Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-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.
