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.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
