I paid 10.00 and on the same day I cancelled my subscription. After providing me with a summary of a specific book, it also gives me the 10 main quotes from the book. I purchased the book from Kindle, so I tried to match the quotes given by booknotes with the Kindle book, and none of the quotes are on the book. In other words, booknotes created the quotes... If the quotes are fabricated by AI, what else in the summary is also not accurate? I still want to give this site the benefit that they will get it right, but right now, I cannot recommend it as a reliable tool.

It seems to be working fine right now. Maybe try again and double check if you’re using the book’s original or most recognized title. That might make a difference.
