Kai's verdictA-tier if you already pay Gemini. B-tier standalone.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.A-tier in its niche. The only one that actually gets emotion right.
