Microsoft Is Merging Its Two Copilot Apps Into One, Explained
For about two years, Microsoft has made you pick between two apps with almost the same name: "Microsoft Copilot," the free consumer chatbot for personal chat and image generation, and "Microsoft 365 Copilot," the work-focused app bolted onto Word, Excel, Outlook, and the rest of your office subscription. That confusion ends this month. Microsoft began folding both into a single unified app on mobile and web back in mid-August 2026, and this week -- mid-September -- the same merge is landing on Windows and Mac. Here's exactly what's changing, what's disappearing, and whether your work and personal stuff are about to get mixed up in the same app.
⚡ Quick facts
- What's merging: The consumer Copilot app and the Microsoft 365 Copilot (work) app become one app, called Microsoft Copilot, with one new icon
- Timeline: Mobile/web rollout began mid-August 2026 worldwide; Windows and Mac desktop apps follow in mid-September 2026
- Retiring Aug 18, 2026: Podcasts, Deep Research (consumer report generation), and Group Chat -- none of it carries forward
- Data: Personal and work/school accounts stay isolated inside the same app; still free for basic chat and image creation
Why there were two Copilot apps in the first place
Microsoft's Copilot branding sprawled in two directions at once. The consumer-facing "Copilot" app -- free, chat-and-image-focused, roughly a ChatGPT competitor -- shipped for anyone with a Microsoft account. Separately, the old Microsoft 365 (Office) app was rebranded the "Microsoft 365 Copilot" app starting in January 2025, bolting AI features onto Word, Excel, PowerPoint, Outlook, and cloud file access for people with a work or school subscription. The result: two apps, similar names, similar icons, and a genuinely confusing choice for anyone who just wanted "the Microsoft AI app" without knowing which one had the features they needed.
What's actually changing
The two apps are becoming one. According to Microsoft and multiple outlets covering the rollout, the unified app "combines the best of Copilot chat and image creation, with the power of Microsoft 365 for your work" -- meaning Word, Excel, Outlook, PDFs, and cloud files now live inside the same shell as personal chat, and you can sign in with a personal account, a work/school account, or switch between both. It keeps the "Microsoft Copilot" name, but ships a new shared icon that replaces the two separate ones people had learned to tell apart. The rollout started with mobile and web worldwide in mid-August 2026, Windows Insiders got early access the week of August 10, and IT admins have been able to opt in test Windows and Mac devices since August 18 -- with the full Windows and Mac rollout landing in mid-September 2026, i.e. right now.
Microsoft has described this as the first structural step toward a broader "super app" it's planning to launch later in 2026 -- one place for AI chat, productivity, and agents instead of a scattered set of Microsoft apps competing for the same taskbar space.
Will your work and personal data mix together?
Microsoft's position, repeated consistently across its own support documentation and independent coverage, is no. Data separation is preserved by design: a work or school account authenticated through Microsoft's Entra identity system stays isolated from a personal Microsoft account, even though both can now live in the same app. Enterprise security controls, compliance settings, commercial data boundaries, and tenant administration policies continue to apply unchanged on the work side. In practice that means IT admins still control what a work account can do and see, while your personal chats, images, and files stay in their own lane -- the app just stops making you open a second program to get to them.
What's being retired
The merge isn't purely additive. Starting August 18, 2026, three consumer-app features are being shut down and won't carry forward into the unified app: Podcasts (both creating and accessing them), Deep Research -- the consumer app's automated report-generation tool -- and Group Chat, including existing threads, messages, and any images generated inside them. Anyone who relied on those specifically should be aware they're going away, not migrating. Pricing otherwise stays the same: the core experience -- basic chat, image creation, file uploads -- remains free, and the deeper Microsoft 365 productivity features still require a Microsoft 365 subscription, same as before the merge.
Why this matters beyond a rebrand
On its own, "two apps become one app" is a housekeeping story. It matters here because it's part of the same industry pattern this site keeps tracking -- major AI companies consolidating what used to be several separate assistants into a single default experience, the same shift behind Google retiring Google Assistant in favor of Gemini on Android. Fewer apps, one identity, one place AI shows up by default -- that's the direction every major platform is converging on right now, not just Microsoft's.
Frequently asked questions
What is Microsoft actually merging?

Will my personal and work data get mixed together?
No. Microsoft says data separation is preserved by design -- a work or school account signed in through Microsoft's Entra identity system stays isolated from a personal Microsoft account, even inside the same app, and enterprise security and compliance controls continue to apply unchanged.
What features are being removed?
Starting August 18, 2026, the consumer app's Podcasts feature (creation and access), Deep Research report generation, and Group Chat (including existing threads, messages, and generated images) are being retired and won't carry forward into the unified app.
