A Cash Grab - Hiked Prices Until After Campaign - $280 to $8 per book
If you purchased this app as an agency .. They were selling a single book at $250+ per book.. post campaign, they are selling books at less than $8 per book... The application is basic and inflexible and the company / seller has made the business value precisely zero with their own 95%+ markdown... avoid

slow and unable to generate a book after hours
I've been trying now to generate a book for a month inside the app. Unfortunately the pages load very slow. To generate the book, you need to complete 4 sections. I've completed them and it continues to say they are incomplete. Restarted the book chapters section multiple times. It says everything is complete and then when I continue to the next section it doesn't acknowledge any of the input. So I haven't been able to generate a book in less than 24 hours - let alone 24 days.

Sep 30, 2025Thanks for the feedback. Of course, it shouldn’t take 24 hours (let alone 24 days) to generate a book. The process is only a few simple steps, and once they’re complete, the book starts generating within minutes.
If something is blocking you, we'd love to take a look at your account. Just reach out to us at hello@firstbook.ai with your account email, and we’ll sort it out quickly.
We’re always...

Awesome Tool for Writing a Book!
I’ve always wanted to write a book about nonprofits and how they differ from regular businesses. After working in this field for over 20 years, I’m particularly interested in demonstrating how these purpose-driven groups can ignite a genuine spark in people’s hearts, unlike private companies, which seem to struggle more to achieve the same.
But I wasn’t sure how to kick things off. When I found First Book AI on AppSumo, I just knew it would click with me. And guess what? It totally did.
No more writer’s block or jitters! My outline is sparking some really thoughtful ideas. It doesn’t do everything for me, and it shouldn’t, but it sure gives me a solid boost!

Amazing Tool for Writing a Book!
For more years that I'd like to admit I've been wanting to write a book, but I didn’t know where to start. Then I found First Book AI on Appsumo, and wow—it made everything so much easier! Their app helps you plan and write your book step by step, and it feels like having a helpful coach right there with you.
The advice and ideas it gives are so simple to follow. It helped me turn my messy thoughts into a real story. Thanks to First Book AI, I was finally able to write the first draft of my very first book! I couldn’t believe it—I’m actually closer to being an author now.
If you’ve ever thought about writing a book but felt stuck or didn’t know what to do, this tool is perfect for you. It’s easy to use and makes writing fun, not scary. First Book AI helped make my big dream finally come true!
I can't wait to publish my book. Thank you, Casper! I should mention you on the Acknowledgements section!
