A: Hi there,

Thanks for your question! Currently, First Book ai supports English only. We’re focused on helping users create professional business books in English with clear structure and coherence.

If you'd like to see how the process works, you're welcome to create unlimited book outlines before deciding to generate your full book. This way, you can test and refine your ideas without using your book credit until you're fully satisfied.

If you have any more questions or need help, feel free to reach out to us at hello@firstbook.ai — we’d love to support you!

Best regards,
Casper

Q: Being asked to pay more after trying to generate my book

I need help, I have Tier 4 and when I generate the book I am being asked to pay another $249 for my manuscript.

Shouldn't my Tier 4 cover that?

A: Hi there,

Yes, it does cover up to 10x full books and 10x book blueprints each month. Unless you've used all credits.

Please, send us an email at hello@firstbook.ai so we can look into it right away :)

Q: The video specifically says "Business" books... can this do other things?

If I wanted a history of the battle of waterloo, or a biblical exegesis of the prophecies of Daniel 7 in the old testament, could it do those things, or is it ONLY business based?

A: Great question — and thanks for asking!

First Book ai is built specifically for business books and practical non-fiction, which is where our structure and AI perform best. That includes topics like leadership, strategy, entrepreneurship, marketing, personal development, and similar areas with a professional or educational angle.

While you might be able to guide the tool toward something like historical analysis or a light theological overview, we don’t recommend it for deep historical research or religious exegesis — especially when accuracy, interpretation, and sourcing are critical. It’s not designed for academic or heavily analytical content outside the business/non-fiction realm.

That said, you can create unlimited outlines before committing to generating your book — so you're welcome to test your topic and see if it fits within the framework!

If you have a project in mind and want input, feel free to reach out to us at hello@firstbook.ai — happy to help.

Best regards,
Casper

Q: Language specific searches.

Hi there🙃 . Just a quick Q in here even if I've already bought my tier. Is it possible to ask the generator to search for info in a specific language first, t.ex. German or Swedish even if the output will be in English?

A: Hi there!

Thanks for the question — and great to hear you’ve already grabbed a tier!

At the moment, First Book ai only works in English and doesn’t support language-specific research or inputs in other languages like German or Swedish. All content is generated based on English-language prompts and training.

That said, you’re welcome to include ideas or references from other languages in your outline, and we’re always looking at ways to expand the platform — especially as more users from around the world join in.

If you have any other ideas or feedback, feel free to reach out to us at hello@firstbook.ai — we’d love to hear from you.

Best regards,
Casper

Q: Question: Extra languages including Turkish?

I read about expanding your platform with more languages other than English. Is Turkish on your list? Any expected date?
