security → app permissions).
  • Other secrets in data.json: the same unencrypted data.json also holds the optional Anthropic API key (used only to populate model dropdowns) and, for the Google provider, your Google OAuth client secret. Like the tokens above, these are stored in plaintext and travel with a synced or backed-up vault. Treat the file as sensitive.
  • People search: Looking up people (for example the Important organizers autocomplete) queries your provider's directory — Microsoft Graph (People.Read, User.ReadBasic.All) or the Google People API (contacts, read-only).
  • Teams meeting chat: With Pull Teams meeting chat on (the default, Microsoft calendars only), WhisperCal reads the meeting's Teams chat through Microsoft Graph (Chat.Read) and writes it into the meeting note. See Teams Meeting Chat.
  • WhisperCore data file: On its first load after upgrading from 0.8.x, WhisperCal reads the WhisperCore plugin's data.json (.obsidian/plugins/whispercore/data.json) once to import your provider credentials, sign-in tokens, and LLM settings. It never writes to that file.
  • OS account name: The first time it loads, WhisperCal asks the operating system for your account's full name (id -F on macOS, a PowerShell lookup on Windows) to pre-fill the Microphone user setting. The name stays in your settings; it is only passed on as part of LLM prompts.
  • Closing the meeting app: With Automate meeting recording on, stopping a recording from WhisperCal force-quits the meeting app it launched (killall on macOS, taskkill on Windows).
  • External file access: The MacWhisper integration reads and writes to the MacWhisper SQLite database at ~/Library/Application Support/MacWhisper/Database/. This is required to match recordings and extract transcripts. No data leaves your machine during this process.
  • Recording API: When using the Recording API source, WhisperCal communicates with a localhost REST API to start/stop recordings and poll transcription status; the start request carries the meeting subject and attendee names. All communication is local.
  • LLM invocation: When you use the speaker tagging, summarization, or research features, WhisperCal spawns an external CLI tool (default: claude) as a background process. Your transcript and meeting note content are passed to that tool. The LLM process runs locally but may send data to a remote API depending on the CLI tool's configuration. Review your LLM provider's privacy policy to understand how your data is handled.
  • LLM trust boundary: The default Additional flags value is --dangerously-skip-permissions, which lets the CLI read and write files without interactive approval — necessary because the LLM runs headlessly with no terminal to answer prompts. The catch: the content sent to the LLM includes third-party-controlled text — transcribed audio, calendar attendee names, and invite subjects from people outside your control. A crafted meeting name or spoken sentence is a potential prompt-injection vector that, combined with skip-permissions, could drive the CLI to take file or shell actions rooted at your vault. Only run these features against meetings and an LLM CLI you trust. To reduce the blast radius, replace the default flag with a scoped --allowedTools set (or remove it and approve actions another way) at the cost of headless convenience.
  • LLM model discovery: If an Anthropic API key is configured (the Anthropic API key setting, or the ANTHROPIC_API_KEY environment variable), WhisperCal fetches available Claude models from the Anthropic API to populate per-prompt model selectors. No other data is sent.
  • Desktop only: This plugin uses Node.js APIs (child_process, os) and, on macOS, AppleScript, and is not available on Obsidian Mobile.

Troubleshooting

"Client ID is required" (Microsoft)

The Client ID must be filled in before you can sign in. Tenant ID is optional. See Microsoft 365 Setup.

"Client ID and Client secret are required" (Google)

Both fields must be filled in before you can sign in. See Google Calendar Setup.

Sign-in timed out

The sign-in flow is valid for 5 minutes. If it times out before you complete sign-in in the browser, click Sign in again.

Calendar shows "Offline" with no events

  • Check that you're signed in (Settings > WhisperCal > Calendar should show "Signed in" under Connection).
  • Try clicking the refresh button in the calendar header.
  • Verify your Azure AD app has the Calendars.Read permission.

No MacWhisper recordings found

  • Ensure MacWhisper is installed and has recordings in its database.
  • Check that the recording happened within the match window (default: 15 minutes of the meeting start time). You can increase this in settings.
  • MacWhisper must have completed transcription before a transcript file can be created.

LLM job fails immediately

  • Verify the CLI command setting matches an installed CLI tool (e.g., claude). WhisperCal checks your login shell's PATH, so tools installed via Homebrew or nvm should be found automatically.
  • Ensure your Transcript post-processing prompt or Summarizer prompt path points to an existing file. The path can be vault-relative, absolute, or start with ~/.
  • Check the Obsidian developer console (Cmd+Option+I on macOS, Ctrl+Shift+I on Windows) for [WhisperCal] log entries with more detail. Turn on Debug logging in settings for verbose diagnostics (LLM commands and stdout, speaker tagging, and voiceprint enrollment), filterable by the [WhisperCal: prefix.

Speaker tagging modal shows no AI suggestions

  • The LLM's stdout must contain a fenced JSON code block with the expected schema (see Required LLM Output Format). If parsing fails, speakers are shown without proposals.
  • Check the developer console for the raw LLM output to debug prompt issues.

Speakers tagged but not matched acoustically next time

  • Enrollment needs a Tome voiceprint sidecar alongside the transcript. If a sidecar was expected but couldn't be resolved, WhisperCal shows a Notice ("speakers tagged, but not enrolled") — turn on Debug logging to see which sidecar paths were tried.
  • If you see "enrolled … without a people note," create a People note for that person so the voiceprint library stays aligned with your People folder.
  • Matching too loose or too strict? Adjust the Voiceprint match floor setting.

Auto-tag never skips the modal

  • "Auto-tag when all speakers match" only fires when every speaker is a voiceprint match at/above the Auto-tag confidence floor (default 0.80). One unmatched or below-floor speaker sends the whole recording to the modal — turn on Debug logging to see each speaker's cosine.
  • It also requires the recording to have a Tome voiceprint sidecar and enrolled libraries to match against; with nothing to match, nothing auto-tags.
  • For a fully hands-off background run (no clicks), Automatic mode must also be on. With Automatic mode off, the auto-tag applies when you click the Review speakers button.
  • Re-reviewing an already-tagged transcript never auto-skips — confirmed names are treated as ground truth and aren't re-matched.

Auto-tagged speakers aren't improving my voiceprints

  • This is by design. Silent auto-tags (skipped modal) never enroll or correct a library, to prevent drift. To intentionally update a library, review that recording in the modal and apply it there.

"LLM concurrency limit reached"

  • The default limit is 2 simultaneous LLM processes. Wait for a running job to finish, or increase Max concurrent LLM processes in settings.

LLM process timed out

  • The default timeout is 10 minutes. For long transcripts, increase the LLM timeout setting. Set to 0 to disable the timeout entirely.

Status rail segments are grayed out

A rail segment stays neutral (and isn't clickable) until its stage's artifact exists — the pipeline advances left to right:

  • Transcript requires a meeting note to exist first.
  • Speakers requires a linked transcript.
  • Summary requires speakers to be tagged (pipeline_state: tagged).

Once a stage is reached and waiting on you (speakers to tag, summary to run), its segment turns the warning color instead of gray — gray always means "not reached yet".

The smart action button shows the single next step that is available (before a transcript exists on the Recording API source, that step is the capture button in the gutter), so if nothing seems clickable, those two are where to look.

Meeting note attendees aren't wiki-linked

  • Set the People folder path in settings.
  • Ensure people notes have a full_name or email field in frontmatter that matches the attendee's Microsoft 365 display name or email address.

Migrating Legacy Notes

Meeting notes created before WhisperCal (or before the unlinked recordings feature) have no macwhisper_session_id in their frontmatter, so their MacWhisper recordings show up as "unlinked" even though a note exists. docs/migrating-legacy-notes.md explains how to backfill the key, one note at a time or in bulk. It applies to the MacWhisper source on macOS only.
