Public verifier · Art. 50

Is this audio marked as AI-generated?

Upload a file. The verifier reads the C2PA manifest, listens for the imperceptible watermark and looks up the disclosure record. Free, no account.

WAV, MP3, FLAC or OGG, up to 50 MB. The file is analysed and discarded; nothing is stored unless a disclosure record already exists.

What is checked

  1. 01

    C2PA manifest

    Signed metadata travelling with the file: who generated it, when, and with which tool. The signature chain is validated against the trust list.

  2. 02

    Imperceptible watermark

    A signal embedded in the audio itself that survives re-encoding and trimming. Detection returns a confidence score.

  3. 03

    Disclosure record

    The public record the provider created for this output: system, organisation, consent of the voice owner, date. Linked to a page like this one.

The Code of Practice on Transparency of AI-generated Content asks providers for free detection of their marks. This is ours.
