Someone built a Claude Skill that turns HTML output into a live collaborative document.

Claude Code generates the HTML file. You open it in a browser. Leave comments directly on the page. Claude reads them and updates the file in real time. Then walks you through every change like a tour.

Google Docs style iteration but for anything Claude builds.

Research reports. Mockups. Code explorations. All editable live in the browser.

This is exactly why HTML is becoming the most useful output format for AI work right now.

I wrote the full breakdown on that right here.
