Kai's verdictA-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-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 inside Photoshop (Generative Fill). B-tier standalone.
