Microsoft Copilot
Microsoft Copilot is Microsoft's AI assistant family powered by GPT models and Bing search — embedded across Windows, Microsoft 365, GitHub, Edge, and as a standalone chat product at copilot.microsoft.com.
Why it matters
Microsoft Copilot is the AI assistant most enterprise buyers see by default, because it's pre-integrated into the tools their employer already pays for (Microsoft 365). For B2B brands, Copilot share-of-voice often correlates more with closing enterprise deals than ChatGPT visibility does.
What it is
Microsoft Copilot is the umbrella name for Microsoft's AI-assistant products — most powered by OpenAI's GPT models, supplemented by Microsoft's own Bing-derived search index and grounding stack. The Copilot brand spans several products that share UX patterns but target different surfaces.
The Copilot family
- Microsoft Copilot (web) — standalone chat product at copilot.microsoft.com, formerly Bing Chat. Acts as an answer engine over the Bing index.
- Microsoft 365 Copilot — assistant embedded in Word, Excel, PowerPoint, Outlook, Teams, with grounding in the user's tenant data.
- GitHub Copilot — code-completion product for developers, separate roadmap.
- Copilot in Edge / Windows — system-level assistant with screen and tab context.
- Copilot Studio — low-code tool for building custom Copilot agents.
Why it matters for AEO
For brands selling into enterprise IT, marketing operations, finance, or knowledge work, Microsoft Copilot is often the AI assistant employees already have access to — not the one they personally chose. That makes Copilot visibility a leading indicator of consideration in B2B buying contexts.
Measurement notes
Copilot variants surface different answers for the same prompt because of their different grounding (web vs tenant data vs codebase). AEO measurement should target the consumer Copilot product specifically; tenant-grounded responses inside Microsoft 365 are private to each customer and not addressable from the outside.
