Microsoft has unveiled a significant upgrade to Notepad in Windows 11, introducing AI-powered summarization and a suite of productivity-enhancing features. This marks the most substantial update to the venerable text editor since its debut in 1983, transforming it from a simple plain-text tool into a modern productivity application.

For millions of users who rely on Notepad for quick notes, code snippets, or temporary document editing, these enhancements could significantly boost productivity without compromising the app's essential character.
