Microsoft Copilot is a set of new features that combine large language models with existing Microsoft products, aiming to save time and provide an integrated experience. It offers generative AI capabilities, text and data analysis, and more, across various apps including Windows 11, Bing Search's AI Chat, Microsoft Edge, Microsoft 365 apps (Word, Excel, PowerPoint, Outlook, Teams), and others. The features are spread out across the apps, requiring an internet connection to access Copilot. Most of the AI features in Windows, Search, and Edge are free for now, while unlocking add-ons in Microsoft 365 requires a paid subscription. Users can interact with Copilot using voice commands, chat experiences, or prompts within various apps, generating text, images, and data insights. The feature is improving quickly, but most of its capabilities are still in preview mode.
