About
Copana is an open-source, markdown-first personal AI assistant built on top of Claude Code. Rather than a hosted SaaS product, it's a git repo you clone — your AI's memory, personality, and context all live as plain text files on your own machine. It uses Claude Code's subagents, output styles, and status line features to give the assistant persistent memory and a defined personality across sessions.
Individual developers or technical users who want a highly personalized AI assistant that remembers them across sessions, and are comfortable managing their context via git. Not a fit for non-technical teams expecting a polished web UI.
Pros & Cons
Pros
- check Everything stays local — no cloud sync, no telemetry, full data ownership
- check Persistent memory and active learning without any database or embeddings infrastructure
- check Lightweight compared to OpenClaw: ~50 source files vs thousands, setup in under 30 seconds
Cons
- close Requires Claude Code (and therefore a Claude subscription) to function
- close Not a true hosted workspace — team collaboration features are limited compared to a proper multi-user platform
- close Mobile access requires setting up a Telegram bot and git sync manually
