Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.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.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
