yarnnn
The AI-first workspace where every change is signed
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.
Hey Product Hunt — Kevin here.
I launched a version of yarnnn here in February that I'd now describe as wrong. It tried to be an AI that did your work for you.
The problem I kept actually hitting was smaller and more annoying. I use ChatGPT, Claude and Gemini every day, and I was the only thing connecting them. Copy out of one, paste into the next, re-explain the context a fourth time — and the real artifact, the doc or the decision, lived nowhere in particular.
So yarnnn is a workspace instead of an agent. Real files you own. Connect any AI over MCP and its writes land in that file system, signed. Open a document and you can see it: you on Tuesday, your teammate on Thursday, Claude on Friday. One file, three authors, every change attributed to whoever made it.
Free for two people. Connecting an AI never costs a seat — an AI isn't a teammate you pay for.
What I'd most like to hear from you: how many AIs are you actually using day to day, and does moving between them register as a real problem, or has it just become normal life? I've built a thesis on it being a problem. Tell me if I'm wrong about that.
