I Built a Chat App That Rewrites Its Own UI in Real Time

So I had this idea that kept nagging at me.

Every AI chat app works the same way. You type something, the model returns text or markdown, the UI renders it as a nice formatted paragraph. That is fine if you want an answer. It is genuinely boring if you want to actually build something.

What if the AI could respond with a working game board you could click? What if saying "make it Barbie themed" actually transformed the whole interface while you watched? What if "add a starfield in the background" dropped an animated canvas behind your chat in real time?

I spent a few weeks building exactly that. I call it FlowChat.
