It's not working that well at the moment
Tried it 2 times to get a book (used another account to test it, but subscribed after that with AppSumo anyway as I guess you guys will handle this within the future). Somehow the chapters and titles within the book are messed up. Probbaly it's better not to serve a Table of Terms. The chapter numbering within the whole book is pretty confusing. Sometimes chapters are made double.
The Translation costs are pretty immensive: "Top-up at least 195.993 credits to translate" It' Even much more as to get a new book. I thin I spent 80K Credits to create the book.
Overall my test: It's not bad and a lot of potentialin it, but at the momen it could not deliver what it promissed. I can't test any furter as I already spend 20€ to extend my credits, but I am not willing to invest more for stuff I can't use and help you to get your product up running ;)

Edited Oct 29, 2025Hi, thank you for the review and for reaching out through support. We will add a more detailed reply here as soon as we get a more clear picture of the toc issues you mentioned with some examples. We could not quite identify what the issues are but we will with your help over the support channel.
On translations, they are actually not part of the service and will be retired soon for the reasons you mentioned. They are not included in the Appsumo plans or the subscription plans.
To make it clear, youbooks supports generating new books in non-english languages. Translating a book is a different service though.
