Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier if you already pay Gemini. B-tier standalone.A-tier in its niche. The only one that actually gets emotion right.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
