Google Chrome is the leading browser globally, by a wide margin. Although Microsoft has resorted to arguably sneaky tactics in the past in order to win over potential customers, it has faced an uphill battle against Chrome as well as regulators. It seems like Microsoft is now coming around to the idea that even if it can"t upsell Microsoft 365 Copilot to customers through Edge, it should at least try to do it via Chrome.
An entry added to the Microsoft 365 Roadmap today indicates that a Microsoft 365 Copilot extension for Chrome is currently in the works. This will integrate Copilot Search and Copilot Chat directly inside Chrome, allowing users to leverage various functionalities such as summarization of webpages and search results that are grounded within your Microsoft 365 data.
Roadmap ID 530577 reads:
"The Microsoft 365 Copilot browser extension for Chrome brings Copilot Chat and Search directly into the browser, enabling users to ask questions, summarize webpages, and search enterprise content without switching tabs. This improves productivity, reduces context switching, and provides secure, compliant in-browser AI assistance for Microsoft 365 users."
It is worth noting that the use-cases above refer to enterprise environments, but it wouldn"t be surprising to see the consumer version of the AI assistant landing on Chrome eventually too. There is still some time until Microsoft 365 Copilot arrives, as the rollout start date is listed as February 2026.
Keep in mind too that Copilot is already deeply integrated with Microsoft Edge. In fact, at its Ignite 2025 conference a couple of days ago, Microsoft touted Edge as the world"s first secure AI browser for businesses. This is thanks to Copilot Mode and other AI features that you can read more about here. It also took a shot at the competition without naming anyone explicitly, noting that its competitors sacrifice security in order to boost productivity.
