In their own words
Muesli
Muesli is a free, real-time collaborative Markdown editor for teams and AI agents working in the same plain .md file. Collaborators can see live cursors and presence, discuss material 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 work through MCP or edit the file directly. When a human is present in a document, agent edits become suggestions for review. Guest links can grant viewer, commenter, or editor access without requiring accounts. Storage choices include local files, S3-compatible services, GitHub, Gitea, Forgejo, and Google Drive. Muesli is available on the web, Windows, macOS, Linux, and as a self-hosted service, and is open source under AGPL-3.0. Self-hosting uses one Docker image, but durable documents and history require Postgres and Redis. The hosted service says document contents remain in user-chosen storage and are not read, mined, or used for training.
