  FAQ

claude-obsidian turns the things you read into a knowledge base that keeps getting more useful. Drop a paper, an article, a transcript or your own notes into the vault, and Claude reads them, writes linked notes with sources, and files everything into one connected knowledge graph you can explore in Obsidian.

- Capture. Put sources in inbox/. The originals are kept, untouched, so every summary can point back to where it came from.
- Connect. Claude writes linked pages, indexes and maps of content, so new ideas join the graph instead of piling up.
- Ask. Get answers from what your vault already knows, with citations, without changing a single file.
- Save. Keep the answers worth keeping as notes, one at a time, when you ask.
- Check. A health check finds dead links, orphan pages and gaps before they spread.

Everything stays as plain Markdown files on your computer. No cloud database, no lock-in, no telemetry. Apart from the AI tool you chat with, nothing leaves your machine unless you say so.

See the vault

The result is a normal Obsidian vault that stays useful with or without an AI: browse it in Graph view, or lay it out as a map in Obsidian Canvas.
