Microsoft is starting to test a new experimental Copilot Mode inside its Edge browser today. The AI-powered mode allows Copilot to search across all your open tabs and handle tasks like booking a restaurant, and it brings the Copilot chatbot to your new tab page.

How well it works in practice remains to be seen, but Microsoft notes that Copilot Mode is still considered an experimental feature. It’s also opt-in by default during these tests and is currently free for any Mac or PC users with access to Copilot. There are a few main components to Copilot Mode at launch, with more on the way.

Microsoft is launching a new AI-powered Copilot Mode in its Edge browser, aiming to challenge Google Chrome and compete in the growing wave of AI-enabled web browsers.
