What does the new Gemini app for Windows actually do on your PC?

The shortcut that opens Gemini over any window

Press Alt + Space and a small window appears above whatever you are doing. The announcement says this works at any time. You type a request — a fact check, a title idea, a quick rewrite — and the answer shows up in the same overlay. Close it and you are back in the document or browser you never left.

The mechanism is a global hotkey listener that runs in the background. When the key combination fires, the app draws a layer on top of the active application. No separate workspace opens unless you choose it.

A dedicated workspace for multi-step work

Inside the full app window you get a persistent chat area. The announcement calls out Gemini Spark as a 24/7 personal AI agent that can hand off multi-step tasks. You can also ask Gemini to draft a project summary by pulling information directly from Gmail and Google Drive. That connection means the app authenticates with your Google account and queries those services on your behalf.

The footnote in the announcement states that a Google AI subscription is required, availability varies, and users must be 18 or older. The app does not replace the web version; it adds a native container that keeps the conversation history local to the machine.

Creating images and video from the desktop

Two generation models are named. Nano Banana produces custom images for presentations. Gemini Omni 1 directs high-quality video. Both run inside the same desktop window.

The announcement does not specify resolution limits, length caps, or whether the rendering happens locally or in the cloud. It only says you can do it all in one convenient place. The app is described as lightweight and quiet, running without slowing down the PC. No memory or CPU figures are given.

Availability and what comes next

The download link is gemini.google/desktop. The rollout is global for Windows 10 and 11 starting today.

Google calls this the beginning and promises more native desktop capabilities over time. It does not list a roadmap, a version number, or an auto-update policy. Whether the app will eventually work offline or support local models is not mentioned.
