What I like is the philosophy: use an LLM as a personal filter based on a plain-text description of your interests. No training a recommendation algorithm on engagement signals. No black-box "for you" feed. Just "here's what I care about, show me relevant stuff." The pattern of "LLM as personal curator" seems underexplored.
It would probably work as a browser plugin, but I didn't have a real solution for rewriting whats on say the reddit or Twitter phone apps.
Probably pretty easy to vibe code up such a thing now.
