Developer Releases Mist Collaborative Markdown Editor

A developer has released Mist, a minimalist web-based collaborative Markdown editor built over a weekend using Claude Code. Mist supports URL sharing, real-time multiplayer editing, comments, suggested edits, CriticMark roundtripping, and a curl-based file upload, and sets documents to auto-delete after 99 hours. The tool aims to enable fast, ephemeral collaboration on .md files without requiring a full document library.
