The best work is written together
A multiplayer markdown editor for you, your team, and your agents.
Composer is a real-time, multiplayer markdown editor where people and AI agents work side-by-side. Instantly share markdown generated by your agent with teammates, edit in real time, and leave comments and suggestions. Your agents join as true collaborators, working directly alongside you and your team.
Use Composer with your agent
Composer connects to your AI agent over MCP, so the markdown your agent writes lands in a shared document your whole team can edit, comment on, and refine together in real time.
