Novyx for Obsidian

Persistent AI memory for your Obsidian vault.

Your AI assistant forgets everything between sessions. Vector search plugins just search your notes when you ask a question — they don't remember. Novyx gives your vault a persistent memory layer that survives across sessions, surfaces hidden connections between notes, and can be rolled back if something goes wrong.

What it does

• Ghost Connections — The sidebar shows semantically related memories for the note you're editing, even when there's no shared keyword or explicit wiki-link. Click any result to jump to that note or insert a [[wiki-link]] inline.
• Remember current note — A command that stores the active note in Novyx's persistent memory layer with a vault-scoped tag. Run it from the command palette or bind a shortcut.
• Works with your existing vault — No migration, no lock-in. Your notes stay as plain markdown. Novyx runs alongside.

Data and privacy

This plugin sends note content to the Novyx API (novyxlabs.com) — that's how persistent memory and Ghost Connections work. You should know exactly what gets sent and when:

• "Remember current note" command — Sends the full body of the active note (with YAML frontmatter stripped) to Novyx so it can be stored in your memory layer. Tagged with your vault name and the file path.
• Ghost Connections sidebar — When you open or switch notes, sends the note's title plus the first 1000 characters of the body as a similarity-search query. Used only to find matching memories — not stored as a new memory.
• Settings sync — Your API key and other settings are stored locally in Obsidian's plugin data folder. They're never sent anywhere except to authenticate API requests against Novyx.

Notes are sent over HTTPS to your configured Novyx endpoint (default: https://novyx-ram-api.fly.dev). You can self-host Novyx Core to keep data on your own infrastructure — see the Novyx Vault repo for self-hosting details.

If you need a fully offline second brain, this plugin is not the right fit. The whole point is the cross-session memory layer, which by definition lives outside your vault.

Install

From the Community Plugins marketplace (recommended, coming soon)

1. Open Obsidian Settings → Community plugins → Browse
2. Search for Novyx
3. Install, enable, and configure your API key in settings

From BRAT (beta / manual install)

1. Install the BRAT plugin
2. Add novyxlabs/novyx-obsidian as a beta plugin
3. Enable Novyx in Obsidian settings

Manual

git clone https://github.com/novyxlabs/novyx-obsidian.git
cd novyx-obsidian
npm install
npm run build

Then copy main.js, manifest.json, and styles.css into <your-vault>/.obsidian/plugins/novyx/ and enable the plugin in Obsidian. The folder name must match the plugin id from manifest.json (novyx).

Setup

1. Get a free Novyx API key at novyxlabs.com (no credit card, 5,000 memories included).
2. Open the plugin settings in Obsidian and paste your key.
3. (Optional) Customize the vault tag, ghost connection threshold, and result limit.

Usage

• Open the Ghost Connections sidebar: click the brain icon in the ribbon, or run "Novyx: Show Ghost Connections sidebar" from the command palette.
• Remember a note: open any markdown note and run "Novyx: Remember current note" from the command palette. The note is stored in your Novyx memory layer with tags for this vault and the note's file path (used as a stable identity key).
• Find connections: as you switch between notes, the Ghost Connections sidebar updates automatically with semantically related memories. Click a result to open the source note, or click "Insert wiki-link" to add [[Note Name]] at your cursor position.

Why this is different

Every other Obsidian AI plugin does retrieval — vector search over your existing notes. Close the session, ask again, it all starts from scratch.

Novyx is different:

1. Cross-session memory — The AI remembers what you told it, what you wrote, and how you think — across every session.
2. Ghost Connections — Find semantic relationships between notes that you never explicitly linked. No shared keywords required.
3. Memory rollback (via Vault app) — Undo what the AI learned at any point in time. Cryptographic audit trail for every operation.
4. Unified memory — The same memory layer works across Obsidian, Claude Code, and Cursor via MCP. Your coding context shows up in your notes. Your notes show up in your coding agent.

Known limitations (v0.1)

• Rename orphans memories. Memories are keyed to the note's file path. If you rename or move a note, the old memory stays in Novyx but is no longer linked to the new location. A new "Remember" will create a fresh memory at the new path. Ghost Connections will show the old memory as (source note missing: ...) until manually cleaned up. A future version will track renames automatically.
• Desktop only. The plugin is flagged isDesktopOnly: true for v0.1 while we verify the Novyx SDK bundle runs cleanly on iOS/Android. Mobile support is on the v0.2 roadmap.
• No memory dedupe on re-Remember. Running "Remember current note" twice on the same note stores two memories. This is intentional for v0.1 — memory history matters. A future version will let you choose between dedupe and versioning.
