ChatGPT Memory is no longer just a small list of facts that you explicitly ask the assistant to save. OpenAI’s current system can build a changing summary from useful context across chats, files, and connected apps, then use that context to personalize later answers. The same feature can be convenient and easy to misunderstand. Turning memory off, deleting a chat, clearing the memory summary, and disabling model training are separate actions with different results.
This guide explains the controls OpenAI documents in July 2026. It is based on OpenAI’s help pages and release notes, not personal account testing. The interface can vary while updates roll out, so use the labels available in your own Settings page and avoid assuming that another user’s screen will match yours.
What ChatGPT Memory means in 2026
When memory is enabled, ChatGPT may use information from your chats, uploaded files, and connected apps to make future replies more relevant. OpenAI describes the current system as a continually updated synthesis rather than a complete transcript or a fixed notebook. You can review a memory summary, correct it, and delete the memories shown there. The summary can say when it was last updated, but it may not display every detail that affects personalization.
This current experience differs from the legacy saved memories system. Saved memories are individual details that you directly ask ChatGPT to remember, or that ChatGPT saves because they may help in later conversations. They are stored separately from chat history and remain part of future context until removed. The newer memory summary updates more automatically and is meant to avoid the stale or contradictory items that can accumulate in a manual list.
OpenAI still documents a way to return to legacy saved memories through Settings > Memory > Saved memories. The exact controls you see depend on whether the updated experience has reached your account. According to the ChatGPT release notes, memory summary updates were still rolling out across plans and countries in June 2026. That is the safest way to describe availability: documented rollout, not universal visual parity.
Memory summary, saved memories, and past chats are different
The memory summary is a high-level view of what ChatGPT currently considers useful about you. It changes as you keep chatting. OpenAI says the summary should contain the most important details, but it is not a complete ledger. If you want to check whether a particular detail has been remembered, OpenAI suggests asking ChatGPT directly.
Legacy saved memories behave more like persistent notes. You might say, “Remember that I prefer vegetarian recipes,” and ChatGPT can consider that preference later. OpenAI says ChatGPT may also save useful details without an explicit request. You can delete an item, clear all saved memories, or turn the feature off. Deleting the chat where a saved memory began does not necessarily delete that memory because the two are stored separately.
Past chat context is broader. In the updated experience, ChatGPT can synthesize useful information from conversation history rather than relying only on a short list of saved items. This does not mean every past message is inserted into every new prompt, nor does the memory summary show every factor. It means relevant context from previous conversations may influence a response when memory is enabled.
Chat history itself remains a separate account record. You can search and reopen old conversations using the current interface described in our ChatGPT unified search guide. Finding a chat, deleting a chat, and changing memory are three different operations.
How to review and correct what ChatGPT remembers
Open Settings, choose Personalization, then open Memory. OpenAI’s Memory FAQ documents the memory summary and its management options. You can type a requested change into the box below the summary, or highlight text in the summary and make a specific correction. If the summary is empty, the account may be new, memory may have been enabled recently, or there may not yet be enough history. A Refresh option is available from the summary’s menu.
Corrections matter because personalization can be based on context that has changed. A location, work role, diet, current project, or preference may no longer be accurate. State the correction plainly and then review the summary. Do not treat a fluent response as proof that every stored detail has been changed.
OpenAI also provides source visibility beneath personalized responses. Tap the book icon below a response to see sources such as custom instructions, past chats, files, and memories. Selecting a memory can explain why it was used, and the three-dot menu can offer a correction route. OpenAI cautions that this source view may not show every factor that shaped the answer. Memory sources are not included when you share a chat.
Deleting a memory is not the same as deleting a chat
If you delete a chat, a legacy saved memory created from that conversation may still remain. If you delete a saved memory, the old chat can still contain the original statement and earlier replies that mention it. OpenAI says deleted saved memories may be retained in a log for up to 30 days for safety and debugging. Removing a memory also does not rewrite text that already exists in your conversation history.
The current memory summary adds another layer. The “Delete and turn off memory” option deletes the memories shown on the summary page and disables memory, but it does not delete past chats. If you enable memory again later, ChatGPT may form new memories from conversations that still exist, including older chats. That control was available on the web and rolling out on mobile when OpenAI documented it in June 2026.
For a more complete removal, delete every source where the information appears. OpenAI lists past chats, archived chats, files, the memory summary, and connected apps that contain the detail. Disconnecting an app prevents an ongoing connection, while deleting relevant stored material addresses information already present in your account. Check all of these surfaces rather than relying on one toggle.
Turning off training does not turn off Memory
Data Controls govern whether conversations help improve OpenAI’s models. Memory governs personalization. They are related to your data, but they are not the same setting. Under Settings > Data Controls, turning off “Improve the model for everyone” keeps regular conversations in your history while preventing them from being used to train ChatGPT. OpenAI says this preference applies across devices for the account.
Turning off model training does not automatically clear memory or stop past context from personalizing replies. Turning off memory does not necessarily delete chats or change the model-training preference. Review both sections when your goal involves both personalization and training. OpenAI’s Data Controls FAQ is the current source for the training toggle, account export, and related controls.
Custom Instructions are separate again. They are explicit directions about what ChatGPT should know or how it should answer. OpenAI says Temporary Chat still follows enabled custom instructions, even though it does not use or create memories. Review custom instructions if you want a conversation with neither remembered personal context nor standing instructions.
When to use Temporary Chat
Temporary Chat is the clearest option when you do not want a conversation to use existing memories or create new ones. Start a new chat and select the pill-shaped Temporary button in the upper-right corner, as documented in OpenAI’s Temporary Chat FAQ. Temporary chats do not appear in chat history and are not used to improve OpenAI’s models.
Temporary does not mean that no copy can exist. OpenAI may retain a copy for up to 30 days for safety purposes, and limited safety-relevant context may still be used in rare, high-risk situations. If you use a custom GPT with actions, information sent to an outside service is governed by that recipient’s privacy policy and may be kept longer. Temporary Chat cannot override a third party’s data handling.
Use Temporary Chat for a one-off discussion that should not personalize later answers. It is not a reason to paste secrets, medical records, financial credentials, workplace data, or another person’s private information without authorization. The safer rule is to minimize sensitive details before sending them at all.
Sensitive information and practical privacy limits
OpenAI says sensitive information may appear in memory if you share it with ChatGPT. The product controls reduce unwanted reuse, but they do not convert unnecessary disclosure into a good practice. Remove names, account numbers, addresses, passwords, access tokens, health identifiers, and confidential business details when they are not needed for the task.
Connected apps and uploaded files deserve the same attention as typed messages. A memory may be influenced by a file or app even if the detail is not obvious in the visible chat. The source icon can improve transparency, but OpenAI says it may not show every source or factor. If something must be fully removed, inspect the original file, app connection, archived conversations, and memory summary.
For project-based work, keep persistent reference material in a clearly scoped location rather than expecting general memory to act as a document archive. Our guide to ChatGPT project sources explains that separate workflow. Memory is for personalization context, not a guaranteed record of every fact or file.
A short control review
- Open Settings > Personalization > Memory and review the summary available to your account.
- Correct details that are outdated or wrong, then ask whether the specific fact is still remembered.
- Use the book icon under a personalized response to inspect the sources OpenAI exposes.
- Delete both the memory and the original chats, files, or app sources when complete removal is the goal.
- Review Data Controls separately and set “Improve the model for everyone” according to your preference.
- Use Temporary Chat when a conversation should neither access nor create personalization memories.
- Check custom instructions too, since Temporary Chat can still follow them.
Frequently asked questions
Does deleting a chat delete the memory it created?
Not necessarily. Saved memories are stored separately from chat history. Delete the saved memory or summary entry as well as the chat, and remove any other file, archived chat, or connected-app source that contains the same information.
Can I see everything ChatGPT remembers about me?
The memory summary gives a high-level view, but OpenAI says it may not contain every detail or factor used for personalization. You can ask ChatGPT whether it remembers a specific fact and inspect the book icon under a personalized response.
Does turning off “Improve the model for everyone” disable Memory?
No. The Data Controls setting governs model training, while Memory governs personalization. A regular chat can remain in history and still participate in personalization even when it is not used for training, depending on your memory settings.
Is Temporary Chat completely unrecorded?
No. It does not appear in history, use or create personalization memories, or train OpenAI’s models, but OpenAI may keep a copy for up to 30 days for safety. Data sent through a GPT action may follow a third party’s separate retention policy.
What to remember
ChatGPT now combines a current memory summary with context from past conversations, while the legacy saved memories view remains available for accounts that use it. The controls are useful only when you distinguish their jobs. Memory changes personalization. Deleting chats changes history. Data Controls change training preferences. Temporary Chat avoids personalization memory for one conversation, subject to documented safety retention and third-party limits.
