Feature overview

Microsoft Edge will expand its existing “Ask Copilot” integration in the built-in PDF reader by introducing two new actions — “Summarize” and “Explain.” These options will allow users to generate a concise overview or simplify complex content within a PDF or selected portion. The new actions build on the existing “Ask Copilot” integration and follow the same enterprise controls and policies.
