I am sorry you feel this way, I added pay what you want messagesin every button to make it clear, but ill try to rethink if I can do it in a better way. Its kind of hard to know if someone would be willing to pay for the generated books. We didn't had any other ideas how to test that out.
Do you think that paywalling, after seeing cover and first page would be more honest/acceptable? Or maybe we should give some free generations after email confirmation. It certainly something we will be thinking through as we don't want anyone to feel we are being dishonest.
