yarnnn

About

yarnnn is a shared workspace where you, your team, and every AI you use collaborate directly on the same files. Unlike typical AI tools that each keep separate copies of your work, yarnnn ensures every edit is signed by its author, whether human or AI. You can connect services like ChatGPT, Claude, or Gemini via MCP. Their contributions go directly into a real file system you control, where everything is named, versioned, attributed, and remains findable over time. This is not a chat log or a memory feature limited to one AI provider. The service is free for two users, and adding an AI connection does not count as a paid seat.
