Photoshop's Generative Fill feature is CRAZY. Simply select part of the picture where you want something, and then type a few words to describe what you want there. Photoshop reads the worse and generates 3 options and blends what you described into your image.
It's not perfect today - it's still just a beta. But it's REALLY good and I'm sure it's going to get better. I show you how to use it as well as some weaknesses - like many different things are blocked by Photoshop for violating its terms of use.
Generative Fill is only currently available in the Beta, but I think all Creative Cloud subscribers have access to it.
