Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.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.B-tier. Still early. Manus is more flexible for less money.
