Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
