ChatGPT memory feature: how to use it (and turn it off)

ChatGPT can now remember things from one chat to the next. Tell it once that you're vegetarian, and it stops suggesting steak in future conversations. Tell it your job once and it gives you more relevant advice. This is the memory feature. It's useful, sometimes intrusive, and easy to control.

What memory actually does

When you start a new chat, ChatGPT loads in everything it remembers about you. The chat then proceeds with that context. Example:

You tell ChatGPT: "Remember that I have a 7-year-old daughter named Emma who loves horses and is allergic to peanuts."

Months later in a fresh chat: "Suggest birthday gift ideas for a kid."

ChatGPT remembers Emma and suggests horse-themed gifts that avoid peanut-containing snacks. You didn't have to re-explain.

What ChatGPT decides to remember on its own

ChatGPT also takes notes silently. When you mention things in passing, it may save them:

• Your job or industry
• Your city or region
• Your interests and hobbies
• Family details (spouse, kids, pets)
• Health conditions you've mentioned
• Projects you're working on
• Your writing style preferences
• Tools you use (Office, Google Workspace, specific software)

When it adds one, you see a small "Memory updated" banner in the chat. Always check what's been saved.

Step 1: Check what ChatGPT already remembers about you

1. Open ChatGPT.
2. Click your name (bottom left).
3. Click Settings.
4. Click Personalization.
5. Click Memory.
6. Click Manage.
7. You see a list of every saved memory.

Read through it. You may find things you forgot you said. Delete anything you don't want stored.

Step 2: Tell ChatGPT what to remember

Just talk to it. Useful starter memories:

• "Remember I'm vegetarian (no meat, but eggs and dairy are fine)."
• "Remember I'm in Watsonville, California."
• "Remember I prefer short, direct answers, not long explanations."
• "Remember I'm 65 and recently retired."
• "Remember I don't like exclamation points."
• "Remember my husband's name is John and he's 70."
• "Remember I'm building a small business called Watsonville Pet Care."

Each gets saved. You don't have to re-establish context in every chat.

Step 3: Edit or remove memories

To remove a single memory:

1. Settings > Personalization > Memory > Manage.
2. Hover over the memory.
3. Click the trash icon.

Or just tell ChatGPT in any chat: "Forget that I'm vegetarian." It removes the memory and confirms.

To clear all memories: same page, click Clear ChatGPT's memory. Wipes everything.

Step 4: Turn memory off entirely

If you'd rather not have memory at all:

1. Settings > Personalization > Memory.
2. Toggle Memory off.
3. ChatGPT no longer saves new memories.
4. Existing memories stay until you delete them.

Temporary Chat (memory-free conversation)

Sometimes you want a one-off conversation that doesn't use or save to memory:

1. In ChatGPT, click your profile icon (top right of the chat).
2. Toggle Temporary chat on.
3. Chat normally. Nothing is saved to history; no memories used or made.
4. When you close the chat, it's gone.

Useful for: sensitive topics, work tasks you don't want mixed with personal context, testing prompts without polluting your memory.

What memory is good for

• Not having to re-explain who you are every time
• Consistent tone and length preferences
• Project continuity (ChatGPT remembers your novel's characters)
• Health and dietary context
• Names of people you mention often
• Your job and industry-specific shorthand

What memory can do badly

• Save things you forgot you said. Mentioned an embarrassing health detail once? It may be saved. Check the memory list.
• Confuse new chats. If you've been writing fiction and ChatGPT thinks you're really a vampire hunter, it'll bring up vampires in unrelated chats. Edit the memory.
• Apply to professional work in distracting ways. Your personal preferences leak into work conversations.
• Make mistakes if you change your situation. Got a new job? Memory still thinks you have the old one.

Privacy considerations

• Memories are stored on OpenAI's servers, linked to your account.
• If you turn off training (Settings > Data Controls), memories are not used to train future models.
• Anyone with access to your account can see your memories. Use a strong password and 2FA.
• If your account gets hacked, the attacker sees everything you've told ChatGPT about yourself. Treat memory the way you'd treat browser autofill: useful but a target.

See our AI privacy guide for the broader privacy picture.

Memory in other AI tools

• Claude: doesn't have automatic cross-chat memory in the same way. Each chat starts fresh unless you use Projects (paid).
• Gemini: has memory called "Saved Info." Manage at gemini.google.com/saved-info.
• Microsoft Copilot: personal memory is rolling out gradually.

5 things to try with memory

1. Open Settings > Personalization > Memory. Read everything ChatGPT has saved. Delete anything outdated.
2. Set up basic preferences: "Remember I prefer short answers. Remember I don't like exclamation points."
3. Tell it your context: "Remember I'm a retired teacher in Santa Cruz County."
4. Use Temporary Chat for a private one-off question.
5. Try a new chat and notice how much more relevant the answers feel.

If memory feels too intrusive

Turn it off. It's a real choice between convenience (ChatGPT knows you) and privacy (you start fresh each time). Both are valid. The toggle is one click.
