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
