Google has launched the Gemini Windows app to date, bringing its AI assistant out of the browser and onto the desktop for the first time on Windows 10 and Windows 11. The app went live globally on September 10, 2026, following a similar Gemini desktop app launch for macOS back in April, and can be downloaded directly from gemini.google/desktop. Once installed, pressing Alt + Space opens Gemini on top of whatever a user is currently working on, letting them fact-check a document, brainstorm ideas, or generate images without switching windows.The launch puts Google in direct competition with OpenAI's ChatGPT desktop app and Microsoft's own Copilot, both of which already have a native presence on Windows. For a Windows user deciding whether the Gemini Windows app is worth installing, here is a complete breakdown of what it does, how it compares to the alternatives already on your PC, and what Google still hasn't clarified about it.About The AuthorAshna is a content writer who focuses on making everyday choices easier and smarter.
