Overview
Microsoft 365 (formerly Office) is a subscription-based productivity platform that combines familiar applications like Word, Excel, PowerPoint, and Outlook with cloud services including OneDrive, Teams, and Planner. The suite now integrates Copilot, an AI assistant built directly into these apps to help users create content, analyze data, and collaborate more efficiently.
With Copilot, users can describe what they want in plain language and receive AI-assisted help across documents, presentations, spreadsheets, and email. The platform offers both free web-based access to core apps and premium desktop versions with additional features. Microsoft emphasizes user control over AI features, which activate only when explicitly chosen.
