Google has launched a new app for Windows users that enhances the search experience by allowing web, Google account, and local file searches through a keyboard shortcut (Alt + Space). The app features a floating search bar with options to upload files, share screens, and use Google Lens for visual searches. It defaults to AI Mode but allows users to switch to traditional search methods. The app is available globally, but only for Windows 10 and newer systems, and currently supports only the English language.
