Liminal — AI Note Assistant for Obsidian

Liminal is an AI-powered assistant for Obsidian that helps you build a richer knowledge base — faster. Using the Anthropic Claude API (Bring Your Own Key), it generates structured notes, suggests relevant tags and links, and can even turn YouTube transcripts into organized notes.

How it works

Note generation

Liminal structures your raw text into a consistent format:

# Title
## Summary
## Key Ideas
## Content
## Tags
## Links

It also cross-references your existing vault notes to suggest relevant [[wikilinks]].

Semantic search & link suggestions

The link suggestion feature uses a local keyword-based pre-filter to narrow down candidates before sending the top 15 to Claude — keeping API costs minimal.

YouTube notes

Liminal fetches the video transcript automatically. If the transcript is blocked, it offers a manual fallback where you can paste the text yourself. Notes from videos include a Notable quotes section in addition to the standard structure.

Requirements

• Obsidian 1.4.0 or later
• Desktop (Windows, macOS, Linux) — not available on mobile
• An Anthropic API key

---

Privacy

• Your API key is stored locally in your vault's plugin data
• Note content is sent to the Anthropic API only when you trigger a command
• No analytics, no telemetry, no external servers beyond Anthropic
• Vault access: the plugin enumerates all markdown file paths in your vault to power link suggestions and semantic search. File paths are used locally for filtering; only the content of the active note (and up to 15 candidate notes for link suggestions) is ever sent to the Anthropic API.
