Yes, that’s true! I have used one. If you want to try looking at how such applications function, https://undress.app/ is one of them and I would recommend it. It is much better than I thought it would be. I used it for certain candid pictures, and it was quite shocking to see how real some of the outputs were, though I mostly used it just for fun. It’s a good application in case one loves playing with out-of-the-box photo techniques!
