Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
