Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
