I understand (also by reading your other responses here). Very nice, I like it. Is the summary feature based on one article (the top one mentioned), or does it combine all articles on that topic? And any roadplan for a native iOS app?

Summaries are done for a single article. I think it's better this way — a summary is a clear reflection of an underlying article, where all statements can be easily tracked to a single original source. That makes LLM hallucinations extremely rare.

No plans for an iOS app, but my site is a PWA so can be installed and look like an app both on Android and iOS.
