Your best debugging session is three tools and two weeks ago. The fix is in there — in a Claude Code thread, or was it Cursor? Callimachus is the index card that finds it in a keystroke, so you stop re-explaining yourself to robots.
Filed, cross-referenced, instant.
One local index behind every surface. Built for the way you actually go looking for something you half-remember.
Find it by what it was about
Keyword search (SQLite FTS5) fused with on-device semantic similarity, so a vague memory — “that vector index migration” — surfaces the right thread even when you've forgotten the exact words. Filter by source, project, or recency.
It never leaves your machine
The index, the embeddings, the search — all on disk, on your computer. No account, no sync, no telemetry. The quietest tool in your stack.
Always current, never in the way
A background watcher catalogues new sessions as you work. Reindex any source on demand; forget it's running the rest of the time.
Hand the past to the present
Copy a thread's packed context, insert it into your editor, export it to Obsidian, or let the MCP server feed it to an agent on demand. Your history becomes raw material again, not just a read-only archive.
Four ways into the same catalogue.
One index, read from wherever you already are.
- № 01Desktop app
A native app for macOS, Windows, and Linux. Browse, search, and read every thread; chat over your own history; export to Obsidian. Auto-updates.
- № 02VS Code & Cursor
A sidebar and transcript tabs inside your editor. Same local index, no context-switch. Works in VS Code, Cursor, and VSCodium.
- № 03cal CLI
`cal search`, `cal recent`, `cal cat` — grep your past sessions from the terminal and pipe context straight into the next agent.
- № 04MCP server
Expose your indexed history to any MCP client. Agents can search your past work and pull the thread they need, on demand.
A library that doesn't read over your shoulder.
Cookieless, aggregate analytics on this site — no tracking cookies, no cross-site profiles. No telemetry in the app. Your conversations are indexed where they already live — on your machine — and stay there. Open source under AGPL-3.0, so you never have to take our word for it.
Questions, briefly answered.
Open the catalogue.
Free, local, and quietly yours. Run the app once and every thread you've ever written is a keystroke away.
