Chrome actually has two kinds of Gemini. One is the “Gemini in Chrome” assistant, which requires you to sign in with a Google account and runs in the cloud. The other is the Gemini Nano model, which runs directly on your computer. The two differ in eligibility requirements, privacy risks, and best uses.
