Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. S-tier if you self-host. The reason open-source image gen matters.
