Microsoft has responded to OpenAI’s new ChatGPT Atlas browser within just 48 hours, launching its own ‘Copilot Mode’ for Edge. This move escalates the AI browser war, positioning Edge as a direct competitor in the AI-centric browsing space.
Key Takeaways
- Microsoft launched Copilot Mode for Edge browser days after OpenAI’s ChatGPT Atlas reveal.
- The feature transforms Edge into an “intelligent companion” capable of performing complex tasks.
- Available immediately for Windows 11 users, with Mac and mobile versions coming soon.
Microsoft’s AI Browser Counterattack
Mustafa Suleyman, CEO of Microsoft AI, announced Copilot Mode as the company’s official entry into the AI browser category. The enhanced Edge browser now functions as a “dynamic, intelligent companion” that can handle advanced, agentic tasks according to Suleyman.
Copilot Mode vs ChatGPT Atlas: Feature Comparison
The new Copilot Mode capabilities closely mirror those showcased by OpenAI Atlas. Key features include:
- Ability to analyze and reason over user’s active browser tabs
- Summarize and compare information across multiple websites
- Perform actions like hotel bookings, form filling, and email unsubscriptions
Striking Visual Similarities
Observers quickly noted the strong resemblance between Edge Copilot Mode and ChatGPT Atlas interfaces. Both feature clean, nearly identical layouts with only minor aesthetic differences – Microsoft opting for darker backgrounds following Windows design conventions, while Atlas prefers macOS styling. Both browsers are built on Google’s Chromium foundation.
The Intensifying AI Browser Competition
While Copilot Mode first appeared in Edge with basic features in July, the rapid deployment of advanced capabilities immediately after Atlas’s announcement reveals Microsoft’s urgent competitive stance. Despite sharing fundamental AI models and Microsoft’s ongoing investment in OpenAI, the browser launches represent a critical battleground for platform control, user data, and internet interface dominance.
Availability and Access
The updated Copilot Mode is available immediately for all Windows 11 Edge browser users. Microsoft has confirmed the feature will also roll out to Edge on Mac systems, followed by the Edge mobile app for both Android and iOS platforms.
