What can I do if I do not like the website the AI assistant built?

The same prompt can give different results, so you can send the same prompt again and compare. Tell the assistant to create a new website project and ignore the existing ones, so it builds a fresh version instead of changing the one you have. A vaguer prompt gives more variation between versions.

To fine tune a version you like, edit it in the website builder: add padding, adjust the corner radius, resize images and boxes, and add, delete or edit text. You can also tell the AI assistant to make the change for you. The result is usually mobile friendly out of the box, with only small tweaks needed, such as image size or centering on mobile.

If a change made things worse, use the History button in the website builder to rewind to an earlier version.

For inspiration, look at design galleries such as Behance and Dribbble, but aim for a page that converts rather than one that is only beautiful.
