I think this wull be the future of UI! Traditional UIs will transition to chat based tools with enhanced UI components.

@madalina_barbu Thanks! Would love for you to try it out.
Interactive UI is a big leap. How do you ensure consistency so the same intent doesn’t produce wildly different interfaces across runs?

Congrats on the launch!!
This is interesting. Generative UI instead of static text feels like the natural next step for LLM-based apps.
