Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for creators training custom looks. B-tier for general use.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
