Documentation

Dóru is a local-first genealogy app for the AI era. Your family tree lives in a plain folder on your disk, works fully offline, and can be driven by AI agents — through the built-in chat or any MCP/ACP client.

• Local-first. Nothing leaves your computer unless you say so. A project is a single .doru file; photos live in a media/ folder next to it. No accounts, no cloud, no telemetry — your data stays with you.
• Open source. The whole app is MIT-licensed — free for any use, modification, and redistribution, with the full source available.
• AI-native. Talk to an agent in the app, or let external tools (Claude Desktop, Cursor, coding agents) work with your tree over MCP/ACP.
• Plain files. The tree is a single SQLite file; photos are ordinary files in a media/ folder.
