Michael Friedman, Group Product Manager, Gemini App writing on the Google Blog about the release:

Today, we’re bringing the Gemini app to macOS as a native desktop experience, designed to live right where you work. It’s always just a keyboard shortcut away, so you can quickly get the help you need without losing your focus.

As a native SwiftUI app on Mac, it does a bunch of cool things the web experience couldn’t. It works with your local files, interacts with app windows, and supports Personal Intelligence as well.

Looks like a solid release.
