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. S-tier if you self-host. The reason open-source image gen matters.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
