If anyone wants to build this as a freelance project, email me (email in profile), I'll hire you to make it.
Some things I'd like with it:
1) Rewrite everything on a webpage in a peaceful and neutral tone
2) Rewrite everything on a webpage to be assertive/direct, instead of passive aggressive (e.g. lots of negative comments could be replaced with simply "I don't like this" or "I want other people to know I dislike this and agree with me")
3) Add emojis inline in text so that pages are easier to skim
4) Add topic based filters/flags/emojis so I can highlight things that I care more and less about
All of them would be toggleable, of course.
