What Microsoft 365 Copilot is and where things live

• Copilot is Microsoft's AI assistant for work. You type a request, called a prompt, and it writes, summarizes or answers in plain language.
• Open it at copilot.cloud.microsoft, in the Microsoft Copilot app, or with the Copilot icon in Outlook, Teams and Edge. Sign in with your work account.
• Check the label next to your name in the left pane. Work and a green shield mean enterprise data protection: your company's contract with Microsoft covers your prompts and answers.
• Most work accounts get Copilot Chat, which answers from the web and from files you add. A paid Microsoft 365 Copilot license also reads your email, meetings and files for you.
• At home you might use Copilot on a personal Microsoft account, with or without a Microsoft 365 Personal or Family plan. It shows Personal, so keep work data out of it.
