How to Use Gemini Memory Summary to Fix What It Knows

Ask Gemini "What do you know about me?" and the answer can be a surprise. Some of it is right, some of it is old, and some of it is from one random chat months ago. Google now gives you a page to check this. It is called Gemini memory summary, and it started rolling out on 9 November.

What is Gemini memory summary?

It is one page that shows what Gemini has saved about you from your chats. Google's own words: you can use it "to view, edit, and delete what Gemini Apps understands about you."

You find it on the web or in the Gemini mobile app under Settings > Personal Intelligence > Memory summary. Early reports from 9to5Google and MobileSyrup say the page groups your details into sections like "The Essentials", "Career & Professional Projects", "Travel & Daily Gear", "Media & Entertainment" and "Fitness & Lifestyle". There is also a Memory history view, so you can see when something was added or changed.

You edit it with normal sentences, for example "Remove my old phone number from your memory." If your request is unclear, Gemini may ask you a follow-up question.

Who it helps most

Freelancers and consultants. If you use Gemini for three clients, it can mix them up. It may still think you work on a project you finished in spring. Old context like this quietly changes your answers.

Software engineers who changed jobs or stacks. Gemini may still believe you write Java at your old company. Then every code answer leans the wrong way. Fixing one line in the summary is faster than repeating "I use TypeScript now" in every chat.

How people are using it

The feature is one day old, so I could not find real user stories yet. The first hands-on look from 9to5Google starts with "The Essentials", a snapshot of your background, location and key relationships. That is the part I would check first.

How to clean up your Gemini memory in 5 minutes

1. Open Gemini and go to Settings > Personal Intelligence > Memory summary.
2. Read each section. Mark anything that is wrong, old or too private.
3. Fix it with a prompt. You can copy this one and change the details:

"Update my memory: I am a freelance designer. My current clients are a bakery and a dental clinic. Forget the logistics project, it ended in May. Remove my home address."

4. Add the facts you want Gemini to always use, for example "Add to my memory that I write in British English and keep emails short."
5. Check Memory history to see that your changes are saved.

Do this once a month.

The honest catch

Right now Gemini memory summary is only for US users, in English, with an active paid Google AI plan, a personal account, and age 18 or older. Keep Activity and Memory must be on. Google's Personal Intelligence features are not offered in the EU, Switzerland or the UK at the moment, so readers here in Germany cannot use it yet. Also, Google says asking Gemini to forget a topic does not always work perfectly, so delete the related chats in Gemini Apps Activity too.
