Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in its category. The first AI music tool I'd actually listen to.A-tier for sales teams. B-tier for solo users.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
