And if you crank it up enough, it becomes like a Snapchat filter for your voice.

That was in fact the initial idea behind it and it was used like that for some time (pitch correction only) until Cher came along and started that stupid trend of deliberately misadjusting the plugin to make the voice sound super unnatural. I will never understand how that awful sound could become the norm and ruin so many genres all over the world. To me, even after all those years of this shit being normalized, it still just sounds like someone fucked around with the autotune setup.
