Sayhi-bzb/Agent-HTML — reverse-engineered prompt

Build me a web app called Agent HTML where I can paste or generate HTML and then edit it visually instead of digging through raw code. I want it to feel like editing a Notion page, with the HTML broken into blocks that I can drag, move around, reorder, and preview live.

It should handle artifact style pages like dashboards, reports, briefs, Kanban boards, charts, tables, images, and responsive layouts. Add a clean preview area with controls for theme switching, custom themes, and different screen or aspect ratio views so I can see how the same content looks in different presentations.

The important part is the human and AI workflow. I should be able to review the artifact, point out what needs changing, leave feedback, and have the agent update the editable version without losing the structure. Make it polished, simple, and useful for people who want a canvas with AI instead of a normal chat UI.
