Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier if you already pay Gemini. B-tier standalone.
