I was about to start working on something like this. I would like to try browsing the internet for a day, where all comments that I read are rewritten after passing through a sentiment filter. If someone says something mean, I would pass the comment through an LLM with the prompt: "rewrite this comment as if you were a therapist, who was reframing the commenter's statement from the perspective that they are expressing personal pain, and are projecting it through their mean comment"
I find 19 times out of 20, that really mean comments come from a place of personal insecurity. So if someone says: "this chrome extension is a dumb idea, anti-free speech, blah blah blah" , I would read: "commentor wrote something mean. They might be upset about their own perceived insignificance in the world, and are projecting this pain through their comment <click here to reveal original text>"
