Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier in the agent category. The first one I'd give to a non-technical friend.
