Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for designer-led sites. S-tier if animations matter.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for model-shopping. I use this for every prototype before committing.
