Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
