Microsoft Copilot
FreemiumAI assistant across Microsoft 365
About Microsoft Copilot
Microsoft Copilot is Microsoft's AI assistant powered by OpenAI's GPT-4o models, embedded across Windows, Bing, Edge, and Microsoft 365. Pricing: free (Copilot in Windows and Bing, GPT-4o access), $20/mo Copilot Pro (priority access, M365 integration), $30/user/mo Microsoft 365 Copilot (enterprise, requires existing M365 E3 or E5 license). The differentiating value is Microsoft 365 integration — Copilot summarizes Outlook emails, generates PowerPoint slides, writes Excel formulas, drafts Word documents, and searches Teams conversation history. The enterprise version can query SharePoint content with privacy guardrails. As a standalone assistant at copilot.microsoft.com, it's functionally a GPT-4o wrapper with Bing search grounding — comparable to ChatGPT but with web search on the free tier. Reddit enterprise IT teams note that M365 Copilot requires careful data governance setup before deployment; without proper permissions, sensitive content surfaces unexpectedly. For non-M365 users, there's little reason to choose Copilot over ChatGPT directly.

Our Verdict
Copilot's value is almost entirely the M365 integration. If your organization runs on Outlook, Teams, and SharePoint, the $30/user/mo can justify itself quickly. As a standalone chatbot, it's just GPT-4o with a Microsoft wrapper — use ChatGPT directly instead.
