prosa

a work log for AI-agent sessions

prosa /ˈpɾɔ.zɐ/  noun A conversation, a chat, an informal exchange of ideas. Prosa lets you have a conversation with your own work history.

prosa turns scattered Claude Code, Codex, Cursor, Gemini, and Antigravity session histories into one local, searchable timeline. It is built around a single load-bearing question:

What did I work on in the last N days?

— and the natural follow-ups around it: where, on which projects, with which agents and models, using which tools, taking how long, costing roughly what.

What prosa is — and isn't

prosa is a local-first, offline-friendly work log. Three small Go binaries share one module and one typed contract:

• prosa — the CLI you actually use. Reads the local store by default.
• prosa-server — a thin personal API server (Postgres + S3-compatible object storage) for the cross-device view.
• prosa-panel — a server-rendered web panel that talks to the server.

It is not a chat manager, a residential TUI, an analytics warehouse, or a multi-user SaaS. The shape and the boundaries live in INTENT.md; read that file before proposing anything substantial.
