Interesting. It appears this doesn't use AI itself (though it's probably vibe coded). Figma in dev mode already gives react components and css styles [1] and this seems like a more automated way to pull that functionality. It's unfortunate figma paywalls dev mode and this might be a good way to work around the limitation.
I wish you luck with your project.
