How do you prove you wrote AI-assisted song lyrics?

Yes — the parts a person wrote can be protected, while the parts a machine generated cannot. Copyright in the United States covers original human expression, so a lyric written with an AI tool is treated as a mixture: your words are claimable, the tool's words are not.

That means the practical question is never whether AI was involved. It is whether you can point to the expression you contributed and describe it clearly.

It requires disclosure and a disclaimer: an application must identify the human authorship being claimed and disclaim AI-generated material that is more than de minimis. This comes from the Office's statement of policy of March 16, 2023 (37 CFR Part 202, 88 FR 16190), developed further in Parts 2 and 3 of its report on copyright and artificial intelligence.

The clearest illustration is the Théâtre D'opéra Spatial Review Board decision of September 5, 2023. Registration was refused because the applicant declined to disclaim the AI-generated content — not because a generative tool had been used. Using AI is not the problem. Failing to disclose it is.

The risk that actually bites people is therefore an incomplete application. A registration secured without the required disclosure is weaker than no registration at all, because it can be challenged on that basis later.

No — the Copyright Office has published no percentage, and any specific figure you see quoted is not from the Office. Commentary often suggests thresholds such as "at least eighty per cent human," and that framing is inaccurate.

What is assessed is whether original human expression appears in the work and can be identified. A short, wholly human chorus can carry a claim; a long lyric that a person only lightly touched may not. Counting words is not the test, so build your record around what you contributed rather than around hitting a ratio.

Re:Writ does calculate a percentage score and an H-5 through A-1 tier, but those figures reflect how much of the writing the human did according to Re:Writ's own methodology. They are not a legal standard, carry no official weight with the US Copyright Office or any court, and no score guarantees or predicts any registration outcome.

Copyright is generally automatic in the European Union rather than obtained through a US-style registration filing, so there is no parallel application mechanism for disclaiming AI-generated parts.

The EU AI Act contains transparency and labeling duties in certain settings, but those duties are different from copyright registration guidance. This page does not attempt to provide broader EU legal guidance.

Keep dated drafts, the untouched tool output, line-level provenance, tool-use notes, co-writer roles, revision and deletion history, creative-direction material, and supporting uploads in an exportable record.

1. 1Save a dated snapshot of each draft

   Keep a separate, dated copy of the lyric at each stage rather than overwriting one file, so the order in which the words appeared can be shown later.

2. 2Keep the pre-edit original

   Preserve the text exactly as a tool produced it, before you edited it, so your own edits can be compared against the material you did not write.

3. 3Mark which lines are yours and which came from a tool

   Record authorship at the line level — written by you, tool output you rewrote, or tool output you accepted as-is — because a lyric is normally a mixture rather than all one or the other.

4. 4Record the tool names and how each was used

   Note every AI tool involved and what it did, such as drafting a bridge, suggesting rhymes, or generating a full first pass.

5. 5Record co-writer names and their roles

   List each human contributor and what they contributed, since joint authorship affects who is named on a registration.

6. 6Keep revision, deletion and creative-direction evidence

   Preserve the order of revisions, a record of deleted lines, creative-direction notes, and supporting uploads such as handwritten drafts, images and voice memos.

7. 7Keep the record in exportable form

   Store the drafts, line-level tags, tool notes, dates and supporting evidence together in records you can export, so the history remains available if you change tools or devices.

The reason to keep the pre-edit original is that it is the only way to show the difference between what a tool produced and what you did to it. Once you have edited over the top of it, that comparison is gone for good.

Re:Writ keeps human and AI source material in distinct writing lanes while allowing sections and lines to be arranged freely into the finished lyric.

Writers can bring in both their own lyrics and AI-generated lyrics. AI Draft holds AI-origin or reference material, Note Draft holds human-written material, and Fair Copy is the assembled song; sections can move into Fair Copy and lines can be reordered as the song develops.

Each Fair Copy line can be tagged Human, Mixed or AI. Re:Writ also keeps dated draft snapshots, line retagging events and a deletion ledger, so the record shows both the current lyric and material removed during revision.

Re:Writ preserves the original pre-edit AI text alongside the writer's revised line, and includes both versions in the exported evidence record.

This creates a direct artifact of transformation: the record can show what the tool produced before editing and what the writer made from it, rather than asking the writer to reconstruct that difference later from memory.

Re:Writ records creative direction through separate tools for non-AI writing, AI assistance, visual references, session notes and supporting files.

A completed Re:Writ song produces a certificate that is the workspace's most complete evidence record of content, timing, integrity and provenance.

The certificate includes a SHA-256 content hash and completion timestamp. Writer and Studio plans can cryptographically sign the record. When Registry registration completes, the certificate receives a Registry ID in the Veridem Authorship Registry, and its QR and external verification link let a third party check that Registry record independently. PDF and JSON exports preserve readable and structured copies of the evidence.

The hash identifies the certified content; the timestamp records when it was completed; the signature supports an integrity check; and the Registry entry provides a separate lookup record. These are evidence for an examiner, court, attorney or collaborator to evaluate, not a grant of legal rights.

The certificate also displays Re:Writ's percentage score and H-5 through A-1 tier. Those figures describe human contribution under Re:Writ's own methodology; they are not a legal standard, have no official weight with the US Copyright Office or any court, and do not guarantee or predict registration.

A certified Re:Writ record has no user deletion path and survives account closure because an evidence record that other people may rely on should not be erasable by the person it benefits.

Closing an account removes unfinished work and personal account information, while finalized, registered certificate content is preserved without its former account link. This is a Re:Writ preservation rule; it does not mean the storage technology itself is physically immutable.

It is a separate obligation: platform AI disclosure is metadata attached to a release, while a copyright disclaimer is a statement made in a registration application. They use different wording, go to different recipients, and happen at different times.

• DistroKid AI Credits asks at upload whether AI generated the lyrics, vocals, instrumental performance or composition.
• Spotify AI Credits entered beta on April 16, 2026 with DistroKid as the first delivery partner. It is carried in DDEX delivery metadata, and the tag currently appears in the credits view on mobile. Spotify has stated that the absence of a tag does not mean AI was not used.
• Apple Music Transparency Tags began phasing in during March 2026 and remain optional at the time of this review.

Two consequences follow. Answering a distributor's AI questions does nothing for a copyright application, and a copyright disclaimer does nothing for your streaming credits. And because the disclosure travels as delivery metadata, a distributor that does not populate those fields ships your release without them regardless of what you entered — so keep your own copy of what you declared.

Re:Writ produces the authorship record during the writing process, so the evidence does not have to be reconstructed after the song is finished.

It timestamps drafts, keeps revision and deletion history in order, preserves pre-edit AI originals, records Human, Mixed and AI line tags, and gathers the result into PDF and JSON evidence exports.

Can I register a lyric that an AI helped me write?

Yes, you can seek registration for the human-authored parts of the lyric, and you must disclaim the AI-generated material in the application. The machine-generated text itself is not protected.

How much of the lyric has to be human-written?

The Copyright Office publishes no percentage. It looks at whether original human expression appears in the work, so a fixed ratio is not the test.

Is a Re:Writ score a Copyright Office standard?

No. Re:Writ's percentage and H-5 through A-1 tier describe human contribution under Re:Writ's own methodology; they carry no official weight and do not predict or guarantee registration.

Does Re:Writ keep the original version of an edited AI line?

Yes. When an AI-origin line is edited in Re:Writ, its original pre-edit text is preserved alongside the rewrite and included in the exported evidence record.

Does writing in Sketchpad create an AI disclosure obligation?

No. Sketchpad does not use AI; its prompts, sentence starters, word bank, rhyme families and synonyms are non-AI writing aids.

What does a Re:Writ certificate prove?

A Re:Writ certificate is evidence of recorded content, timing, integrity and provenance. It does not confer copyright, conclusively prove ownership or guarantee a registration outcome.

Can a certified Re:Writ record be deleted?

No. Re:Writ does not provide a deletion path for a certified record, and a finalized, registered record is preserved if its creator closes their account.

Does the European Union use the same AI disclaimer process?

No. Copyright is generally automatic in the European Union rather than obtained through a US-style registration filing, so there is no parallel application mechanism for disclaiming AI-generated parts. EU AI Act transparency duties are a different obligation.

Is platform AI disclosure the same as a copyright disclaimer?

No. Music-platform metadata and a US copyright application are separate obligations with different recipients, wording and timing.
