Can you copyright an AI-assisted novel in 2026?

The U.S. position, with its limits

This guide concerns United States copyright and registration practice, checked on October 26, 2026. It provides general information for writers, not an assessment of a particular manuscript. Other countries may apply different rules, and the relevant facts can include publication history, contracts and contributions by other people.

The Copyright Office’s January 2025 report says AI assistance does not automatically defeat protection. Human-authored expression that remains perceptible in an output, creative modifications and sufficiently creative selection or arrangement can matter; purely generated expression is not protected as human authorship. Protection is limited to qualifying human contributions. [1]

In Thaler v. Perlmutter, the D.C. Circuit affirmed refusal of registration for a work whose application named a machine as sole author. The opinion did not decide every form of human–AI collaboration. [2] The Supreme Court denied the petition for review on March 2, 2026. A denial of review is not a new merits ruling establishing a test for mixed manuscripts. [3]

Identify expression before trying to measure effort

U.S. copyright protects original works of authorship fixed in a tangible medium. Protection for qualifying work arises upon fixation; registration is a separate process. [4] For a novelist, the inquiry begins with the manuscript and the expression claimed in it. A folder of instructions can help explain how the manuscript developed, but its size cannot substitute for identifying that expression.

Section 102 excludes ideas, systems and concepts from copyright protection. Section 103 limits protection in a compilation or derivative work to the author’s contribution, without creating ownership of preexisting material. [5] Circular 33 also explains why titles and short phrases ordinarily fall outside copyright. [6] A distinctive premise, an attractive title and a well-organized planning board can be valuable creative work without each becoming an exclusive copyright asset.

Consider an invented example. You write a scene in which a daughter discovers a forged letter. A tool proposes changes, and you retain your original dialogue while rewriting the discovery. Preserve the original scene and the revision so that the human-written language is identifiable. In a different workflow, a tool supplies the first scene and you rewrite it. Keep both versions and describe the changes precisely. These records help present the facts; neither example supplies a legal verdict about the finished passage.

A registration should describe the work actually submitted

The Copyright Office’s 2023 guidance instructs applicants to identify their human contribution and disclose more than a de minimis amount of AI-generated material, excluding that material from the claim. It advises against naming an AI system as author. Applicants with pending or completed registrations that omitted relevant AI material should follow the Office’s correction instructions. [7]

Prepare a working inventory before filling in the application. Identify the version you intend to deposit, the passages you composed, material generated by tools, third-party excerpts and the nature of your revisions or arrangement. If the history is incomplete, say where it is incomplete. An editor’s impression that the prose “sounds human” cannot repair missing information about its origin.

Do not copy a confident authorship description from another writer’s application. “Text,” “editing” and “selection and arrangement” should refer to contributions you actually made and can explain. Likewise, a publisher’s checkbox asking whether AI was used may be broader or narrower than the registration question. If your publisher handles registration, give it an accurate account before it files.

Use the Copyright Office’s literary works registration resource [8] to reach current applications and instructions. Where generated and human expression are difficult to distinguish, seek advice about the specific manuscript. The appropriate answer can depend on facts that a general guide cannot see.

Registration timing can affect enforcement

Registration is generally required before an infringement suit concerning a U.S. work, subject to statutory exceptions. Section 412 also limits eligibility for statutory damages and attorney’s fees when infringement begins before registration; its published-work provision includes a three-month period after first publication. These rules contain exceptions and do not guarantee a recovery. [9]

Put registration into the publication schedule rather than leaving it until a dispute appears. Record when and how the work was first distributed, including any earlier editions. If you have serialized chapters, circulated advance copies or revised a previously published book, check how those facts affect the application. Avoid guessing a publication date because it makes the form easier to finish.

A practical preparation folder can contain the deposit version, the completed application, payment and correspondence records, an account of excluded material and the contribution inventory used to prepare the claim. Keep that folder with your publication records. It should be possible to tell which edition a registration concerns without comparing filenames from memory.

Permission from an AI provider has a narrower job

OpenAI’s individual Terms of Use allocate rights in input and output between the user and OpenAI to the extent permitted by law, and warn that outputs may be similar to other users’ outputs. That contract does not promise that every output qualifies for copyright or is exclusive to you. [10] Other providers and regional agreements require their own review.

Keep a copy of the applicable service terms and the date you used the service when the output matters to a publication. Record the account type as well: a consumer subscription, an enterprise workspace and an intermediary writing application may involve different agreements. If a collaborator supplied material, establish what rights and permissions that person can grant before assuming their access to a tool resolves yours.

What an authorship evidence package can establish

A useful evidence package connects a specific version to its sources, recorded assistance and revisions. It can show that a file existed in a recorded form, that an instruction was submitted or that a decision was saved. An author’s statement may explain an action that the software did not observe. Those different kinds of evidence should remain labeled.

A timestamp does not establish who composed a sentence, and a file hash identifies file contents without proving originality. Missing AI records do not establish that AI was absent. A private record may still be useful even when it is incomplete, provided the gaps are visible. The contribution-record template shows a manageable way to retain that distinction.

PennedCanon’s public description of its Authorship Evidence Package makes the same limitation explicit: it supports an explanation of a selected saved version and does not determine copyrightability or guarantee registration. Treat documentation as preparation for a claim that must stand on its facts. For the separate question of how to describe yourself to readers, see authorship and creative contribution.
