Everything a shared folder should be
Built like a native app, because it is one. Fast, quiet, and firmly on your side.
Real-time collaboration
Live editing with CRDT conflict resolution — every keystroke lands instantly on both devices, offline-safe.
Peer-to-peer, private
Your files travel directly between devices. No server ever sees or stores your folder contents.
AI assist — your key
Bring your own API key. Requests go straight from your device to your provider; the key lives in Windows secure storage.
Comments & review
Comment on selections inline, review changes side by side, and keep the conversation next to the work.
Offline-safe sync
Lose the connection and keep working. Changes queue up and merge cleanly when you're back.
No accounts
Nothing to sign up for. Install, pick a folder, share a code. That's the whole onboarding.
How it works
Three steps, one direct connection.
Pick a folder
Choose any folder on your PC as the shared workspace — documents, code, notes, media.
Share the code
CoFolder generates a short session code. Your collaborator types it in and connects directly.
Work together
Edit in real time, leave comments, chat in the session — all peer-to-peer, all on your devices.
Get CoFolder for Windows
