Kai's verdictA-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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for realtime. If latency matters more than voice catalog, start here.
