Can you copyright a book written with AI?
Parts of it, yes. The words a model generated from your prompt are not protected in the United States; your selection, arrangement, additions and edits are. Here is where the line sits after the 2025 Copyright Office report and the courts.
The rule
US copyright requires a human author. In January 2025 the Copyright Office published Part 2 of its Copyright and Artificial Intelligence report, on copyrightability, and its conclusion was blunt: material generated purely from prompts is not copyrightable, because "prompts alone do not provide sufficient human control" over the output. The Office noted that the same prompt produces different results each time, which is the opposite of an author dictating expression.
The courts agree. On 18 March 2025 the DC Circuit affirmed the refusal to register an image that Stephen Thaler said his "Creativity Machine" created autonomously, holding that a work must be authored in the first instance by a human being. On 2 March 2026 the Supreme Court declined to hear the appeal, so that ruling stands.
What is protected in an AI-assisted book
The report is careful to distinguish AI-generated from AI-assisted work, and it lists what human contribution can earn protection. Law firms summarising the report converge on the same points:
| Element | Protected? |
|---|---|
| Your outline, chapter order and the way the book is arranged | Usually yes, as a compilation, if the choices are creative |
| Sentences a model drafted from your brief, untouched | No |
| Those sentences after you rewrote them substantially | The rewritten expression, yes; the surviving machine text, no |
| Your interview answers, anecdotes and quoted experience woven into the text | Yes |
| A cover image generated by a model | No, though the typography and layout you added can be |
| Your title | Titles are never copyrightable, AI or not |
How to register
The Office's 2023 registration guidance, restated in the 2025 report, asks you to disclose AI-generated material that is "more than de minimis" and to claim only the human-authored parts. In practice you file for the text as a whole, describe the AI-generated portion in the "Limitation of claim" section, and the registration covers what you wrote and arranged. Skadden's note on the appeal has a useful summary of the practical position.
Does this mean anyone can copy my AI book?
They can copy the unprotected machine text without infringing copyright, in theory. In practice a book built from your interview, your examples, your structure and your edits is mostly protected expression, and a copier would have to strip all of that out. Outside the US the picture varies: the UK has a computer-generated works provision, the EU requires an author's "own intellectual creation", and India's Copyright Office has been inconsistent. Take local advice for anything valuable.
What to put on the copyright page
© 2026 Your Name. All rights reserved. Drafted with the assistance of AI writing tools from the author's interview, outline and notes, and edited by the author.
This is honest, it matches what Amazon asks you to declare, and it does not overstate your claim. Neubook Write puts a line like it on every export by default; you can change the wording before you download.
Your words are the protected part. Neubook Write starts from a two-question interview and your own writing sample, so the book carries your examples and voice rather than generic filler.
