yarnnn

Every AI keeps its own copy of your work. You don't. yarnnn is a shared workspace where you, your people, and every AI you use work on the same files — and every change is signed by whoever made it, human or not. Connect ChatGPT, Claude or Gemini over MCP. Their writes land in a real file system you own — named, versioned, attributed, findable next week. Not a chat log. Not a memory plugin bolted onto one vendor's model. Free for two people, and an AI connection never costs a seat.
