# AI Prompt Input Box

> AI prompt input box for app builders and chat products: a liquid-glass composer with a typing placeholder, platform chips, a keyboard-friendly model menu, file attachments and a breathing send button. Enter sends; an optional demo build log then morphs into a preview card. Wire onSubmit to your own generator.
