Can you use AI to write a book?

Yes, with care, and with a clear head about what “using AI” means, because that’s where most of the trouble starts.

There’s a big difference between asking a tool to help you think and asking it to write the thing for you. Amazon’s self-publishing platform, KDP, draws that exact line, and the label you land on decides what you have to tell it. If an AI tool created the actual content (text, images or translations), KDP calls it “AI-generated”. That holds even if you went through it afterwards and made substantial edits. Edited or not, it still counts.

“AI-assisted” is the other bucket. That’s where you wrote the content yourself and used AI to edit, refine, error-check or otherwise improve it. Brainstorming ideas with AI counts here too, as long as you ultimately wrote the text. You don’t have to disclose AI-assisted work.

How to do it well

Put AI to work on the scaffolding and keep the prose for yourself. In practice that means brainstorming premises, chapter outlines and character sheets, which are tedious to build and oddly easy to hand off. Research questions you hadn’t thought to ask. Timeline checks, so your hero isn’t at breakfast in two cities at once. And feedback on drafts you’ve already written, which might be the best use of all.

The writing itself stays with you. Partly that’s about the rules (more on those below), but it’s also about the result. Generic AI prose has a tell. It repeats itself, it settles into a flat rhythm, and every paragraph sounds like it was asked to be pleasant. Readers notice. You might not, if you’re too close to it, so read the whole book aloud, start to finish. Repetition and dull cadence jump out when you hear them.

Here’s a prompt for the feedback job. It asks for diagnosis without letting the tool rewrite your work:

Act as a developmental editor. I'm going to paste a chapter from my book.
List any plot holes, continuity problems and pacing issues you find, with a
short explanation of each. Do not rewrite any of the text or suggest
replacement sentences. Only identify the problems.

That last instruction matters. Without it, the tool will cheerfully start “fixing” your sentences, and suddenly you’ve got generated text in your manuscript that you didn’t plan for. (Once the draft is done, editing your book with AI is a much safer job.)

Keep records. If you do use generated text, note what it was and where it went, then tick the KDP AI-generated declaration honestly. That includes cover art. KDP counts cover and interior images and artwork as AI-generated images, so a cover made by an AI image tool needs declaring even if every word inside is yours.

And check everything: every fact, every name, every quotation an AI hands you. The Department for Education warns that generative AI can produce inaccurate or false information presented as fact, and it does so in exactly the same tone it uses when it’s right. You’re the one whose name is on the cover, so you’re the one who checks.

Rules and risks

First, KDP. You need to tell it about AI-generated content (text, images or translations) when you publish a new book, or when you edit and republish an existing one. AI-assisted content needs no disclosure. The test is the one above: did the tool create the content, or did you create it and use the tool to improve it?

You’re also responsible for checking that all AI-generated and AI-assisted content follows KDP’s content guidelines, intellectual property rights included. “The AI wrote it” isn’t a defence. KDP also won’t sell content meant to mislead customers, or content that doesn’t accurately represent the book.

Now the UK copyright side, which is murky. The Copyright, Designs and Patents Act 1988 has a provision for computer-generated works. Under section 9(3), for a literary, dramatic, musical or artistic work that is computer-generated, the author is taken to be the person by whom the arrangements necessary for the creation of the work are undertaken. Section 178 defines “computer-generated” as generated by computer in circumstances where there is no human author of the work.

There’s a catch on duration. Under section 12(7), copyright in a computer-generated work expires 50 years from the end of the calendar year in which it was made. That’s shorter than the usual term for human-authored works, which runs from the author’s death. So the more of a book is genuinely yours, the more clearly it’s a human-authored work under the ordinary rules.

How copyright applies to any specific AI-assisted book is unsettled, and it might change. The UK government (the IPO, DSIT and DCMS) ran a consultation called Copyright and Artificial Intelligence from 17 December 2024 to 25 February 2025. It covered, among other things, copyright protection for computer-generated works, and the government says it is analysing the feedback. For AI images more broadly, see is it illegal to use AI art?
