What you get
A viewer built for AI-generated pages
Most HTML viewers assume you wrote the code. This one assumes a model did — so it shows you the render, the errors and the mobile width without asking you to set anything up.
Renders as you type
No run button. Edit the markup and the preview follows within a moment, with HTML, CSS and JavaScript all live.
Desktop, tablet and phone
Check the same page at three viewport widths without resizing your window, then open it full screen to see it at real size.
Paste or open a file
Paste code straight from a chat, or open an .html file from your machine. Copy or download it again whenever you like.
Sandboxed by design
Your page runs isolated from this site, so scripts in the code you are testing cannot touch anything outside the preview frame.
Nothing leaves your browser
The code is never uploaded and never stored on a server. Your draft is kept locally so it survives a reload, and Reset clears it.
One step from a real URL
When the page looks right, publish it to a live address you can send to anyone — free plan, three sites, no card.
A preview is only for you. A URL is for everyone else.
This page never leaves your browser, which is exactly why you cannot send it to anyone. When the render looks right, publish the same code to a real address with SSL — and a custom domain when you want one.
Prefer a written walkthrough? Preview AI HTML before you publish. Sending it to a client? Live preview, not a ZIP.
