Kai's verdict	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.	S-tier for builders. The right primitives. What Kai is built on under the hood.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
