You really know what a good interface should be like, this is really inspiring. So is the design of everything I've seen on your website!

I won't pile on to what everyone else has said about the book connections / AI part of this (though I agree that part is not the really interesting or useful thing about your project) but I think a walk-through of how you approach UI design would be very interesting!

LLMs are for people who judge books by their covers.

I assume that high-frequency LLM users are functionally illiterate to the extent that the design of a book's cover is genuinely the only criterion they can use to evaluate said book.
