Microsoft Copilot

What is Microsoft Copilot?

Microsoft Copilot is a generative AI assistant developed by Microsoft, built on OpenAI's GPT-4 and GPT-5 large language models via the Microsoft Prometheus model. Launched in 2023 as the successor to Cortana, it operates across multiple surfaces — a standalone web experience at copilot.microsoft.com, Windows 11, mobile apps (iOS & Android), Microsoft Edge, and deeply embedded within Microsoft 365 applications such as Word, Excel, PowerPoint, Outlook, and Teams. It operates on a freemium model, with a free tier covering core chat and image generation, and a paid Copilot Pro tier ($20/month) unlocking priority model access, advanced reasoning, and early-access Labs features.

Key Features

• Image & Creative Generation

  Generates high-quality images from text prompts via Microsoft Designer's Image Creator (DALL-E 3), supporting visual content creation directly within the chat interface.

• Microsoft 365 Deep Integration

  Embedded natively in Word, Excel, PowerPoint, Outlook, and Teams — drafting documents, building presentations, analyzing spreadsheet data, summarizing emails, and transcribing meetings.

• Copilot Voice

  Supports real-time voice conversations using GPT-4o's audio capabilities, with multiple voice options and a Copilot Daily feature that reads out news, weather, and schedules.

• Actions & Deep Research

  Executes tasks across partnering services (e.g., Expedia, OpenTable) and performs multi-step Deep Research by synthesizing information from across the web into structured reports.

• Memory & Personalization

  Optionally stores user preferences, facts, and routines to deliver increasingly personalized responses and recommendations over time.
