Book difficulty website

I remember a website shared on here some time ago about a website where it ranked all the books by difficulty and you could access word lists as needed for them. Anyone remember what that was called? It had a solid list of books and gave them all pretty good level analysis.


Is this it?

I’m not sure if there are word lists on this site though, sorry. I haven’t used it before.
