Microsoft Copilot is an AI assistant developed by Microsoft Corporation, evolving from the Bing Chat product launched in 2023 and rebranded as Copilot in 2023-2024. It is built on OpenAI's GPT models combined with Microsoft's own integrations, and is available both as a standalone consumer app and embedded across Microsoft 365 apps like Word, Excel, PowerPoint, Outlook, and Teams, as well as Windows and the Edge browser. Copilot handles conversational Q&A, web search with cited answers, image generation via integrated DALL-E models, and document drafting and summarization. Core features include Copilot Voice for spoken interaction, Copilot Vision for analyzing on-screen content, Pages for organizing chat outputs into editable documents, and deep integration with Microsoft Graph data such as emails, calendar, and files for Microsoft 365 subscribers.
Copilot is used by individuals for general AI assistance and by businesses through Microsoft 365 Copilot, a premium add-on that grounds responses in a company's own documents, emails, and meetings for enterprise productivity.
Microsoft Copilot is available on iOS, Android, Windows, and the web, and built into Windows 11 and Microsoft 365 apps. The consumer app offers a free tier with standard access, while Copilot Pro (around $20/month) adds expanded usage, priority access to advanced models, and integration with Office apps. Enterprise customers license Microsoft 365 Copilot separately, typically priced per user per month on top of existing Microsoft 365 subscriptions.
