Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
