Entry 01 · The question

Can AI output be copyrighted?

Under U.S. law, copyright protects human authorship — and only that. Work generated purely by a machine gets no protection. But most real projects aren't purely machine-made: a person makes choices, edits, arranges.

So the honest answer isn't yes or no. It's “where on the spectrum of human contribution does this sit?” — judged work by work, fact by fact.

Hold this line

No human authorship → no copyright. The real work is identifying what a person actually authored inside an AI-assisted project.

Educational, not legal advice. U.S. copyright focus, as of 13 November 2026. Specific facts control; verify before relying on it.

The brief

What you'll be able to do

1
Explain why purely AI-generated work gets no federal copyright.
2
Place a project on the spectrum of human contribution.
3
Identify where copyright can attach — selection/arrangement and substantial modification.
4
Separate copyright from contract (Terms of Service).
5
Keep records that prove your human contribution.

Entry 02 · The baseline

Why pure AI output isn't copyrightable

Thaler v. Perlmutter settled the baseline: a work generated purely by AI, with no human author, cannot get federal copyright.

The prompt analogy (Copyright Office, Part 2 Report). A prompt works like instructions given to an artist. It guides the concept — but the system decides the actual expression. The prompter lacks direct creative control over the final output, so the prompt alone isn't authorship.

That's the floor, not the whole story. It does not make every AI-assisted work uncopyrightable — it just means the machine's own output, untouched, carries no protection. Everything else depends on what a human adds.

Entry 03 · Where it attaches

Two places copyright can attach

① Selection & arrangement

Curating and sequencing material — e.g. ordering panels into a coherent story — can earn compilation copyright, even if each piece isn't protected on its own.

② Substantial modification

Painting over, compositing or retouching raw output adds protectable human layers — your creative expression sits on top of the machine's.

Same test, two routes. Both ask the same thing: did a human make real creative choices? Protection covers those choices — not the underlying raw generation.

Entry 04 · Copyright vs contract

Owning by contract isn't owning by copyright

A platform's Terms of Service may grant you commercial permissions or even contractual “ownership” of outputs. Useful — but it's a different thing from copyright.

Contract (ToS) binds only the users who agreed to it. It can't stop the public from copying work that has no copyright.

Copyright is a federal right good against the world — but it only exists where there's human authorship.

And “no copyright” ≠ “free for all.” Output with no copyright can still breach a contract, infringe its source data, or violate a trademark. Rights and liabilities always turn on the specific facts.

Entry 05 · Practical habit

Document where the tool stopped

Because protection turns on your contribution, your strongest asset is evidence of it. Keep the receipts:

1
Layered project files — keep the editable stack showing your compositing, painting and retouching.
2
Version history — raw generation → your successive edits, so the human steps are visible.
3
Selection notes — why you chose and sequenced what you did (supports compilation claims).

The goal: be able to show clearly where the tool stopped and your creative work began.

The record

0/3

Knowledge-check score

No human authorship, no copyright. Thaler sets the floor; a prompt alone isn't authorship.

It's a spectrum. Protection grows with real human creative contribution.

Two routes in. Original selection/arrangement (compilation) and substantial modification (layers).

Copyright ≠ contract. ToS binds users; copyright binds the world — and “no copyright” isn't “free.”

Document everything. Layered files and version history prove your contribution.

Glossary

Compilation copyright — protection for an original selection and arrangement of material, even when the pieces aren't protected. Transformative use — a use adding new purpose/character. Digital replica — an AI likeness or voice of a real performer. Provenance — metadata recording how media was made.
