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.

yarnnn syncs your Slack, Gmail, Notion, and Calendar to build a living understanding of your work. Then it produces real deliverables -- status updates, briefs, summaries -- that get better with every edit. No prompting. No copy-paste. Set it up once, and your 10th delivery is better than your 1st. Context-powered AI that actually does your work, not just answers your questions.
