Disclaimer:
This tool uses a PDF’s metadata fingerprint to provide guidance on whether an invoice may have been generated by AI. Users should rely on their own further investigations to determine whether the document uploaded is authentic and accurate. Users should not rely on this tool alone to determine whether to process an invoice under their organisation’s normal procedures.
