Microsoft has launched a new feature called Copilot Mode in its Edge browser, marking a strategic move to integrate artificial intelligence more deeply into web browsing. Introduced on July 28, 2025, Copilot Mode transforms Edge into an AI-powered assistant that can analyze multiple open tabs simultaneously, summarize content, and assist users in managing tasks such as booking reservations and handling errands. The mode combines chat, search, and web navigation functionalities to organize browsing into topic-based queries, enhancing productivity and user experience. Initially available for free on Windows and Mac PCs for a limited period, Copilot Mode features multi-tab retrieval-augmented generation (RAG) and built-in actions for task delegation. Microsoft CEO Satya Nadella highlighted the mode as a step toward reinventing browsing for the AI age, with further innovations planned. The feature also includes voice assistance and capabilities to scan, summarize videos, group tabs, and live-translate content. Microsoft is gradually rolling out an advanced Smart Mode powered by GPT-5, designed to adapt its processing speed based on task complexity. This launch positions Microsoft Edge competitively in the emerging AI browser market, which includes other players like Google and OpenAI. Despite Edge's recent decline in popularity, Microsoft aims to revitalize its browser with these AI-driven enhancements.
