Microsoft Copilot: The AI Assistant Built Into Windows 11 and Microsoft 365

Microsoft Copilot is an artificial intelligence assistant built directly into Windows 11 and Microsoft 365 applications like Word, Excel, PowerPoint, and Outlook. It can answer questions, help you write and edit documents, summarize long emails, explain data in spreadsheets, and generate images — all without leaving the apps you already use.

The name "Copilot" reflects Microsoft's approach: the AI is designed to work alongside you rather than replace your decision-making. You remain in control of what gets written, saved, or sent. Copilot makes suggestions, drafts content, and explains things. You decide what to keep.

There are two versions of Copilot. The free version is available to anyone with a Microsoft account at copilot.microsoft.com or through the Windows 11 taskbar button. It works like an advanced chatbot. You type questions or requests and it responds with detailed answers. This version can browse the internet for current information (unlike some AI tools that have a knowledge cutoff), generate images through Microsoft Designer, and help with general writing tasks.

The paid version, called Copilot for Microsoft 365, is a subscription (usually $30 per user per month, sold through business plans) that integrates Copilot deeply into Word, Excel, PowerPoint, Outlook, and Teams. With this version, you can open a document and ask Copilot to summarize it, rewrite a section in a different tone, or create a PowerPoint presentation from your written notes. Inside Outlook, it can summarize long email threads and draft replies.

For most home users, the free version available through copilot.microsoft.com or the Windows 11 taskbar is a powerful tool that costs nothing. It handles research, writing help, question answering, and image generation without any subscription.

Copilot in Windows 11 is accessible by pressing the Windows key + C on your keyboard, or by clicking the Copilot icon in the taskbar. It opens as a panel on the right side of your screen, where you can type requests while other windows remain open.
