Ironically that's an AI tool I would use - one that can dynamically filter content from sites according to my preferences, to counter the algorithmic spam. It wouldn't be generative AI though, and that's the only kind of AI that matters right now apparently.
Could be a good use of structured output, Llms work okay as one shot classifiers, you could define a schema that's just like, array[]{xpath:true/false} and tell the bot what you want to see and what you don't want to see.
It's very easy though, Right click > Block element > Create. Overlays show which blocks you are removing. Sliders can be used to increase/refine.
How can we make it even easier and visual? Customizing pages by removing elements should be part of the default browser experience to be honest. Like in the initial web where you would tweak the color of links, visited links, etc.
Information hygiene is a skill which started out important but is going to become absolutely critical.
