Composer: A real-time markdown editor where Claude Code agents edit alongside you
Composer (usecomposer.md) is a real-time markdown editor designed to solve a specific pain: after a Claude Code agent generates a document, the agent gets cut off from human feedback. You paste the doc into Slack, people comment, but the agent can't see those comments or fix the paragraph everyone is arguing over.
Key Details
- Live collaborative editing — humans and agents edit the same document in real time. The Claude Code agent connects via the Model Context Protocol (MCP).
- Agent capabilities — the agent can read the document, reply to comments, and leave suggestions, just like a teammate.
- Push docs directly — you push a doc straight out of your Claude Code session, no copy-paste dance.
- Comments and suggestions — work today. Access controls are also available.
- Team collaboration — invite teammates into the session; they can also bring their own agents.
- Public docs — free, unlimited, no sign-in required to try.
Who It's For
Developers who use Claude Code to generate plans, specs, or meeting notes, and then need to iterate on those documents with human collaborators without losing the agent's context.
