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

Interactive UI is a big leap. How do you ensure consistency so the same intent doesn’t produce wildly different interfaces across runs?

Savvas Konsta

Cool concept!

Curious Kitty
A lot of “no-code agent” tools break down when you need real integrations, multi-step interactions, and production requirements—what did you deliberately *not* build first (channels, auth/multi-tenancy, exportability, approvals), and how did you decide those tradeoffs?

Congrats on the launch!!

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