You can check out www.nooshub.com (disclaimer: I created it...)
It takes all the news in your feeds and finds similar articles. Turns out that important news are covered by all the different news outlets, and these news are then presented as top news. And there is also a special page called "nutshell", where only top news of all your pages are presented.
For example two current top news on the "International News" page would be "Nobel Peace Price" and "Instagram down again", on "Technology" it is "Chrome Attempts to Resurrect RSS" (coincidence), "Nintendo Switch", and also "Instagram down"...
Thank you for replying. Personal non-generated replies are a major booster for my interest and support. I remember bringing this up back in the day and it's still present. How should I expect this feed to look?

I see an image on the right (nice). A headline (good). And this type of text.

Checkout https://www.nooshub.com/pages/1332-neo-news, should be exactly what you are looking for: hot topics are at the top of the feed, you can use your own RSS feeds and configure the algorithm for identifying similar news! Preview currently only available when logged in, but some put the whole article in the RSS feed, then you can read it in the reader without distraction. I am not a fan of fetching full content from a newspaper, as in the long term you cut off the hand that feeds you (“feeds” 🙃)
Forgot to mention - If you like please have a look at "News International" https://www.nooshub.com/pages/7-news-international, that is "how it's meant to be" - multiple related feeds on a page and similar articles grouped together..
If you really just want the separate feeds with all the articles, I admit there are definitely better options..
There is nooshub, but it costs 20$/year. Does anyone know similar software available for free or open source?
It would be rather easy to create an RSS reader which clusters news based on similarity (hierarchical clustering would be the best option probably here). If someone is interested, just write to me!
