Microsoft Copilot vs ChatGPT
Both are conversational AI assistants, but they live in different ecosystems. Microsoft Copilot is embedded in Microsoft 365 (Word, Excel, PowerPoint, Outlook, Teams) and the web/Edge/Windows experience; ChatGPT is a standalone assistant with a broad feature set including projects, custom instructions, and image generation. There is no universal winner — choose by task and ecosystem. Independent educational content. Features and pricing may change. Last reviewed: 2026-07-24.
