coeditHTML: open-source tool to comment on and co-edit AI HTML artifacts like slides

Vast-Grapefruits · reddit · 2026-09-02

A developer built coeditHTML.com, a free open-source tool that treats AI-generated HTML artifacts like collaborative slideshows: teams can share an artifact, leave comments, and edit directly.

After editing, changes can be exported back to your favorite AI tool as a prompt sent from the app. An MCP server also auto-generates a co-edit link whenever you create an artifact in Claude or another AI tool, making sharing faster. The project is fully open source and the author is soliciting feedback.
