Your manuscript. Their feedback. Clear roles.

Co-author: full edit access. They can write, reorder chapters, modify the story bible. They see everything you see. Editor: suggest mode only. They highlight, comment, and propose changes. You accept or reject. No direct edits to your prose.

Beta reader: read-only with inline reactions. They can highlight passages and leave comments, but can't change a word. They see the manuscript as a reader would. Proofreader: read-only with typo flagging. They mark grammar, spelling, and punctuation errors. One-click accept to fix.

Send an invite link to anyone. They don't need a paid account. They don't need to install anything. They open the link and they're in.

Grant access to the full manuscript or specific chapters. Sending chapters 1-5 to your beta reader group? They only see those five chapters. Your unfinished draft of chapter 6 stays private.

Two co-authors can write in the same chapter simultaneously. Cursors show where each person is. Changes merge in real time. No version conflicts. No "your turn" emails.

Editors and beta readers work async by default. They leave comments. You review them on your schedule. A notification badge shows how many unread comments are waiting. No Zoom call required.

Highlight any passage and leave a comment. Tag it as a question, suggestion, continuity issue, or praise. Filter comments by type so you can batch-process all continuity flags at once.

Comments persist across revisions. If you rewrite a paragraph, the comment follows the highlighted text. If you delete the passage, the comment archives automatically.
