Microsoft CEO Satya Nadella demonstrated its potential on X, showing Copilot Mode examining various research papers from Microsoft to identify similar points. This capability highlights the mode’s power in synthesizing information from diverse sources.
Today we’re introducing Copilot Mode in Edge, our first step in reinventing the browser for the AI age.
My favorite feature is multi-tab RAG. You can use Copilot to analyze your open tabs, like I do here with papers our team has published in @Nature journals over the last year.… pic.twitter.com/iF0gmbqTSW

Beyond cross-tab analysis, Copilot Mode will support natural voice navigation and introduces a dynamic pane, making Copilot accessible no matter what page you’re Browse. Microsoft is also developing more advanced functionalities. Soon, with user permission for web history and credentials, Copilot Mode will be able to execute actions like booking reservations or proactively suggesting information relevant to a query.

Copilot Mode is currently available for a limited trial period to Edge users on Windows and Mac. Users retain full control and can easily disable Copilot Mode within their browser settings if they prefer.
Microsoft’s move comes as numerous tech companies are vying to dominate the AI-equipped browser market. Competitors like Perplexity, OpenAI, Opera, and The Browser Company are also pushing their AI-integrated products to users. While Microsoft has been aggressively embedding Copilot across its hardware and software ecosystem, the company may still have a significant journey ahead to become a frontrunner in widespread AI tool adoption within the browser space.
