Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for designers. The only one that takes vectors seriously.S-tier for model-shopping. I use this for every prototype before committing.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
