After 25 years of building web frameworks at Vaadin, we asked: what if the AI is in the driver’s seat? Would we even need a UI?

In Computer–Human Interaction (CHI), the AI runs a business process. When it needs something from a human, it creates a purpose-built UI in real time, adapting as you interact.

No code. No pre-built app. Just AI “speaking” in UI.

Questions for HN: • Best use cases you can think of? • Which AI models would work best for this? (everything we’ve tried so far is either too slow or too dumb) • If CHI creates something innovative, please share the link to prompt here (you can copy it from the demo after it yields results)
