Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
