Microsoft Copilot Detector
Detect content generated by Microsoft Copilot. Our AI detection engine identifies Copilot-written text across Office documents, emails, and general content with sentence-level precision.
Microsoft Copilot is deeply integrated into the Office 365 ecosystem, helping millions of users draft emails, reports, presentations, and documents daily. Plagly.ai's Copilot Detector identifies text generated by this AI assistant. Because Copilot is built on OpenAI's models with Microsoft's proprietary fine-tuning and system prompts, its outputs carry a distinctive combination of GPT-family patterns and Microsoft-specific formatting tendencies. Our detection engine is trained to recognize these hybrid signatures, including Copilot's preference for professional tone, structured formatting, and action-oriented language. Whether Copilot was used to draft a business proposal or write an email, Plagly provides clear, sentence-level detection results.

Frequently Asked Questions
Can Plagly detect Microsoft Copilot in Word documents?
Yes. You can upload DOCX files directly to Plagly, and our engine will analyze the text for Copilot-generated patterns. This works whether Copilot drafted entire paragraphs or just suggested sentence completions.
How is Copilot detection different from ChatGPT detection?
Copilot uses OpenAI models but with Microsoft's fine-tuning, system prompts, and formatting conventions. This creates a subtly different output style that our engine distinguishes from raw ChatGPT. Both are detected with high accuracy.
Can Copilot detection work on emails?
Yes. Paste the email body into Plagly's text input for instant analysis. Copilot-drafted emails typically show professional, action-oriented language patterns that our engine recognizes effectively.
Is Copilot content harder to detect than other AI models?
Copilot content can be challenging because it is often blended with user-edited text within Office applications. Plagly's sentence-level analysis handles this mixed-authorship scenario by scoring each sentence individually.
Does Copilot detection cover Microsoft 365 Copilot for Business?
Yes. Our detection engine covers text generated by all Copilot variants including the Business tier, which uses the same underlying model architecture with enterprise-specific system prompts.
