What Book AI provides

Book AI: Story Generator lets you create books from your ideas, read them chapter by chapter, and download them as PDFs. You can choose a genre, a suggested reader age, the chapter count, and whether to include illustrations for the cover and every chapter. You can also explore the sample books included in the app.

By using Book AI, you agree to these terms. If a feature or condition changes materially, we will update this page and its effective date. The app is distributed through the relevant stores and is also subject to their terms.

Your account and guest access

You can continue as a guest or sign in with Apple or Google. Your chosen name appears in your reading experience. Do not share account access or impersonate someone else.

A guest account depends on the session stored on your device. If you uninstall the app, erase its data, or lose the device before linking the account to Apple or Google, you may be unable to recover its books or coins. You can delete your account in Settings.

Your ideas and AI results

You decide which prompts to submit. Book AI uses AI providers to produce text and images, so an output may contain errors, repetition, or unintended similarities to other works. We do not guarantee that a story is unique, accurate, suitable for every audience, or fit for a particular commercial use.

You can read and download the books you create. Before publishing, selling, or sharing a result, review it and make sure you have the necessary rights to names, characters, trademarks, images, and any other material you asked to include. Naming a familiar character in a prompt does not grant a license to that character.

The Book AI name, mascot, interface, and included sample books and illustrations remain with their respective rights holders and are not transferred by using the app.

Responsible use and reports

Do not use the app to request illegal, deceptive, abusive, or rights-infringing content. A request may be rejected by our rules or an AI provider's rules. If a book or ad seems inappropriate, use the report option in the app or contact us.

We may limit access when needed to protect the service, investigate abuse, or meet a legal obligation. We review reports and take appropriate action based on the circumstances.

Coins and in-app purchases

Creating a book uses coins. Before confirmation, the app shows the coin cost of your choices; more chapters or illustrations can increase that cost. Coin packs are one-time purchases, not subscriptions, processed through the Apple or Google store. Prices, taxes, and refund requests are handled by the store where you purchased.

Purchased coins do not expire while you keep your account. They are not cash, earn no interest, and cannot be withdrawn or transferred to another person. If you paid but the coins did not appear, contact us with purchase information, without sending complete payment details.

Rewarded ads

Watching an ad to earn a coin is optional. A reward is credited only after you complete the ad and the provider confirms it. Currently you can earn at most one coin every 24 hours and 15 ad-earned coins over the lifetime of the account. Ad availability varies by region, device, and provider.

You do not need to watch ads to read sample books or spend coins you already have. You can report an inappropriate ad from the Coins section.

Failed generations and availability

Creating a book can take time and relies on external services. If a request fails after coins were reserved, the system returns the coins for that creation and shows an error. A request rejected by content rules may also require you to change the description before trying again.

We work to keep Book AI available, but we cannot promise uninterrupted operation or an exact generation time. AI, illustrations, purchases, and ads may be affected by your network, the stores, or service providers.

Downloads and deletion

You can download a book as a PDF from its options. A file you save or share outside Book AI remains under your control; deleting the book in the app does not automatically erase those copies.

When you delete a book or your account, associated content is removed from our systems as described in the Privacy Policy. Deleting your account also ends access to its coin balance and library, so download any books you want to keep first.

Changes, license, and contact

These terms may be updated to reflect changes to Book AI, its providers, or the law. The date above identifies the current version. On iOS, your use of the app is also subject to Apple's standard end-user license agreement, linked at the foot of this page.
