Microsoft 365 Copilot: Updates to PowerPoint on‑canvas features with Agent mode [MC1243550]

Message ID: MC1243550

[Introduction]

As previously announced in MC1219792, PowerPoint will update the Microsoft 365 Copilot experience by enabling Agent mode for several on‑canvas authoring features, including rewrite, translate, and speaker notes. These enhancements will support more intelligent multi‑step reasoning and allow users to interact with Copilot through chat while performing actions directly on their presentations. This update aligns with our goal of delivering a more consistent, flexible, and powerful Copilot experience across Microsoft 365 apps.

[When this will happen]

General Availability (Worldwide): Rollout will begin in mid‑March 2026 starting with PowerPoint for the web, followed by PowerPoint for Windows (Win32) and PowerPoint for Mac, and is expected to complete by end of April 2026.

[How this affects your organization]

Who is affected

• Users of PowerPoint for the web, Windows, and Mac in Microsoft 365 tenants with Copilot access

What will happen

Rewrite

• Rewrite actions will be processed through Copilot Agent mode chat.
• Users will see progress and outputs directly in chat.
• Updated text will automatically appear on the slide.
• Existing rewrite entry point and options will remain unchanged.
• Partial text rewrite will not be supported.
• Rewrite will continue to not support tables, charts, or other non‑text objects.
• Rewrite will be enabled by default for tenants with Copilot access.

Translate

• Users will be able to initiate translation for a text box, a selected slide, or an entire presentation using Copilot Agent mode chat.
• Users will be able to prompt chat with: “Translate this presentation to [language].”
• The Copilot slide menu (sparkle icon) for translation will be removed starting in mid‑March for PowerPoint for the web, followed by Windows and Mac in April.
• Presentation‑level translation will continue to function as before.
• Translation will not support presentations larger than 1M text characters, with a large number of slide masters, or file sizes larger than 500MB.
• All Copilot‑supported languages will be available; however, English and Spanish will not support regional variants.
• During the transition, Copilot may edit the current file. Users should save a copy before initiating translation if needed.
• Translate will be enabled by default for tenants with Copilot access.

Speaker notes

• Users will be able to generate speaker notes for a slide or an entire presentation through Agent mode chat.
• Users will be able to prompt: “Add speaker notes to this slide.”
• Notes will be inserted directly into the Notes pane and can be refined using chat.

[What you can do to prepare]

No admin action is required.

However, you may consider the following optional steps:

• Inform users of upcoming changes to rewrite, translate, and speaker note workflows.
• Ensure that users intending on using this feature have an active Microsoft 365 Copilot license.
• Update internal training or documentation related to Copilot in PowerPoint.
• Encourage users to save a copy of large or critical presentations before initiating translation during the transition period.
• Notify users if your organization currently trains or instructs users to rely on the sparkle icon, as it will be removed.
