Copilot
Summarize and explain PDFs with Copilot in Microsoft Edge
[Web]
Microsoft Edge expands its built-in PDF reader with new Copilot actions that help you quickly summarize or explain PDF content directly in the browser.
Roadmap ID:
498641
Details:
What changed:
The existing Ask Copilot experience in the Microsoft Edge PDF reader now includes two additional actions-Summarize and Explain-that let you generate a concise overview or simplify complex sections of a PDF or selected content. These actions follow the same enterprise controls and policies already applied to Copilot in Edge.
Why:
Reviewing long or complex PDFs often requires extra time and context switching. This update makes it easier to understand key points or technical language without leaving the PDF reader or copying content into another tool.
Try this:
Open a PDF in Microsoft Edge and select Summarize to get a quick overview of the document.
Select a paragraph or section and choose Explain to simplify complex language or concepts.
Why this matters:
Business impact:
Helps teams review documents faster and stay within existing enterprise controls while using Copilot in Edge.
Personal impact:
Makes it easier to understand lengthy or technical PDFs without interrupting your workflow.
