Writing a Book with AI in 2027: KDP's AI Rules, Quoted and Explained

Can you write a book with AI and sell it on Amazon? Yes. KDP allows AI content, but it draws a hard line between AI-generated and AI-assisted work. If an AI tool created the actual text, images or translation, you have to disclose it when you publish, even if you rewrote much of it afterwards. If you wrote the book yourself and used AI only to edit, polish, error-check or brainstorm, there is nothing to disclose. This guide quotes KDP's rule in full, sorts common situations into a table, compares Apple Books, Draft2Digital and Google Play Books, explains the current weekly title limit and sets out where US copyright law stands. Everything here reflects the rules as of November 2026. Still choosing a tool? Our guide Best AI for writing a book compares what each one produces and how you pay.

What KDP's AI policy actually says

The rule sits in KDP's Content Guidelines, under "Artificial intelligence (AI) content (text, images, or translations)":

"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 cover and interior images and artwork. You are not required to disclose AI-assisted content."

KDP then defines the two terms:

"AI-generated: We define AI-generated content as text, images, or translations created by an AI-based tool. 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: If you created the content yourself, and used AI-based tools to edit, refine, error-check, or otherwise improve that content (whether text or images), then it is considered "AI-assisted" and not "AI-generated." Similarly, if you used an AI-based tool to brainstorm and generate ideas, but ultimately created the text or images yourself, this is also considered "AI-assisted" and not "AI-generated.""

The section closes with a sentence that applies either way: "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."

Three consequences follow straight from that wording, and authors miss them all the time:

1. Heavy editing does not change the label. An AI draft you rewrite line by line is still AI-generated as far as KDP is concerned.
2. Translations count. If an AI translates your English book into Spanish, the Spanish edition is AI-generated.
3. Republishing triggers it too. Edit an existing book, add AI-generated material and republish, and you need to disclose again.

AI-generated or AI-assisted? Common cases

The last row is a gray area. The policy talks about the content of the book, not the product description on the store page. If you want to be safe, disclose. Answering "no" when the honest answer is "yes" is the bigger risk.

How many books can you publish per week?

You will still read that KDP allows three new titles per day. That limit came from a KDP announcement in September 2023 and no longer applies. KDP Help now lists two weekly limits:

In KDP's words, the limits "apply separately to each book format (eBook, paperback, and hardcover), and reset every Sunday at 12:00 AM Coordinated Universal Time (UTC)." Updates to titles you already submitted do not count. KDP has changed these numbers more than once, so check the help page before you plan a release schedule for a series.

Will readers see that your book was made with AI?

On KDP, the disclosure goes to Amazon: the policy asks you to "inform us." Nothing in KDP's published documentation says the answer appears on your product page, and KDP does not ask for a note inside the book.

Apple Books works differently. Its Store Formatting and Content Guidelines (item 1.13) call content AI-generated when "a material portion of the content is generated by an AI-based tool as opposed to a human author or illustrator." Such books must use the "AI Generated by" contributor role and state the AI-generated creation method in the description, so customers can see it. AI-assisted content needs no disclosure at Apple either, and Apple explicitly includes "idea generation, research, editing, or producing cover images for a book composed by a human author or illustrator."

How other stores handle AI books

Draft2Digital is the strictest of these: "While we support AI-assisted content we do not accept content that has been generated entirely by AI/LLMs that has not gone through extensive editing from a human." It also says it is not a destination for "mass production book farms." Google's content policies do not mention AI, but they rule out "gibberish, nonsensical, or repetitive text that provides no narrative or educational value", which is exactly what low-effort AI books tend to produce.

Can you copyright a book written by AI?

This question has nothing to do with the KDP checkbox. KDP asks how the content was made. Copyright asks how much of it came from you.

The US Copyright Office set out its position in registration guidance published in March 2023: "If a work's traditional elements of authorship were produced by a machine, the work lacks human authorship and the Office will not register it." The same guidance says that when an AI receives "solely a prompt from a human" and produces a complex written work, the traditional elements of authorship are "determined and executed by the technology", not by the person who typed the prompt. When you register a book that contains more than de minimis AI-generated material, you have to disclose it and exclude that material from your claim.

The Office's January 2025 report on copyrightability goes further on prompts: "Based on the functioning of current generally available technology, prompts do not alone provide sufficient control." It also confirms what remains protected: "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."

The courts agree on the baseline. In Thaler v. Perlmutter (March 18, 2025), the D.C. Circuit held: "As a matter of statutory law, the Copyright Act requires all work to be authored in the first instance by a human being." That case involved a work with no human contribution at all; how much human input is enough is decided case by case.

What this means in practice:

• The more you write, rewrite, add and rearrange yourself, the more of your book is protected.
• AI text you publish unchanged can be copied by others, and copyright gives you little to stop them.
• Keep your drafts, notes and versions. If you ever need to prove what you contributed, they are your evidence.

Rewriting will not move a book from "AI-generated" to "AI-assisted" on KDP. It does decide how much of the book you own.

Selling in the EU: the AI Act

If you publish for European readers, Article 50 of the EU AI Act has applied since August 2, 2026. It requires anyone who publishes AI-generated text "with the purpose of informing the public on matters of public interest" to disclose that it was artificially generated, unless a human has reviewed or edited it and someone holds editorial responsibility. According to the European Commission's FAQ, spell-checking or grammar correction alone does not count as human review. A novel or a gardening guide usually does not inform the public on matters of public interest; a nonfiction book on current political events might. Realistic AI images of real people, places or events (deepfakes) carry their own disclosure duty. This guide is not legal advice; for a sensitive nonfiction title, ask a lawyer.

A checklist for publishing an AI-written book

1. Record how the book was made. Note which parts an AI generated: text, chapters, translation, cover, illustrations. That tells you what to disclose on each store.
2. Disclose honestly. On KDP when you publish, on Apple via the "AI Generated by" role and the description, and again whenever you republish with new AI material.
3. Edit it yourself. Not for KDP's label, but for quality and ownership: read every chapter, add your own examples, cut repetition. Draft2Digital requires it.
4. Check the facts. AI sometimes invents numbers, sources and quotes. Health, legal and financial topics need an expert review.
5. Check third-party rights. Titles, covers and characters must not borrow other people's trademarks or works. KDP puts that responsibility on you, however the content was made.
6. Plan your uploads. With 2 new titles per format per week, a series will not go live in one week. Stagger the formats.

How Bookfairy's tools fit the KDP rules

Bookfairy is a toolkit for self-publishers by Orbita Media GmbH. Some tools generate content, others check your own writing. Here is how they map to KDP's categories:

The Write the whole book tool writes how-to guides and nonfiction, not novels. You read the outline and the complete first chapter for free before you pay; a full book starts at $58.80490 tokens. Because the text is AI-generated, you disclose it on KDP, and your own revisions strengthen your rights to it. If you write the book yourself and only use the editing tool, your book stays AI-assisted.

Which features use AI, where their limits are and what to label when you publish is set out in our AI transparency notice. The platforms' current guidelines always take precedence; KDP updates them regularly.
