I'd be interested to read more about it, as I believe that I have the same problem and I am also trying to remove reddit from my life.

I think that a carefully designed solution using LLMs could be the way, if it could correctly filter what I'd still want to read. I'm not sure that a browser extension is the way since it could too easily pull me back to the website. But I haven't really tried any solution like that for now, except for the simple keyword filters in RES.

For now, I'm using Cold Turkey to block some news subreddits, and News Feed Eradicator to remove all feeds. I can still visit specific subreddits and read threads. I don't think that's the right solution, but it helps me notice my patterns.

In any case, if you're interested in collaborating on this, let me know. It could be an interesting little project to work on.
