As a UI engineer, this terrifies and excites me at the same time. 🫠
Thesys
Haha @vikasraok. No need to be terrified. C1 is only here to supercharge your frontend development.

@yulia_kuznetsova3 yes this setups groundwork for building AI native experiences.
Thesys feels like a generational leap in UI — where design stops being static and starts being truly generative.
The product is so cool👍
The product looks great. I created account in your app, where to apply the coupon code to claim "5M tokens", I don't see any option there.

@vigneshchinnadurai You'd have got free credits by default when you signed up. Can you please check?
