Can I legally publish and sell a book written by AI?

The short answer, in three parts

• Publishing and selling: allowed. A book written with AI is subject to the same rules as any other book: it must not copy someone else's work, defame a real person or pretend to be by an author who did not write it.
• Amazon KDP: allowed, with a declaration. KDP requires you to tell it about AI-generated text, images (including the cover) or translations when you publish or republish. AI-assisted work, where you wrote it and used AI to edit or brainstorm, does not need to be declared.
• Copyright: partly. In the US, text generated by AI from your prompts is not protected by copyright. Your own writing, your creative edits, and your selection and arrangement of the material can be.

What the US Copyright Office says

On 29 January 2025 the US Copyright Office published Part 2 of its report on copyright and artificial intelligence, on copyrightability. Its conclusions, in its own words: "Copyright does not extend to purely AI-generated material, or material where there is insufficient human control over the expressive elements." "Based on the functioning of current generally available technology, prompts do not alone provide sufficient control." And "Human authors are entitled to copyright in their works of authorship that are perceptible in AI-generated outputs, as well as the creative selection, coordination, or arrangement of material in the outputs, or creative modifications of the outputs." Whether a particular human contribution is enough is decided case by case.

The Office applied the same idea before the report. In February 2023 it reviewed Zarya of the Dawn, a comic book whose images were made with Midjourney: it found the author owned the text and the selection, coordination and arrangement of the text and images, and that the Midjourney images themselves were not the product of human authorship.

The courts have agreed that an author must be human. In Thaler v. Perlmutter, the US Court of Appeals for the D.C. Circuit upheld on 18 March 2025 the Office's refusal to register a work listing an AI system as its author, and on 2 March 2026 the Supreme Court declined to hear the appeal (docket 25-449).

If you register a copyright, the Office's 2023 registration guidance says you have a duty to disclose AI-generated content that is more than de minimis, to exclude it from your claim, and to describe what the human author contributed. It also says not to list an AI tool or the company behind it as an author.

What that means for a book you sell

Copyright is not a licence to sell. It is the right to stop other people copying. You do not need a copyright registration, or even copyright, to publish a book and sell it. What you may lack, for the parts the AI wrote on its own, is the power to stop someone else reprinting them.

That is why your own work on the book matters. Rewriting passages, cutting and reordering chapters, adding scenes in your own words: under the Office's conclusions, that is the part copyright can protect. If you expect to rely on copyright, keep the drafts that show what the AI produced and what you changed. The Office looks at exactly that kind of comparison.

Amazon KDP's rules for AI-generated books

KDP's content guidelines have a section on AI content. The key sentence: "We require you to inform us of AI-generated content (text, images, or translations) when you publish a new book or make edits to and republish an existing book through KDP." AI-generated images include the cover and interior images.

KDP draws the line this way. AI-generated: "If you used an AI-based tool to create the actual content (whether text, images, or translations), it is considered 'AI-generated,' even if you applied substantial edits afterwards." AI-assisted: you created the content yourself and used AI to edit, refine, error-check or improve it, or to brainstorm ideas; "You are not required to disclose AI-assisted content."

KDP also puts the legal responsibility on you: "You are responsible for verifying that all AI-generated and/or AI-assisted content adheres to all content guidelines, including by complying with all applicable intellectual property rights." The same guidelines forbid a description meant to mislead customers or that does not accurately represent the content of the book.

There is also a limit on how many new books you can add. KDP's Create a Book help page now states: "Creation limit: Up to 2 titles per book format each week" and "Submission limit: Up to 2 new titles per book format each week." The limits apply separately to eBook, paperback and hardcover, updates to books you have already submitted do not count, and both reset every Sunday at 12:00 AM UTC. The daily cap KDP lowered in September 2023, reported at the time as three new titles a day, is not what the help page states today.

Can I sell a book I wrote with ChatGPT?

Yes, under the same three checks. First, the terms of the tool you used: OpenAI's terms of use say that, as far as the law allows, you own the output. Read the current terms of whichever tool you used, since they change. Second, copyright law, as above: text ChatGPT wrote from your prompts is not protected in the US; what you wrote or creatively changed can be. Third, the store's rules: on KDP, chapters ChatGPT drafted are AI-generated and must be declared, even if you edited them heavily; a book you wrote yourself and only polished with ChatGPT is AI-assisted and does not need declaring.

What can still go wrong

• Resemblance to an existing book. AI can produce text that resembles something already published. KDP's guidelines put the responsibility for intellectual property on you, and so do our own terms.
• Real people. A novel that names real people can still defame them or invade their privacy, whoever wrote the sentences.
• Someone else's name. In August 2023, books that the writer Jane Friedman said were AI-generated were sold on Amazon under her name, and were taken down after she made it public. Using a real author's name on a book they did not write is a problem with or without AI.
• Misleading listings. KDP does not allow a description that misrepresents the book. A book written by AI should not be presented as something else.

Outside the US

This page covers US copyright law and Amazon KDP's rules. Who counts as the author of AI-written text is decided by each country's own law. In Israel, for example, as of 31 October 2026 we found no court ruling or statute that decides it. If the book matters commercially, ask a lawyer in the country where you will sell it.

Where Write Book fits

Write Book writes a whole long-form novel, 100 to 400 printed pages, from a short description: you approve the plot lines, the chapters are written, and you can edit every line and design the cover. The story is invented prose built on what you tell it. Because the system writes the text, the book is AI-generated under KDP's definition, even after your edits, and you should declare it when you publish. A cover generated by the system is an AI-generated image too.

On ownership, our terms (section 6) say the books you create belong to you, and that you may use them as you see fit, including commercially, publishing, selling and distributing them, royalty-free and without restriction from us. The same section gives Write Book a non-exclusive licence to use the content to run and improve the service, including training its AI models, and says we will not publish your book as an identifiable work tied to you, or sell it to third parties, without your consent. What terms cannot do is create a copyright the law does not grant: the parts you rewrite yourself are what copyright protects.

You get a PDF formatted for Amazon KDP and an EPUB, under any author name you choose. You upload them from your own KDP account; we do not supply an ISBN or run the account. If you have already written the book yourself, manual book mode typesets it and makes the KDP files with no AI touching your text. The first chapter of your first book is free, and the price of each length is on the pricing page.
