Overview

Microsoft Copilot is Microsoft's AI assistant powered by GPT-4o and integrated across the Microsoft 365 suite — Word, Excel, PowerPoint, Outlook, Teams — plus a standalone web interface at copilot.microsoft.com. It combines web-grounded conversational AI, image generation via DALL-E, and deep Office document editing into a single assistant available to anyone with a Microsoft account.

Key Features

Web-grounded responses with live Bing search for up-to-date answers and citations
DALL-E image generation built in — create images from any conversation without leaving the interface
Microsoft 365 integration lets it draft emails, summarise documents, and build PowerPoint decks from prompts

Pros

• Free tier is genuinely capable — GPT-4o quality with web search, no subscription required
• Best AI option for Microsoft 365 users — the Office integration is deeper than any third-party alternative

Cons

• M365 Copilot enterprise pricing ($30/user/mo) is steep relative to standalone AI tools
• Standalone web interface feels less polished than ChatGPT for pure conversational use
