Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Still early. Manus is more flexible for less money.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
