On 10 September, Google introduced Gemini for Windows 10 and later. You can open the app with the Alt and Space keyboard shortcut, giving you a quick route to help without first finding a browser tab.
Google highlights working with images, research and connections to its other apps. What you can use depends on your account, settings and how the features are rolled out.
In everyday use, the big change may be quite small: less friction when a question comes to mind. You might want to understand a term, get suggestions for a heading or think through the next step in a project of your own.
It is also part of a broader shift towards AI moving closer to what we already do on our computers. If you try the app, choose one recurring task first. That makes it easier to notice whether the shortcut actually helps.
