I did something similar, but with a chrome extension. Basically, for every web page, I feed the HTML to a local LLM (well, on a server in my basement). I ask it to consider if the content is likely clickbait or can be summarized without losing too many interesting details, and if so, it adds a little floating icon to the top of the page that I can click on to see the summary instead.
My next plan is to rewrite hyperlinks to provide a summary of the page on hover, or possibly to rewrite the hyperlinks to be more indicative of the content at the end of it(no more complaining about the titles of HN posts...). But, my machine isn't too beefy and I'm not sure how well that will work, or how to prioritize links on the page.
