Microsoft 365 Copilot is a new AI-powered tool introduced by Microsoft that uses large language models (LLMs) and natural language processing to help users be more productive and creative in their work. Copilot is integrated into Microsoft 365 apps such as Word, Excel, PowerPoint, Outlook, and Teams, providing users with suggestions and prompts that enable them to accomplish their tasks faster and with more efficiency. Copilot can generate a first draft in Word, help create presentations in PowerPoint, summarize emails in Outlook, and suggest action items during a meeting in Teams.
