Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-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.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
