Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for open-source model APIs. The default in this space.
