Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.
