Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
