Microsoft Copilot is not a single model—it is a product family that applies generative AI inside search, desktop, Office apps, GitHub, and other surfaces. Behavior and grounding differ by product: some answers lean on web retrieval; others use tenant documents or IDE context.
In AI search discussions, “Copilot” often means the Bing- or Edge-facing assistant that answers natural-language queries with web-backed summaries and links. That surface competes with ChatGPT, Gemini, and Perplexity for answer-engine attention.
Brands evaluating GEO should treat Copilot as a distinct prompt-test target: phrasing, citations, and shopping or local features may not match other engines. See Bing Copilot, Answer Engine, and AI Visibility.
