How to Clear ChatGPT Memory: Step-by-Step Guide

Open Settings > Personalization > Memory to manage or delete saved memories. For a more complete cleanup, also remove relevant chats, Library files, or connected-app access.

To clear saved memories in ChatGPT, open Settings > Personalization > Memory, then delete the items you want removed or use the clear option available on your account. If you also want to remove the information from its original source, delete the relevant chat, Library file, or connected-app access separately. Turning Memory off alone does not delete chats.

Clear saved memories in ChatGPT

  1. Open ChatGPT and select Settings.

  2. Choose Personalization, then Memory.

  3. Review the controls displayed for your account. Depending on your experience, you may see labels such as Memory, Reference saved memories, Reference chat history, Memory summary, Manage, or Saved memories.

  4. Use Manage or Saved memories to review and delete individual items, or select the available clear/delete control to remove saved memories. If your summary offers Delete and turn off memory, OpenAI says this removes the remembered information shown there and turns Memory off; it does not delete past chats.

Settings can vary by plan, region, platform, and workspace. If a control is missing, it may not be available to your account or may be managed by your workspace administrator. OpenAI’s availability guidance

What to delete for a more complete cleanup

A saved memory and the conversation or file it came from are separate. Deleting one does not automatically delete the other, so choose the actions that match what you want removed.

Action What it affects What remains or happens next
Delete a saved memory Stops that saved item from being used for future personalization. References in existing chats remain. Delete the source chat or file separately if needed. OpenAI
Turn off Memory Disables the relevant memory feature. Past chats are not deleted. Turning Memory back on may allow new memories to form from chats still in history. OpenAI
Turn off Reference chat history Stops ChatGPT from using information remembered from past chats for personalization. OpenAI says derived information is scheduled for deletion from its systems within 30 days; original chats remain unless you delete them separately. OpenAI
Delete a chat Removes the conversation from your account view immediately. OpenAI schedules permanent system deletion within 30 days, subject to stated de-identification, security, and legal exceptions. Deletion cannot be undone. OpenAI
Delete a Library file Removes the separately saved file from Library. Deleting the chat where it was uploaded does not remove its Library copy. OpenAI
Disconnect a connected app Prevents future access through that connection. It does not erase past conversations that already used information from the app. OpenAI
Turn off “Improve the model for everyone” Changes whether new conversations are used to improve models. It does not delete saved chats or clear memories. OpenAI

Delete the original chat or file

Delete a chat

Find the conversation in your chat list, open its options, and choose delete. A deleted chat disappears from your account view immediately. OpenAI says it is scheduled for permanent deletion within 30 days, except where it has already been de-identified or must be retained for security or legal obligations. Chat deletion cannot be undone. Deleting and archiving chats in ChatGPT

Check archived chats too if you are looking for a conversation that is not in the main list: archiving is not the same as deleting. If you delete a chat but previously saved a memory from it, remove that memory separately. Memory in ChatGPT

Delete a Library file

If a file was saved to Library, delete that copy in Library as well as deleting any conversation that contains it. The Library file is managed separately from its chat. Using Library to manage files in ChatGPT

Choose the right setting for future conversations

Stop using context from past chats

If your account has Reference chat history, turn it off under Settings > Personalization > Memory. OpenAI says information derived from past chats is scheduled for deletion within 30 days after you turn the setting off, but the original conversations are not deleted by that action. Memory in ChatGPT

Use Temporary Chat

Temporary Chats do not create or update memories while they remain temporary. A personalized Temporary Chat may still use existing memories and custom instructions, so choose the unpersonalized option at the start if you do not want that context used. Temporary Chat FAQ

Do not confuse model improvement with Memory

The Improve the model for everyone setting concerns whether new conversations are used to improve models. It is not the control for saved memories, and changing it does not delete or hide chats. Data controls in ChatGPT
