Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.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.
