Google's AI assistant "Gemini" is now available as a desktop app for Windows. Press Alt+Space and Gemini appears as an overlay on top of whatever you're working on — no browser required. With deep integration into Gmail and Google Drive, it can meaningfully speed up everyday work.

What Is Gemini for Windows?

Gemini for Windows is the official desktop app Google released for Windows 10/11 on September 10, 2026.

以前
Before: Gemini required opening a browser and navigating to Gemini.google. Switching away from your current task to use it was a friction point.
現在
Now: Press Alt+Space and Gemini appears as a floating overlay on top of your current app. Ask questions instantly without opening a browser.

It supports Windows 10 and later, on both x86 (standard Intel/AMD PCs) and Arm (power-efficient processors found in devices like the Surface Pro). That means Arm-based PCs are fully supported right out of the box.

What Can You Do with Alt+Space?

Once installed, pressing Alt+Space brings up a floating overlay on your screen. It appears on top of whatever window you're currently using, so you can ask Gemini questions without breaking your workflow.

A practical example:

Open a document, press Alt+Space, and type "Give me 5 title ideas for this document." Gemini responds immediately with suggestions — no need to close the document or switch tabs.

Alt+Space instant launch + Gmail/Docs integration via Gemini Spark are the standout strengths.

This overlay approach is similar to what Perplexity's desktop app introduced. Google differentiates itself by adding deep integration with its own suite of services.

Gemini Spark: Integration with Google Apps

Gemini Spark is a personal AI agent feature that connects with Gmail, Google Docs, Google Drive, and Google Calendar. It can handle multi-step tasks automatically.

For example, ask it "Pull action items from last week's emails and organize them into a task list." Gemini reads your Gmail, extracts the relevant information, and builds the list for you. What used to require manually opening emails one by one now takes seconds.

ServiceWhat You Can Do
GmailSummarize emails, draft replies, extract action items
Google DocsDraft documents, summarize content, generate title ideas
Google DriveSearch files, review document contents
Google CalendarCheck schedules, suggest meeting times
注意
A Google account linked to your Windows account is required. Google Workspace accounts require additional setup by an admin.

If your organization uses Google Workspace, setup differs from personal Google accounts. Check with your IT team before rolling it out.

Create Images and Videos Too

Gemini for Windows goes beyond text chat with creative capabilities built in.

Nano Banana (image generation) lets you create custom images by describing what you want. Type something like "an illustration of a cat drinking coffee under a blue sky" and it generates the image. It's useful for quick thumbnails, presentation visuals, or social media graphics.

Gemini Omni (video generation) lets you create short video clips directly from your desktop. Describe the scene and Gemini generates a clip — no video editing software needed for simple content creation.

Free vs. Pro: What's the Difference?

ヒント

Summary

The two standout features of Gemini for Windows are Alt+Space instant access and Gemini Spark's Google app integration. Being able to layer AI on top of your current work — without switching to a browser — makes a real difference in day-to-day use. It's free to get started with a Google account, so Windows users should download and try it.
