Why collab belongs on the desk
Emailing FINAL_v12.docx destroys version truth. Typewriter keeps one live manuscript with roles for beta, editor, publisher, and coauthor.
The author invites from the library or the Invite button on the desk. Guests open typewriter.digital/invite/… — the URL never includes a manuscript id.
Live co-write, not a shared folder
Coauthor seats type on the same chapter with colored cursors. The page stays one document. Export, CoAuthor, and search still see the live prose.
Beta readers and editors leave notes and highlights on the page. Editors can suggest; you accept or reject. Nobody silently overwrites your draft unless you gave them a coauthor seat.
Roles that match a real pass
Beta reader: notes and highlights only. Editor: suggests plus comments. Publisher: read pass and light notes. Coauthor: live write with you.
You can change a seat or revoke a pending invite. Waiting invites show in Inbox. Shared books land there for the guest.
