How ChatGPT’s Memory Changes Its Answers — And How to Control It

How ChatGPT's memory feature affects the answers you get

ChatGPT no longer relies on a one-off "remember this" command. It now collects and refines background information about you automatically, then uses that context in every reply. That can make responses more tailored — for example, avoiding recipe suggestions with meat if it has stored that you're vegetarian — but it can also produce unwanted assumptions, like thinking you live somewhere because you researched nearby restaurants.

When the memory feature launched in April 2024 you had to tell ChatGPT to remember things explicitly. After an update in June the app switched to a model described as "dreaming": memories are gathered and edited over time, and they're flexible rather than locked to their original wording. The system tries to keep memories current — so a planned event can shift to the past automatically — and it decides what to save without you flagging every detail.

Because the app continually updates a profile of you, every response is framed by that profile. That can speed up workflow and cut down on repetitive context you'd otherwise have to repeat. The downside is less control: transient searches or a short research session can change how the app frames later replies unless you correct or remove those items.

On the web app: click your profile icon (bottom left), choose Personalization, then scroll to Memory. On mobile: open the menu (top left), tap your profile icon, then Memory.

The Memory section presents a summary of what the app thinks it knows — items like interests and preferred answer styles.

How to edit or remove specific memories

Open Manage next to Memory summaries to review the stored items. You can highlight any entry and pick Make a correction or Don't mention this again to change it. There's also a prompt box where you can type direct commands such as "forget that I'm a journalist." Those edits change what the app uses when composing replies.

How to delete all memories or stop the feature

A privacy-friendly alternative: temporary chats

If you need a session that won't be stored, use a temporary chat. On the web, click the dotted speech bubble (top right) to start one. Temporary chats are not committed to memory and are forgotten when closed.

• To check what ChatGPT remembers: Profile > Personalization > Memory.
• To correct or hide a specific item: Manage > highlight item > Make a correction or Don't mention this again.
• To delete all memories: Memory > three dots > Delete, then turn memory off.
• To avoid remembering any single session: use a temporary chat.

If you want more tailored replies with less manual repetition, keep memory on and edit entries you don't like. If you prefer full control over context or want to avoid accumulated assumptions, either use temporary chats or delete and disable memory.
