When I link it to a well known piece of text, does it go to its wikipedia page (or something of the sort) and summarize that, instead of analyzing the actual text?

For example I linked to Thus Spoke Zarathustra by Nietzsche - I got a summary that highly resembles something a wiki page would say about the text and quite unlike what I'd expect from reading the text itself.

I've gotten a very similar feeling giving it Plato's Republic.

Update: I've linked it to The Idiot by Dostoevsky and it didn't do well at all. Strange piece of technology - reminiscent of ChatGPT.
