Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.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.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
