Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for model-shopping. I use this for every prototype before committing.
