Kai's verdictS-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.
