Yes. Gemini can use memory of your past chats to personalize answers, according to Google’s Gemini Apps Help, but only if you are 18 or over, sign in with a personal Google Account and have Keep Activity turned on.
As of November 11, 2026, Memory is not available with work, school or supervised accounts, or in Gems and Live chats. It works in the Gemini app, at gemini.google.com, in Gemini in Chrome and on smartwatches. On the web, go to Settings, Personal Intelligence and switch Memory on or off.
Turning Memory off does not delete chats. To remove something Gemini learned, delete every chat that contains it in Gemini Apps Activity. Separately, Google AI plan subscribers in the US can ask Gemini to remember specific facts, such as “Remember that I am vegetarian.” Saved items and instructions last up to 18 months.
