Hi! We built something for the Meta Global AI Developer Hackathon and I'd like your eyes on it.
Mnemosyne is a self-hosted AI team memory and corporate wiki. Your team's knowledge lives as markdown notes in your own git repository. Claude, Cursor or any MCP-capable AI can search, read and write it, so every assistant shares one memory. Mnemosyne then writes the documentation for you: an article, a PDF handbook and architecture diagrams per project, painted by an image model. Your notes stay on your server, and nothing calls an AI model until an admin agrees to the cost.
One real number: it documented 92 projects in a single run for $0.51 in text-model cost. The image model is billed separately, per picture.
Open source (Apache-2.0). Free for up to 4 people. Every install starts with a 30-day trial with everything unlocked. After that, 5 or more seats need a licence at $99 per seat per year, with 10% off from 5 to 50 seats.

Tell me what you think. A star on GitHub helps a lot!
