A real-time collaborative document editor.
A document you write alone is monochrome. Colour arrives with other people.

See the whole product.

Dashboard Every document leads with its real first lines — not just a title and a date.

Comments Comment on a phrase, then rewrite around it. The note holds its place.

Sharing Invite people by role, or hand out a link. Access is enforced on the server.

Version history Every version is kept. Preview any point in time, and restore it.
Colour means a person.
Every collaborator gets one hue — in their cursor, their selection, their comments. A page with four people in it is never monochrome.
The band along the top edge is everyone in the document right now, each in their colour.

- Convergence rig green across ten clients
- Keystroke to glyph under sixteen milliseconds
- Comments survive a rewrite
Type in it — the collaborators are scripted, the editor isn’t.
