Open Personalization → Memory
In ChatGPT Settings, choose Personalization, then open Memory.
Clear your memory
You can remove individual saved memories or wipe them all from one place — Settings → Personalization → Memory → Manage memories. This guide walks through both, explains how telling ChatGPT to "forget" works, and clears up a common trap: deleting a chat doesn't always delete the memory it created.
Quick answer
You can delete a single item, clear everything, or ask ChatGPT to forget something mid-conversation. They all start from the saved-memories list.
| Method | How | Best for |
|---|---|---|
| Delete one memory | Settings → Personalization → Memory → Manage memories, then delete the item. | Removing a single outdated or wrong fact. |
| Clear all memories | In Manage memories, use the clear-all option. | A clean slate or a privacy reset. |
| Ask in chat | Tell ChatGPT to forget a specific thing, then confirm in Manage memories. | Quick removal without opening settings. |
Deletion and retention timelines are described on OpenAI's help center. Always confirm on OpenAI's Memory FAQ and Data Controls FAQ.
Step by step
The flow is the same on desktop and mobile, though labels can differ. If your screen looks different, check OpenAI's help center.
In ChatGPT Settings, choose Personalization, then open Memory.
This shows the list of saved facts ChatGPT has stored about you.
Delete a single item to remove just that fact, or use the clear-all option to wipe the whole list.
Tell ChatGPT to forget something, then reopen Manage memories to confirm it's actually gone.

Common traps
| Question | What to know |
|---|---|
| Does deleting the chat delete the memory? | Not necessarily. A saved memory persists even if you delete the conversation it came from — delete the memory separately in Manage memories. |
| Does deleting affect chat history recall? | Deleting saved memories doesn't touch the implicit layer. To reduce it, turn off "Reference chat history" and delete old conversations. See saved vs chat history. |
| Is it gone from servers right away? | Deletion stops ChatGPT referencing it; exact retention timelines are on OpenAI's help center. |
| Why does it keep coming back? | If memory is on, ChatGPT may re-save similar facts later. Consider turning saved memories off. |
If memory worries you
Memory is convenient, but it concentrates your personal context inside one company's servers. If you'd rather spread your usage — and pick which model sees which prompt — a multi-model workspace gives you that choice while you keep sensitive topics in memory-free sessions.
Use ChatGPT, Claude, Gemini and other models in one place — choose where each prompt goes instead of feeding everything to a single assistant.
Privacy-first: MultipleChat doesn't save your chats to memory and doesn't share your data with model providers or let them train on it. Other privacy-focused options include Duck.ai, Proton Lumo, Brave Leo and Kagi Assistant; for full local control, self-hosted tools like Ollama or Jan keep everything on your device.
OpenAIOffers Temporary Chat (no history, not used for training), a training opt-out under Settings → Data Controls, and editable memory. By default, consumer chats may be used to improve models unless you opt out — verify on OpenAI's help center.
AnthropicAnthropic gives you data and training controls and has historically taken a privacy-conscious stance on consumer chats, but its training and retention settings have changed over time — check your current privacy settings in the app.
GoogleGemini Apps Activity lets you pause history and delete past activity, but sampled conversations can be reviewed by humans, so avoid sharing confidential information. Review your Activity controls.
MicrosoftMicrosoft 365 Copilot (business) doesn't use your organization's data to train models and adds Enterprise Data Protection; consumer Copilot has a privacy dashboard to review and delete your history. Check current Microsoft policies.
PerplexityPerplexity has an "AI data retention" setting you can switch off so your searches aren't used to improve its models, plus account-level data controls. Confirm the current options in settings.

FAQ
Individual vs all, telling ChatGPT to forget, and the chat-vs-memory trap.
Go to Settings → Personalization → Memory and open "Manage memories." From there you can delete individual saved memories or clear them all. You can also tell ChatGPT in chat to forget something. Verify the current steps on OpenAI's help center.
Open "Manage memories" in Settings → Personalization → Memory, find the specific item in the list, and delete it. That removes it from what ChatGPT references going forward.
In "Manage memories" there is an option to clear all saved memories in one step. This empties the saved-memories list; it does not by itself change your chat-history toggle.
Yes. You can ask ChatGPT in a conversation to forget a specific fact. It is good practice to then open "Manage memories" and confirm the item is actually gone.
Not necessarily. A fact saved to memory persists in the saved-memories list even if you delete the conversation it came from, so delete the memory separately. Deleting conversations does, however, reduce what "Reference chat history" can draw on.
Turning off "Reference saved memories" stops ChatGPT from using stored facts but keeps them. Deleting actually removes them from the list. Use deletion when you want the data gone, not just unused.
Deleting a memory removes it from what ChatGPT references, but deletion and retention timelines are described on OpenAI's help center. Check OpenAI's documentation for exactly how long deleted data may persist before it is purged.
Deleting saved memories does not affect the chat-history layer. To reduce implicit recall, turn off "Reference chat history" in Settings → Personalization → Memory, and consider deleting old conversations.
If memory is still on, ChatGPT may save a new, similar memory during later chats. After deleting, avoid restating the fact, or turn off saved memories if you do not want new ones created. Verify behavior on OpenAI's help center.
