Microsoft Copilot AI detector

Microsoft 365 Copilot is integrated into Word, PowerPoint, Excel, and Outlook, generating millions of professional documents and emails every day. This detector verifies whether professional documents were authored by Copilot.

It examines language predictability, standard corporate phrasing templates, and PDF metadata to reveal whether an AI assistant composed the submission.
