Just like on your computer, Gemini on mobile is there to answer questions about what you're reading. On Android it works with anything on your screen* – including Chrome. And coming soon to iOS, Gemini will be built right into the Chrome app.
To open Gemini on Android phones, long-press the power button. On iOS, you’ll soon be able to open it from the Chrome omnibox.
*Available on select devices and in select countries, languages, and to users 18+.
