Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for model-shopping. I use this for every prototype before committing.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
