# Microsoft 365 Copilot

## Microsoft 365 Copilot

AI tool cited as the **failure archetype** of [[concept-ambient-utility]]. Despite sitting inside applications used by **450 million people**, it achieved only **3.3% paid penetration** — because it functions as a **feature that must be consciously invoked** rather than a default path through the work. It is the negative half of the contrast in [[claim-invoked-ai-ignored]] (against [[entity-github-copilot-d4]]).

**Canonical reference:** microsoft.com/microsoft-365/copilot — AI assistant embedded in Word, Excel, PowerPoint, Outlook, and Teams for drafting, analysis, and meeting summaries. (The **3.3% penetration** figure is **not independently verified**, though directionally plausible given enterprise pricing/licensing friction — see [[claim-invoked-ai-ignored]].)
