What it does
Callimachus indexes conversation history from 11 coding tools, including Claude Code, Codex and Cursor, on your own machine. It combines SQLite full-text search with on-device vectors, so you can find past work across all of them. It comes as a desktop app with a chat view, plus an MCP server, a CLI and a VS Code and Cursor extension. Everything stays on your machine.
