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.
