Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier in its category. The first AI music tool I'd actually listen to.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
