Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
