Shared Docs
Documents several people can write in at the same time — live cursors, no lost edits, no third-party account required.
Sign in with a one-time link sent to your email, or open a document someone shared with you by URL. Everything is stored on this server.

Edits merge with a CRDT, so two people typing in the same paragraph both keep their work — offline stretches included.

Sign-in is a one-time emailed link, confirmed in the same browser that asked for it.
Its counterpart
Paperseal
This app is for a document several people write together. Paperseal is for the opposite case -- a finished document sent to one person. Upload it, name who gets it, send. They read it without making an account, you can see who opened it, and you can revoke access whenever you want.
Open paperseal.app- A forwarded link gets nowhere. Opening it grants nothing -- it offers to mail a single-use confirmation to the recipient's own address, which a forwarded copy can't receive.
- Revoking works immediately. No public or pre-signed URLs are ever issued, so access stops on the very next request.
- The access log is append-only. Deleting a document leaves its history intact -- the same idea as the discussion beside these docs.
Both are built and hosted here, with no Google account anywhere in either one.
