Microsoft Copilot for Windows

Microsoft Copilot is an AI‑powered personal assistant built into Windows. Users can enable the optional "Hey, Copilot!" wake word to launch voice conversations without touching the keyboard. The on‑device wake‑word detector runs locally for privacy, while the subsequent AI response is generated in the cloud. Copilot Voice offers a floating UI, chime feedback, and easy end‑of‑conversation controls, helping users stay in flow for quick answers, brainstorming, or task assistance.
