In a swift and competitive response to the launch of OpenAI’s new AI browser, Atlas, Microsoft has rolled out significant upgrades to its own browser, Edge, intensifying the battle for AI-driven web traffic.
The update focuses on transforming the existing Copilot functionality within Edge into a full-fledged “AI browser” rival, emphasizing its deep integration into the browsing experience. The move, announced just days after OpenAI’s entry into the space, signals that the browser wars are rapidly shifting from speed and stability to intelligent automation.
The Edge Evolution: Copilot Mode as an “AI Browser”
The new set of features for Edge, branded as an enhanced “Copilot Mode,” aims to make the browser an “agentic” system—one capable of performing complex tasks on the user’s behalf.

Mustafa Suleyman, the CEO of Microsoft AI
Leading the charge for this overhaul is Mustafa Suleyman, the CEO of Microsoft AI. In the announcement, Suleyman made the competitive stance clear, stating: “Copilot Mode in Edge is evolving into an AI browser that is your dynamic, intelligent companion. With your permission, Copilot can see and reason over your open tabs, summarize and compare information, and even take actions like booking a hotel or filling out forms.”
Key features of the Microsoft Edge update include:
- Copilot Actions: This introduces “agentic” capabilities, allowing users to issue natural language commands to the AI to perform multi-step tasks such as unsubscribing from email lists or making a travel reservation.
- Journeys (Preview): This new feature organizes browsing history thematically, grouping past sessions (e.g., all tabs related to “researching smart TVs” or “planning a trip to Italy”) and providing suggestions for the next step, making it easier to resume complex projects.
- Multi-Tab Reasoning: Copilot can now analyze content across all open tabs simultaneously, enabling it to compare details, create syntheses, or provide insights based on a user’s entire browsing context.
Suleyman emphasized that despite the deep integration, the user remains in control, noting, “You’ll always be in control, and I think the transparency creates trust.”
The Challenger: OpenAI’s Atlas
Microsoft’s urgent upgrade comes just after OpenAI, the world’s most valuable startup, unveiled its own browser, ChatGPT Atlas.

Sam Altman, CEO and Co-founder of OpenAI
OpenAI’s browser is centered around its core large language model, promising to supplant the traditional URL bar with a conversational interface. Sam Altman, CEO and Co-founder of OpenAI, introduced the concept by calling it a “rare, once-a-decade opportunity to rethink what a browser can be about and how to use one.”
During the Atlas video presentation, Ryan O’Rouke, the Lead Designer for Atlas, highlighted its key conversational feature, noting that the integrated ChatGPT sidebar is “basically you inviting ChatGPT into your corner of the internet,” allowing the AI to summarize and converse about the specific web page a user is viewing.
The dueling announcements from Microsoft (a major OpenAI investor) and OpenAI (a growing rival) signify that the future of web navigation lies in the intelligence layer, transforming the browser from a simple window to the web into an active, decision-making agent.
