Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier in its category. The first AI music tool I'd actually listen to.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.
