Composer

Meet Composer

Composer is a collaborative Markdown editor for people and AI agents working on the same documents. It keeps writing in a plain-text format while adding a shared workspace for real-time editing, comments, and team access. Users can work on notes, specifications, and other documents without converting them into a proprietary document format.

An MCP connection gives supported agents a way to participate in the document workflow, allowing people to review and develop material alongside automated assistance. Sharing and export options help move the results into other tools. Composer is useful for teams that want readable source files with the coordination features of an online editor.
