Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
