Who owns AI-generated content? You, the tool, or nobody

Who owns what an AI tool makes for you? There are two answers, and they come from different places. One is the contract you accepted when you signed up for the tool. The other is copyright law, which decides whether there is anything to own in the first place.

This page puts the two side by side. It is part of our section on copyright and AI. We quote each tool's own terms page, with the date we read it, because terms change. For the copyright test itself, see our guide to the human authorship test for AI content.

01Ownership by contract: what the terms say

Here is what three widely used tools say about output, quoted from their own pages as we read them on October 30, 2026:

Sources: Anthropic Consumer Terms of Service, Midjourney Terms of Service and OpenAI Terms of Use.

Notice the pattern. Each company hands over its own rights, "to the fullest extent possible" or "if any." None promises that a copyright exists. That is because a contract cannot create a copyright the law does not recognize.

02Ownership by copyright: what the law adds

Copyright belongs initially to the author of a work, under Section 201(a) of the Copyright Act. For AI output, the question is whether there is an author at all. The Copyright Office's March 16, 2023 registration guidance says that when an AI system "determines the expressive elements of its output, the generated material is not the product of human authorship" and "is not protected by copyright."

That leaves three common situations:

• You only prompted. The output itself likely has no copyright owner. You may still have contract rights from the tool, and anyone who copies it may not be infringing anything.
• You changed, selected or arranged it. You own copyright in your creative contribution. The AI-made parts stay unprotected.
• You used AI as a helper on your own work. If you wrote the text and used AI to fix spelling or suggest edits, the work is yours.

The Copyright Office's position, and the court rulings behind it, are summarized in the Copyright Office's AI guidance explained.

03Commercial use and selling

Can you sell AI output? Under all three sets of terms quoted above, generally yes, subject to their conditions. OpenAI's terms say you can use content "for any purpose, including commercial purposes such as sale or publication, if you comply with these Terms."

What you may not have is exclusivity. If your book cover or T-shirt design is purely AI-generated, a competitor who copies it may face no copyright claim from you, because there may be no copyright to enforce. Two practical points follow:

• Add your own layer. Your own text, illustration, layout and edits are what you can actually protect.
• Think trademark for brand assets. Logos and product names are usually protected by trademark law, a separate system with its own rules. See copyright vs trademark, including AI-made logos.

04When the output resembles someone else's work

Owning the output under a contract does not protect you if the output copies someone else's protected work. Each set of terms quoted above puts that risk on the user. Anthropic's consumer terms bar using the service "to infringe, misappropriate, or violate intellectual property," and Midjourney's terms say you may not use the service "to try to violate the intellectual property rights of others."

In practice, check output that looks like a known character, artwork, photo or song before you publish it. If a famous character or a living artist's recognizable work shows up, do not assume the tool's terms cover you. Questions about what went into the model, and whether training itself was lawful, are a separate issue covered in whether AI companies can train on your work.

05Work for hire, clients and employers

If you make something with AI for a client or an employer, two layers apply on top of the tool's terms.

• Employees. Under Section 201(b) of the Copyright Act, an employer owns works made for hire by employees within the scope of their job. That covers your human contribution. It cannot turn purely AI-generated material into a protected work: in Thaler v. Perlmutter on March 18, 2025, the D.C. Circuit held the work-for-hire rule still requires a human creator.
• Freelancers. Your contract decides what you hand over. Many client agreements promise that the work is original and that you own and can assign it. If parts are AI-generated, you may not be able to promise that. Tell the client, and agree in writing how AI may be used.
• Company tool accounts. If you use a work email, some tools link your account to your employer's plan, and the employer's agreement with the vendor may apply. Anthropic's consumer terms, for example, say an organization's administrator may be able to access materials in such accounts.

When a contract depends on these answers, talk to a lawyer licensed where you live.
