Microsoft is updating its Notepad application by enhancing the integration of AI through the Copilot feature, introducing a "streaming" capability that allows users to see text generated in real-time. This feature is currently being rolled out exclusively for Copilot+ PCs but will eventually extend to all regular PCs capable of running Windows 11. The AI integration in Notepad is designed to be an optional feature, though it is turned on by default, allowing users to access functions like Write, Rewrite, Customized Rewrite, and Summarize. Users can disable the AI functionality by going to Settings > Copilot, although the Copilot components will remain embedded within the application.
