Microsoft's AI assistant powered by GPT-4, integrated across Windows, Edge, Office 365, and Bing with enterprise-grade security.
Microsoft Copilot represents Microsoft's comprehensive AI strategy, integrating OpenAI's GPT-4 technology deeply across the entire Microsoft ecosystem. What started as "Bing Chat" has evolved into a unified AI assistant embedded in Windows 11, Microsoft Edge, Office 365 apps (Word, Excel, PowerPoint), Teams, and more. For Microsoft 365 Copilot subscribers, it can attend meetings, summarize emails, generate presentations, and analyze Excel data—all while maintaining enterprise-grade security and compliance. The free tier of Copilot, accessible via Bing.com or the Edge sidebar, offers GPT-4 capabilities at no cost—making it one of the most generous free AI offerings available. It includes web search by default (unlike ChatGPT's plugin), can generate images via DALL-E 3, and provides source citations for factual queries. The integration with Microsoft Edge enables Copilot to understand and interact with the webpage you're viewing—summarizing articles, answering questions about content, or even helping compose emails based on webpage context. For enterprise users, Microsoft 365 Copilot ($30/user/month) unlocks transformative productivity features: drafting entire documents from brief prompts, creating presentations from Word outlines, transforming natural language into Excel formulas, or summarizing Teams meetings with action items. Microsoft's advantage is trust: conversations stay within your enterprise tenant, comply with existing data governance policies, and never train public models. However, the consumer experience remains somewhat disjointed across different Microsoft properties, and Copilot occasionally feels more like a feature than a cohesive product compared to ChatGPT's unified experience.
