Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-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. The most interesting spreadsheet in years. Great for ops dashboards.
