Reviewing could be so easy.easy, fast, reliable, and fun.
Highlight, comment, rewrite. Your agent folds every note and republishes until you say it's right.
A real coauthr document — open it, comment, ask the agent
The empty quadrant.
Google Docs work for people. Markdown works for coding agents. Chat artifacts disappear with the chat. Coauthr gives both sides the document they need.
coauthrnative to bothBuilt for developers who work with coding agents. Reviewers only need the link.
Your team gets the Google Docs experience: highlight, comment, rewrite, share. Your agent writes from the terminal and reads every note back as data.
The document itself gets what neither format had: real typography, tables and diagrams, live across sessions, machines and collaborators.
Code still belongs in diffs. Coauthr is for the documents about the code — plans, briefs, decisions.
Everything your docs need for creative and collaborative review.
Real sentences, held back to a whisper, so the only thing at full contrast is the move itself.
Comment
Highlight words and start a conversation.
Edit
Rewrite in place; inspect Clean versus Markup.
Ask the agent
Question the passage where it lives.
Multiplayer
Everyone in the same document at once; reading needs no setup.
Easy to navigate
The Contents rail follows a long document as you scroll; every heading is a share link.
Great reading experience
Theme, width and spacing belong to the reader — the same document, four ways.

What happens at fifty.
Your agent publishes the fifty-first document. This is the entire wall — you have seen all of it now.
Make room for “Sprint 14 retro”
All 50 of your documents are in use, so the new one is stored and waiting — you can already read its preview. Delete an old document to publish it, or go Pro and never think about slots again.
Least recently updated
Deleting is permanent and always your explicit choice. Until you decide, the new document is safe — stored in full, live the moment a slot opens.
You have deleted 6 documents this month to stay under fifty. Pro keeps them all.
Publishing never fails.
Your agent gets a link back every time. The fifty-first document is stored in full and shows you its preview — the wall is a decision you make later, not an error mid-run.
No half-states.
A document is live with full capability — comments, edits, agent sessions — or it is gone. Nothing archived, nothing frozen, nothing to explain: fifty documents that all work.
You choose what leaves.
The least-recently-updated documents are listed first because they are almost always right — but nothing is ever deleted without your explicit say. Or you go Pro, and nothing leaves the desk again.
Why I built coauthr.
I wanted to review Claude Code documents faster, share them with colleagues, and make the language less sloppy before I sent it. Markdown files just don't work for high-fidelity designs.
