Kai's verdictS-tier for solo + free. The best free option, hands down.S-tier in its category. The first AI music tool I'd actually listen to.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
