Updated October 20, 2026: We have decided not to move forward with this change at this time. We apologize for any inconvenience.
What and why:
Microsoft 365 Copilot makes PDF reviews faster and easier on mobile. Select text in any PDF in OneDrive iOS and tap Ask Copilot to explain, summarize, translate, or ask a custom question about the selection — the same in-context Copilot experience already generally available on desktop, now on OneDrive iOS.
When this will happen:
General Availability (Worldwide, GCC, GCC High, DoD): We have decided not to move forward with this change at this time.
Impact on your organization:
When this rolls out, users viewing a PDF in OneDrive iOS can select text and see Ask Copilot in the context menu. Tapping it opens Copilot with the selected text as context, so they can:
- Explain dense or technical passages in plain language
- Summarize long sections
- Translate into another language
- Custom prompt: add their own prompt for tailored results — no need to switch apps
The feature is on by default where Copilot is enabled.
Steps to use Ask Copilot in OneDrive iOS:
- Open the OneDrive app on iOS and sign in with your work account.
- Open the PDF you want to review.
- Select any text in the PDF. The context menu will display Ask Copilot.
- Tap Ask Copilot for a plain-language explanation or type your own prompt for tailored results.
Licensing requirements
A Microsoft 365 Copilot license is required to use this feature.
Action required / Recommendations:
No admin action is required. You may want to:
- Review your Copilot license assignments for mobile users.
- Update user-facing training/help content to mention Ask Copilot in PDFs on OneDrive iOS.
- Notify your help desk of the new entry point.
Note: Some users may see this feature before others in your organization.
Compliance considerations:
This feature follows your existing Copilot data-handling and enterprise data protection commitments. Review as appropriate for your organization.
