Kai's verdictB-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.A-tier in its niche. The only one that actually gets emotion right.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
