It was basically exactly Reddit but with two noticeable AI features that were easy to ignore:

1. An AI-generated summary of popular posts on the homepage
2. Underneath every link post to an article was an AI summary, but on the app it was a collapsible section so collapsing it in one post would keep it collapsed for all.

I found the second one slightly handy, though, because when I was on Reddit I fell into the bad habit of posting after just reading headlines. With the AI summaries I could get more context and it often lead me to opening more articles than I would have without it.
