Q: Clarification on Book Creation vs. Book Project and Language Limitations
Good morning,
I'm not entirely clear about the difference between book creation and book project creation. My intention was to activate Tier 4.
One essential point I only understood by reading other users' questions and your replies is this: “it only writes books in English.”
Does the tool really generate content exclusively in English?
I'm surprised that such an advanced system could be limited to a single language. Does this mean that authors writing in Italian cannot use it effectively? Or would the result simply go through automatic translation, with no attention to style or content quality?
Thank you for your attention.

Thanks for your question—and for considering Tier 4!
To clarify: each book project begins with a book outline, and you can create as many outlines as you like before deciding to move forward. Once you’re happy with the structure, you can generate either a book blueprint (the first part of each chapter, with writing prompts and tips) or a full book. Just keep in mind that once a blueprint or full book is generated, it counts toward your plan and can’t be changed or re-used—so we always recommend perfecting the outline first.
And yes, First Book ai currently supports English only. Our model is built specifically for creating coherent, structured business books in English. We understand that might be a limitation for some, and we’re always grateful for feedback as we continue developing the product.
If you have any questions or need help getting started, feel free to reach out—we’ve helped hundreds of first-time authors bring their book ideas to life, and we’d love to support you too.
Best regards,
Casper
