GenUI isn't about designing cosmetic "skins." (Usually, anyway. I guess it could be used for that)

It's generally for letting users customize the own workflows. How many times have you, or one of your users, liked a piece of software because it mostly fits an existing workflow but that remaining 20% is an annoyance, or maybe even a dealbreaker?

This is probably more common for businesses. They have existing procedures. and they want your software to fit into their existing processes and workflows... not the other way around.

GenUI is far from a one size fits all approach or magic bullet, but it can address a lot of those situations that either would have been dealbreakers, annoyances, or change requests. I suppose it can also help with user retention; once they've put the time and effort into customizing your product they theoretically are less likely to switch to a competitor.

Existing OpenAI/Anthropic models seem to already handle this pretty well. As you might expect, letting users describe their own UI is pretty easy. The hard part is making it work and making sure they don't escape their sandbox...

As a user, most GUIs are awful. I’m fairly certain that this thing could, for example, vibe up a better UI for Amazon Music in less time than it takes me to find the music I’ve purchased and downloaded (because the system is more interested in funneling me toward a streaming subscription that I don’t have).

Of course pushing users toward subscription services they don’t need is part of the design goal. So I guess something where the user vibecodes up their own UI will not become standard. But we can dream.
