This is pretty neat. I gave it a single sentence to describe a Saas that uses forbidden magic and astral talismans to boost client efficiency, and maximize their objectives.
It created a landing page and a questionnaire to funnel people into email collection.
The landing page looked the best, a gradient with some pretty funny/clever copy related to my prompt. If I was making this for real, I would want more. Some images, more copy about my products, maybe even some animations.
The questionnaire pages felt plain, and could use some styling. It also felt like there were too many, and would probably see an engagement drop off.
The app gives some basic styling options that it does automatically as well as ways to adjust the copy.
The app also provides a way to deploy this, but I think I would want the underlying JS so that I could tailor this to my needs, effectively using it to get over the "blank sheet" problem.
