About this app

Arca opens on the camera. You frame a paper, shoot, and it is filed — locally first, then on servers in the European Union — with a short summary, a category, a place and a date.

Every document starts private. The assistant you already use can read a file only when you grant it. Connecting is one address, https://arca.blue/mcp, which you paste as a custom MCP server (Claude and other assistants that speak MCP). That host’s cloud calls ours; it is not end-to-end encryption to the model. Disconnecting in the app cuts access at once.

Arca works if you never connect an assistant. The archive is yours: export or delete the account and it is gone.

Plans
• Free — 100 new files a month, camera, library, in-app questions, AI connector
• Plus — €5.99/month, 1000 new files a month
• Lifetime — €39 once, Plus quota forever

The quota is new files per calendar month, never the papers you already stored. The connector is on every plan.
