Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
