Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
