It's generated, when you try it you can see this is mostly a harness around claude opus 4.7 that helps it create a good design plan, it also supports asking you questions as it goes along, letting you review and feedback on mockups, etc, but ultimately if you look at what it's generating as it does it – it's just code

"Its just code" is meaningless to me. Is the code its generating using mostly well known widgets with predefined knobs, or is every element completely custom and the knobs are created on the spot with slightly different naming and function every time?

I actually think I would prefer the more boring "it composes well known widgets" because then there's a chance I could just use this to generate a presentation layer and integrate it instead of new blobs of code I need to essentially reverse engineer or remake.
