Realtime collaborative documents without an account, server, or install. Open a doc, send a link, start typing together.
Realtime CRDT
Every participant edits the same document and converges to the same state, no matter who typed what first.
Local-first
Nothing lives on our servers. The document stays in the peers' tabs and disappears when the last one closes.
One-click invite
Start a doc, copy a link, paste it. The recipient joins and starts editing — no account, no install.
Works behind NATs
Automatic Rapidly-hosted TURN fallback when a direct path is not possible, so your doc still syncs on coffee-shop Wi-Fi.
