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.

Desktop only · Requires an Anthropic API key

Installation

From the Community Plugins browser

  1. Open Settings → Community plugins → Browse
  2. Search for Liminal
  3. Click Install, then Enable

Manual installation

  1. Download main.js and manifest.json from the latest release
  2. Create a folder <your-vault>/.obsidian/plugins/liminal/
  3. Copy both files into that folder
  4. Reload Obsidian and enable the plugin in Settings → Community plugins

Setup

  1. Go to Settings → Liminal
  2. Paste your Anthropic API key (sk-ant-...)
  3. Choose a model (Claude Sonnet 4.6 is recommended)

You can get an API key at console.anthropic.com. The plugin uses the API directly from your machine — no data is sent to any third-party server.

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
