Microsoft Copilot

Microsoft Copilot is Microsoft's AI assistant. It runs in a browser at copilot.microsoft.com, inside the Edge browser and Windows, and in mobile apps, signed in with a free Microsoft account. It is built on OpenAI's models and answers plain-language requests: drafting and editing text, explaining things, brainstorming, and generating images.

It is broadly useful for everyday writing and questions, can search the web for current information, and creates images from text prompts. Because it is Microsoft's own assistant, it also appears throughout the Windows and Edge experience, and — on the paid, work-oriented plans — inside Microsoft 365 apps such as Word, Excel, and Outlook.

It fits people already on Windows or in the Microsoft ecosystem who want an assistant a click away, as well as anyone who wants a free, capable chatbot with web search and image generation built in.

To start, go to copilot.microsoft.com and sign in with a free Microsoft account — no credit card for the free tier. Signing in generally raises your limits compared with using it signed out.

The honest limits. Free usage has caps and can slow or queue at busy times; the most generous limits and the Microsoft 365 integrations belong to paid Copilot offerings (consumer Copilot Pro and business plans), which are separate products with their own pricing. Copilot can be confidently wrong, so check anything important. Exactly which features appear, and where, changes often and varies by country and by whether your account is personal or managed by an organisation.
