Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
