Kai's verdictS-tier inside Photoshop (Generative Fill). B-tier standalone.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
