How to edit Gemini’s Memory summary and delete its source chats
Response preferences, conversation history and future learning need different controls.

Open Gemini and follow Menu > Settings > Personal Intelligence > Memory summary, if the feature is available on your account. You can review and correct its understanding of you there. Removing the original conversations requires a separate action in Gemini Apps Activity.
| Control | Purpose | Appropriate action | | --- | --- | --- | | Memory summary | Inspect Gemini’s understanding of you | Correct or remove a remembered detail | | Instructions for Gemini, also called Saved Info | Set response preferences, including tone and formatting | Choose More > Edit or Delete beside an instruction | | Gemini Apps Activity | Review prompts and conversation activity | Delete individual items or a wider selection |
Use Instructions for Gemini when you want to specify how answers should sound or be formatted. Google says anyone can add instructions; asking Gemini to remember particular information is a separate capability still rolling out. To change an existing preference, open the instructions control and edit that entry rather than hunting through old conversations for the request that set it.
Where to find it
Google lists mobile and web support. Requirements: a personal account, age 18+, Keep Activity enabled and Memory enabled. Its help excludes the UK, EEA, Nigeria and Switzerland.
November’s change gives remembered details a browsable, editable home; Google introduced learning from previous conversations in August 2025. For a direct route to personalization settings, use gemini.google.com/personalization-settings. When 9to5Google reported, it had not yet seen the summary on Android or iOS.
Free-plan users have reported access during the rollout: Tom’s Guide’s writer accessed the feature without a paid Gemini subscription. Official eligibility and observed access differ: 9to5Google described Google AI subscribers using US English, while testers reported access outside those limits. A free plan therefore needn’t stop you checking your settings for the feature.
Android Authority’s writer accessed the summary on the web, outside the US, using a free account. The publication also reports that the summary draws on connected apps such as Gmail and appears only in English. App connections can therefore account for personal details you never typed into a Gemini conversation.
Edit and verify
1. Read the summary and identify the exact detail you want corrected or removed. 2. Ask Gemini to update or remove it—an outdated phone number, for example—or tap the pencil icon, edit the text and select Save. Android Authority describes that direct editing method and also observed a confirmation pop-up for changes through the details text box; 9to5Google covers the editable summary interface. 3. Reopen the summary and inspect the wording that now appears. 4. Check Memory history for when information was added or changed. Then ask Gemini, “Did you use any info from past chats?”, to check whether past conversations informed its response. 5. If you also want the original material removed, follow the source-chat deletion steps below.
In Android Authority’s test, Gemini could no longer answer a question about a removed fact, but it still remembered that a related summary edit had happened.
Delete source chats
Google warns that requests to forget or avoid a topic can be unreliable. Its deletion guidance says to remove every conversation containing the information, so check for repeated mentions. Google doesn’t say whether a detail removed only from the summary can return from old chats, so delete those chats too.
Visit myactivity.google.com/product/gemini. Delete an individual activity item for a targeted cleanup, or select a custom date range to cover a period. Choose Delete > All time when you want to remove all Gemini activity.
Before deleting a pinned or recent chat, review any work inside it. Deleting that conversation also removes its activity entry and content created there, including Canvas documents and apps.
Check branched conversations separately: deleting the original chat leaves its branches intact, and deleting a branch leaves the original intact. If the detail appears in both, include both in your cleanup instead of treating either deletion as covering the other copy.
A shared conversation has another separate control: deleting the chat leaves its public link live. Remove that link too if you want to stop sharing it.
For information originating in a connected app, Google advises deleting chats containing it and disconnecting the app to prevent Gemini finding it again. Changes to connected-app data can take days to affect Gemini.
What happens after deletion: - Activity deletion starts immediately; removal from storage follows. - Gemini may briefly keep using a deleted conversation for personalization. - Conversations already reviewed by humans are exempt from activity deletion. Google’s Privacy Hub says those chats and associated data can remain for up to three years.
Future conversations
To stop future learning while keeping existing chats, switch Memory off under Personal Intelligence. For a set-and-forget activity cleanup, choose automatic deletion after 3, 18 or 36 months.
Turning Keep Activity off changes activity storage, but conversations can still remain associated with your account for up to 72 hours, outside the visible record, according to Google’s activity guidance. Choose that control with the retention window in mind.
For an individual conversation you want excluded from personalization, use Temporary Chats. They stay out of both recent chats and Gemini Apps Activity, and Google excludes them from personalization and AI training. Temporary conversations still have a retention window of up to 72 hours.
