Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
