It was similar to the AI art generators, except it replicated voices from a dropdown list of characters and made them say whatever you typed for the input. It had Ben Shapiro and I believe Joe Rogan as options. I'm like 99% sure the link was posted somewhere on hexbear, less certain on which comm but I think it was this one. The link was in a comment, and I believe there was another comment to that one where the user said they made Ben Shapiro say something wacky.

mods feel free to delete, but know that I've been searching for hours and WILL engage in protracted person (me) war on c/art if I don't find it
