One Copilot to Rule Them All: Microsoft Combines Its Apps
Confused by Microsoft's collection of similarly named Copilot apps? Microsoft is consolidating its Copilot experiences into one updated app that can handle personal, work, and school accounts and, for eligible users, create Word documents, Excel workbooks, and PowerPoint presentations.

If you've ever looked at Microsoft's assortment of Copilot apps and wondered which one you were supposed to open, Microsoft has apparently heard you.
The company is consolidating existing Microsoft Copilot and Microsoft 365 Copilot app installations into a single Microsoft Copilot application experience.
The updated app can support personal, work, and school accounts while connecting Copilot with Microsoft 365 apps, files, and content.
One clarification is important. Microsoft isn't renaming the entire Microsoft 365 service.
The Microsoft 365 (Office) app and the standalone Copilot app are now being brought together under the unified name Microsoft Copilot.
There's another benefit hiding behind that name change.
Eligible users can use Word, Excel, and PowerPoint Agents inside Microsoft Copilot to create actual documents, workbooks, and presentations simply by describing what they need.
For most existing users, the transition should not require much work.
Most updates happen automatically, and web users are automatically redirected to the updated Copilot experience.
Here’s a Cool Tip: Use the new unified Copilot as your starting point for chat, files, Word, Excel, and PowerPoint.
The biggest benefit of Microsoft's Copilot consolidation is simplicity.
Microsoft describes the change as application unification, updating existing Microsoft Copilot and Microsoft 365 Copilot app installations to a single Copilot application experience.
If you've been using Copilot with a personal account, your chat history and most content move with you.
If you've used both of Microsoft's Copilot app experiences with a personal account, your chats and created content will be brought together in the updated app.
The updated app can also handle personal, work, and school identities.
You can switch between them with the account switcher, but that doesn't mean personal and business information gets mixed together.
Personal and organizational experiences remain separate by design.
Word, Excel, and PowerPoint Join the Party
This is where the change becomes much more interesting than a new name and icon.
Microsoft Copilot includes Word, Excel, and PowerPoint Agents for eligible Microsoft 365 users.
Instead of opening a blank file and starting from scratch, you can describe the file you need and let the appropriate agent build a first draft.
You might ask Word to draft a project proposal, Excel to create a budget tracker with charts, or PowerPoint to build a marketing presentation.
Copilot generates a preview, saves the finished file to OneDrive, and lets you open it in the corresponding Office application for further editing.
You can also give the agent broader feedback, such as asking it to shorten a document or add a slide.
There is an important limitation.
These Word, Excel, and PowerPoint Agents are available to Microsoft 365 users with a Microsoft 365 Copilot license.
Microsoft also offers editing with Copilot for Microsoft 365 Personal, Family, Premium, and Pro plans.
This capability, previously marketed as Agent Mode, is now integrated into the regular Copilot experience.
The result is a Copilot experience that's beginning to look less like an AI chatbot sitting beside your productivity tools and more like a front door to them.
There are tradeoffs in the transition.
Group Chat and Podcasts ended after August 18, 2026, and Microsoft began retiring Deep Research from the consumer Copilot app on August 18, 2026.
What You’ll Gain
- Reduce app confusion with one primary Copilot application experience.
- Switch between accounts while keeping personal and organizational information separate.

Try It With Word
- Choose Word and describe your document.
- For example: "Create a two-page proposal for a neighborhood landscaping project, including goals, estimated expenses, timeline, and next steps."
- Review the result and revise anything that needs attention before sharing it.
Try It With Excel
- Choose Excel and describe the workbook you need.
- For example: "Create a household budget tracker with monthly income and expenses, summary charts, and year-to-date analysis."
- Review the result and revise anything that needs attention before sharing it.
Try It With PowerPoint
- Choose PowerPoint and describe your presentation.
- For example: "Create a 10-slide presentation about our 2027 marketing strategy with an introduction, analysis, recommendations, and conclusion."
- Add details about the audience, purpose, organization, and desired length to help Copilot understand what you want. Microsoft documents creating a 10-slide marketing strategy deck as an example.
iPhone/iPad and Android
- Open the Microsoft Copilot mobile app (iOS, Android).
- From Chat, ask Copilot to create a Word, Excel, or PowerPoint file.
- Describe the file you want.
- Copilot creates a download link for the file.

The unified app and its capabilities vary according to account type, subscription, platform, organizational controls, and region.

There are additional requirements for some Office features.
