Its pretty easy to do the user-loyal bit, with a bit of prompting to give an llm your preferences/profile. Not ideologically loyal, but i mean acting in accordance with your interests.

The tricky part is having that act across all sites in a light and seamless way. Ive been working on a HN reskin, and it only is fast/transparent/cheap enough because HN has an api (no scraping needed), and the titles are descriptive enough that you can filter based on them, as simonws demo does. But its still HN specific.

I dont know if llms are fast enough at the moment to do this on the fly for arbitrary sites, but steps in that direction are interesting!
