The short answer

The EU AI Act does not require every AI company to put one particular “signature” in every video. Article 50 and the Commission's guidelines require providers of AI systems that generate or manipulate synthetic audio, image, video or text to make covered outputs machine readable and detectable as AI-generated or manipulated, as far as technically feasible. The rule is about the result, not a mandate to use C2PA or one watermark brand.

The transparency rules began applying on 2 August 2026. Under the amended timeline, certain systems already placed on the market before that date have until 2 December 2026 to meet the Article 50(2) marking and detection obligation. The EU AI Act Service Desk timeline sets out both dates.

Machine-readable marking and visible disclosure are different duties

The provider obligation concerns the AI system and machine-readable marks on covered outputs. The deployer obligation can require a clear disclosure to people for deepfakes or certain AI-generated public-interest text. A hidden mark alone does not satisfy a required visible or audible deepfake disclosure. The Commission's Article 50 FAQ explains the distinction and its exceptions.

The rules are not a blanket label requirement for every AI-assisted edit. The Commission describes exceptions, including standard editing assistance that does not substantially alter the input or its meaning. Whether a particular creator or workflow is covered depends on the role, content and use. For current scope and examples, use the Commission guidelines, not a general claim that “all AI content must have C2PA.”

What this means for a metadata cleaner

Free AI Wiper can inspect and remove selected supported portable file metadata. It cannot determine whether someone has a legal disclosure duty or make a publication compliant by changing a file. If provenance or a disclosure is required for your workflow, preserve it and follow the applicable rules. A platform may also keep its own label or record after a file is changed. See the different signal types and why labels can remain.
