Microsoft Launches Enhanced Copilot Browser Mode Days After OpenAI’s Atlas

TL;DR: Microsoft has unveiled an enhanced version of Copilot Mode for Edge browser, introducing AI-powered Actions and Journeys features. The announcement came just two days after OpenAI revealed its competing Atlas browser, sparking questions about the remarkably similar timing and functionality.

Microsoft’s latest update transforms Edge into what CEO of Microsoft AI Mustafa Suleyman describes as “an AI browser that is your dynamic, intelligent companion.” The enhanced Copilot Mode can view and reason about open tabs, summarise data across multiple sources, and execute web-based tasks through its new Actions capability.

Key Features and Capabilities

The update introduces two primary features: Actions enable Copilot to complete form fields and book reservations autonomously, whilst Journeys connect information across open tabs to provide contextual insights. Both capabilities position the browser as an active assistant rather than a passive search tool.

The visual implementation places a chatbot interface on the new tab page—a design choice that mirrors OpenAI’s Atlas browser revealed just 48 hours earlier. Whilst both companies maintain their releases were independently scheduled months in advance, the functional and aesthetic similarities have drawn industry attention.

Competition and Differentiation

The timing raises inevitable comparisons between the two products. As Russell Brandom notes in the original reporting, functional similarities are partly unavoidable: “people like clean browsers, and there are only so many ways to integrate a chatbot window into the new tab screen.”

The true differentiation between Microsoft’s Copilot Mode and OpenAI’s Atlas will likely emerge from their underlying AI models rather than interface design. Both companies are positioned to compete on the quality of reasoning, accuracy of task completion, and depth of contextual understanding their respective systems can provide.

Looking Forward

The near-simultaneous launch of competing AI browsers signals an acceleration in the race to integrate generative AI into everyday browsing experiences. For businesses and individual users alike, the competition may drive rapid innovation in AI-powered productivity tools.

The question remains whether users will prioritise interface familiarity, AI model capability, or ecosystem integration when choosing between these emerging platforms. The answer will likely shape the next generation of web browsing technology.
