Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for model-shopping. I use this for every prototype before committing.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
