The record

Product: Muesli is a real-time collaborative Markdown editor for teams and AI agents that edit the same plain .md file.
Live collaboration: It offers live cursors and presence, comment threads, tracked suggestions, and append-only history with snapshots.
Markdown tools: The editor includes inline preview and source toggle, KaTeX math, Mermaid diagrams, editable tables and callouts, wikilinks, and backlinks.
AI agents: Claude Code, Cursor, Codex, Copilot, and Gemini CLI can collaborate through MCP or by editing the file directly.
Agent review: When a human is present in a document, agent edits become suggestions for review.
Sharing: Role-scoped guest links support viewer, commenter, and editor access without requiring collaborators to have accounts.
Storage integrations: The maker lists local files, S3-compatible storage including AWS S3, Cloudflare R2, and MinIO, GitHub, Gitea, Forgejo, and Google Drive.
Self-hosting: Muesli can be self-hosted with one Docker image; durable documents and history require Postgres and Redis, and sign-in can use an OIDC issuer.
Platforms: The maker lists browser use and desktop builds for macOS, Windows, and Linux; the download page labels the desktop downloads “Coming soon.”
CLI: A CLI is available to install with the maker’s shell installer on macOS and Linux, with a Windows ZIP linked from releases.
Privacy: The hosted service says document contents remain in storage chosen by the user and are not read, mined, or used for training.
Security: The privacy policy states service traffic uses TLS, production access is restricted, and audit logs record security-relevant actions.
Data handling: The hosted service collects account data, session data, audit logs, workspace and document metadata, connected-storage credentials, and transient request data; it says it runs no analytics or third-party trackers.
Support: The maker provides support and privacy contact by email at [email protected].
