Kai's verdictS-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. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
