Very nice tool with only a bit improvement

I found First Book ai very useful. The create a first version of a book is very easy and a step-by-step approach. I really like the output (round about 150 pages) in Google Docs.

I definitely will keep my highest tier because I see a lot of potentials

What I have to check for me / feedback:
- the text is sometimes very identical and sometimes I think, I just read this
- there is not much flexibility in giving AI more instruction, but some fields are there
- More chapters / subchapter (or even to control the existing ones) would be nice
- other languages (like german) would be great. How ever, a translation bei ChatGPT was quite good.

So this tool helps me to get rid of the blank paper and at some points I have to improve it. Keep up the good work!

Amazing tool

I am an engineer in the education field and today I bought Tier 4, because at my university we need to create lots of publications, I see that this not only provides a great result in creating books in a few minutes. I must say that this is not ChatGPT - it is something authentic and incredible. The only thing you should take into consideration is to provide other languages, I'm Ecuadorian, so spanish would be great fit as a second language. At the same time, I see that in terms of code, it doesnt generate an image or coding, but it could be soemthing you could update. That would be a great help. I like also that you can download your word document and refine according to your experience or maybe adding an image that relates to the content. I really like it. Hope you can consider my suggestions and I see lots of potential to this tool. I tell you this, beacuse I payed to a person to create a book and it has passed more than year and a half and the book is not published yet. So thank you so much, but please keep improving with the recommendations of the users.
Another detail to consider is to enable the citations in APA, IEEE, Vancouver formats because that will give sustain or relations to authors that have given maybe the same idea and the book provides this type of references at the end. It should be a great improvement.

🔥 This Bookwriter is EPIC! 🔥

If you're even thinking about publishing a book, get Tier 4 before they change their mind! Trust me—I’ve got three books on Amazon, and this is the real deal. Any other tier just doesn’t make sense unless you're only looking to slap something together fast to be called a one time author.

But this? This doesn’t look like AI at all. It’s sharp, professional, and exactly what you need if you want a high-quality result. Don’t overthink it—go Tier 4 or go home.

No Pulitzer but there is hope

I am underwhelmed after having generated my first book. I still get a certain "Wow sensation" when working with AI so I was excited when I downloaded my book.

It came out to 162 pages (way too many) and most of the pages were very similar. I didn't read the whole book but every paragraph that I did read sounded like versions of the same paragraph over and over again.

I tried to prompt with a clear and systematic approach but I don't think there were enough questions to properly guide the writing. I think each chapter and sub-chapter should have had it's own prompt.

The final book will require a lot of editing. So much in fact, that I will scrap the entire book and write it with Claude.ai instead.

I wanted to like First Book AI but for $49 it just wasn't worth it for me. There are better AI tools out there that give you much more flexibility.

/R

****
PS: I was surprised that the limit of 8 chapters and 3 sub-chapters was in fact a requirement and not a limit. I tried to submit a shorter outline but I got the following email.

"The outline does not meet the criteria because Chapters 3 and 5 each have only 2 subchapters instead of the required 3. Could you kindly adjust it to 8 chapters, each with 3 subchapters, and re-submit it for review?"

Hi there,

Thanks for taking the time to share your experience — even if it wasn’t what you hoped for. I really appreciate the thoughtful feedback.

You’re right that our structure is currently fixed at 8 main chapters with 3 subchapters each. This framework is in place to ensure the AI can maintain a strong, coherent flow throughout the book — something we’ve found to be crucial when generating...

First book

Well, i was so excited to try, inserted 2 chapters ( even though i had almost all chapters ready), i didn't find button to add more text or edit and... book went to production! I could not catch it. Of course it was all mechanical. Due to lack of information .The fact that i can't edit before i want to publish make it hard. I have only 2 books ( still don't understand 2 books for life of membership?) Even though i got my first book reversed and i can start all over, but now i hold till i make entire book before i submit. If you ask me what would i like to see- it's after table of content i would like to have 1 chapter at the time. Maybe discuss which chapter should go first, some options i would say Maybe draft or test option . NOT ENOUGH BUTTONS!
All black or white. made by man for sure LOL

Hi ogallery,

Thanks for sharing your experience — I’m really sorry it felt confusing and rushed. That’s not the experience we want for anyone.

Just to clarify for others reading: You don’t need to add any chapters manually. The process starts with creating a book outline, and from there, you can choose to generate either a Book Blueprint (which gives you the first part of each chapter and tips...
