Google launches Gemini desktop app for Mac with window-sharing analysis feature

Google has released a dedicated Gemini desktop app for macOS that brings native desktop integration and window-sharing capabilities to its AI assistant. The app allows users to share and analyze content from any open application or window on their Mac.

System requirements and access

The Gemini Mac app requires:

• Apple Silicon (M1 chip or higher)
• macOS Sequoia 15 or later
• Google account for sign-in

Users can download the app from Google's Gemini Mac app page. The app can be launched via keyboard shortcuts: Option+Space opens a mini chat window, while Option+Shift+Space launches the full window interface. Both shortcuts can be customized in Settings.

Window-sharing functionality

The app's primary differentiator is its ability to analyze content in shared windows. Users can click the plus icon in the prompt area, select "Share Windows," and choose any open window to share with Gemini. The AI can then summarize, answer questions, or provide information about the displayed content.

First-time users must grant the app necessary system permissions to enable window sharing. Google provides user control over which specific windows are shared, though the company advises against sharing sensitive or confidential information.

Feature parity with web version

The desktop app includes all features available on the Gemini website:

• Access to Fast, Thinking, and Pro modes (depending on subscription tier)
• Text and voice input
• File analysis from Mac storage, Google Drive, or Google Photos
• Integration with NotebookLM and Canvas tools
• Image, video, and music generation capabilities
• Chat history and conversation management

Competitive landscape

Google joins OpenAI (ChatGPT), Microsoft (Copilot), Anthropic (Claude), and Perplexity in offering dedicated desktop applications for their AI assistants. However, competing services provide apps for both Windows and Mac, while Gemini's desktop app is currently Mac-only.

Google has separately released a Windows app with similar window-sharing functionality, which can share either the entire desktop or specific windows.

What this means

Google's Mac app represents a shift toward treating AI assistants as native OS-level tools rather than web services. The window-sharing feature creates workflows that weren't practical with browser-based access, particularly for users who frequently need AI assistance while working in other applications. However, the Mac-only release suggests Google is testing desktop integration with a smaller user base before potential wider rollout. The timing follows similar moves by competitors, indicating desktop AI integration is becoming a standard feature category rather than a differentiator.
