Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
