Microsoft Copilot accuracy — and how to verify it independently

Copilot is integrated into the tools you use every day. Making sure what it says is accurate matters more when it's woven into your work.

Common questions

Does Microsoft Copilot fact-check its own responses?

Copilot uses Bing grounding for some queries, which can surface recent information. However, it does not independently verify each factual claim in its responses against primary sources. The same model that generates the response also evaluates the retrieved context.

Does Verol work with Copilot in Edge browser?

Yes. Verol works as a Chrome and Chromium-based browser extension, which includes Microsoft Edge.
