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.
