The Gemini app is an experimental AI assistant that can replace Google Assistant as the primary assistant on your phone. While some Google Assistant voice features like controlling media and routines are not yet available through Gemini, you can easily switch back to Google Assistant in the settings. This official app is currently only available in English in the US on Android phones with 4 GB of RAM or more running Android 12 and up, offering direct access to Google's AI models for various tasks such as writing assistance, summarizing information, generating images, and more.

Gemini provides users with a range of features to enhance their experience, including help with writing, brainstorming, learning, and quick information retrieval from Gmail or Google Drive. Users can also utilize text, voice, photos, and the camera for assistance in new ways, as well as interact with Gemini by saying "Hey Google" to ask for help with on-screen content. Additionally, users can make plans using Google Maps and Google Flights through the Gemini app, with advanced features available for those with access to Gemini Advanced.

The Google Gemini mobile app is gradually rolling out to select locations, languages, and devices. Users can find more information about availability and app requirements in the Help Center. It is important to review the Gemini Apps Privacy Notice to understand how user data is handled within the app.
