Installing and Using the Google Gemini Desktop App

The official Google Gemini desktop app provides instant access to Gemini AI directly from your desktop. Rather than opening a browser tab, you can invoke Gemini over any active application using a quick keyboard shortcut, share active screen context, cross-reference data across Google Workspace (Gmail, Drive, Docs, Calendar), and delegate complex tasks to AI agents.
