Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Still early. Manus is more flexible for less money.
