Summary
Muesli is a real-time collaborative Markdown editor for teams and AI agents working in the same plain .md file. People can follow live cursors and presence, discuss changes in comment threads, submit tracked suggestions, and use append-only history with snapshots. Editing tools include inline preview, a source toggle, KaTeX math, Mermaid diagrams, editable tables and callouts, wikilinks, and backlinks. Claude Code, Cursor, Codex, Copilot, and Gemini CLI can contribute through MCP or by editing the file directly. When a person is present, agent edits become suggestions for review. Guest links offer viewer, commenter, or editor roles without requiring accounts. Storage options include local files, S3-compatible services such as AWS S3, Cloudflare R2, and MinIO, plus GitHub, Gitea, Forgejo, and Google Drive. Muesli is free and open source under AGPL-3.0, with web, Windows, macOS, Linux, and self-hosted availability. Self-hosting uses one Docker image, but durable documents and history require Postgres and Redis. The hosted service says document contents stay in user-chosen storage and are not used for training.
Who it is for
Muesli suits teams that collaborate on Markdown files and want AI agents to contribute alongside people. It also fits users who want local or self-hosted storage options.
What is good
- Live collaboration includes comments and tracked suggestions.
- Guest links provide role-based access without accounts.
- Supports several AI coding agents through MCP or direct editing.
- Free and open source under AGPL-3.0.
What to know first

Verdict
Muesli combines Markdown editing, team review, and AI-agent contributions around plain .md files. Consider its Postgres and Redis requirements if you plan to self-host durable documents and history.
