Copilot

Why It Exists

Users need AI assistance for writing, coding, research, and productivity tasks without interrupting their workflow or switching between tools.

How It Works

Microsoft Copilot is an AI-powered assistant that helps users write, research, code, and automate tasks on Windows Copilot+ devices. Using on-device NPU processing for privacy-sensitive tasks and cloud-based models for complex queries, Copilot provides intelligent assistance across the Windows ecosystem. The system can rewrite text, summarize documents, generate code, create presentations, and manage workflows. Copilot integrates with Edge, Office apps, and Windows Search.

Everyday Use Cases

• Text rewriting
• Document summarization
• Code generation
• Presentation creation
• Web research
• Data analysis
• Workflow automation
• Brainstorming

User Workflow

• User activates Copilot via taskbar icon or keyboard shortcut
• Enters a query or request in natural language
• AI analyzes the request and context
• Response or action is generated
• User applies the result or asks follow-up

AI Processing Flow

User input and context are processed by on-device NPU models for basic tasks like text summarization. Complex queries use Microsoft's cloud AI with encryption. Response generation uses large language models. Context awareness leverages open apps and documents. All processing respects user privacy settings and data handling policies.

Inputs / Outputs

Inputs:

• User query
• Active document
• Browser context
• App data
• System information
• User preferences

Outputs:

• AI-generated responses
• Rewritten text
