A_No_Name_Mouse

HN is a great source of news. Not every subject is of equal interest to everybody though. Ideally I would like to have a personalized feed of submissions that may interest me, with a short summary of the linked article.

I now use the RSS feed of new submissions to automatically filter posts on keywords in the title (e.g. "space" but not "SpaceX"). This has the added benefit that niche articles with 0 upvotes will still get my attention. An AI should be able to fairly easily categorize each article so you could filter on category/label instead of literal keywords. This could also address a request often seen on HN "is there an HN focussed on subject xyz", because this way focus can be achieved by means of a filter with HN as the single source. A generated TL;DR would be a bonus.

Knowing the amount of smart and AI focussed people over here, probably someone has already thought about or even implemented this. So what do you think? Ideally this would be a publicly available feature instead of everyone analyzing and filtering articles themselves.

Edit: changed "posts" to submissions to make clear it is about submitted articles, not comments
