Microsoft has debuted a Copilot Mode for its Edge web browser. When enabled, this experimental feature can search across multiple open browser tabs and analyze the information on each page. An example posted on X by Microsoft CEO Satya Nadella shows Copilot Mode examining several papers published by the company's researchers and assessing if they make any similar points.
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— Satya Nadella (@satyanadella) July 28, 2025
This feature will also support natural voice navigation and adds a dynamic pane for Copilot to be available wherever you're browsing. The company is working on more advanced options as well. For instance, if you grant it permission to access your web history and credentials, Copilot Mode will "soon" be able to execute actions such as booking a reservation or suggesting whatever the chatbot deems as relevant information to a query. Copilot Mode will be available for a limited time for users with Edge on Windows or Mac machines to try out. If those people prefer, they can also turn Copilot Mode off in their browser settings.
Many tech companies have set their sights winning the race to have an AI-equipped browser. Perplexity, OpenAI, Opera, and The Browser Company have been pushing to get their products in front of users. Although Microsoft has been putting Copilot in both hardware and software, the business may have a ways to go to become a frontrunner in adoption of its AI tools.
