Checking an AI-built form? Judge it filled in, too.

Imagine filling in a class signup form on your phone. You enter two names, get interrupted, then return. Was the first box for you or the person attending? The words that explained it disappeared when you typed. If you ask an AI website builder for a clean, minimal form, check more than the empty preview. W3C's existing forms guidance says placeholder text is not a replacement for labels, and disappearing instructions make answers harder to check before submitting. This is established accessibility guidance, not evidence that a particular AI builder gets it wrong. For a signup page, I would fill every box with harmless test details, move away from the active field, and come back. Can I still tell whose name goes where and which date format was requested without deleting an answer? Keep those labels and instructions visible, and have the field labels properly associated in the page code for assistive technology. That is a check I would use before sharing the page, not a test I have run here. A form can look wonderfully uncluttered before anyone has to use it.
