Google has launched an experimental app for Microsoft's Windows operating system to improve web and file searches. Users can access the search interface using the keyboard shortcut Alt-Space, allowing them to search the Internet, local files, installed applications, and Google Drive. The app features Google Lens for interacting with text and visuals on screens, enabling tasks like translating images or assisting with homework. It also includes an AI Mode for deeper responses and follow-up inquiries. Currently, the app is available to English-speaking users in the United States through Google's Search Labs initiative. Users can opt-in but may have privacy concerns regarding local file access, though permission settings are adjustable. The app's long-term viability remains uncertain.
