ChatGPT Memory is the profile ChatGPT keeps about you across chats. Since OpenAI's Dreaming update, which began rolling out on June 4, 2026, that profile is synthesised in the background from your past conversations and revised over time, not only built from facts you asked ChatGPT to save. Memory lives in Settings, Personalization, Memory: one Enable memory toggle, a Manage button that opens your Memory summary, and a Delete and turn off memory command in the summary's three-dot menu. Your older saved memories stay reachable from a link in the same panel. You can read the summary, correct it by typing into its Ask or update box, delete it, or turn memory off, and Temporary Chat keeps a single conversation out of memory altogether. Memory and model training are separate settings. OpenAI states that the memory summary you can see does not include everything ChatGPT remembers. Verified September 9, 2026.
How to Manage ChatGPT Memory: View, Edit, Delete (2026)
Memory is one of the most-asked-about ChatGPT features in AI engine queries and one of the least visible inside the UI. The panel is buried two clicks deep in Settings, the per-row controls only appear on hover, and ChatGPT rarely confirms when it has saved something. This guide walks through every Memory control with screenshots taken on September 9, 2026, explains how Memory differs from Custom instructions and Training data, and shows how AI Toolbox (formerly ChatGPT Toolbox) complements Memory by letting you export and back up the conversations that built your context and search across all of them, since native memory is account-level and cannot be exported on its own. With 40,000+ active users and a 4.7/5 Chrome Web Store rating, AI Toolbox is the most installed productivity layer for ChatGPT.
What Is ChatGPT Memory?
Memory is the layer that lets ChatGPT carry what it knows about you from one chat to the next. Until June 2026 it was a list of discrete saved memories, written when you told ChatGPT something durably useful or asked it to remember. OpenAI's Dreaming update, announced on June 4, 2026, changed the mechanism: a background process now reads your past conversations, synthesises a profile of you, and keeps revising that profile as time passes. OpenAI now labels the older saved-memories system legacy, although saved memories still exist alongside the synthesised profile. Whatever ChatGPT holds persists across sessions, devices, and the apps that share your OpenAI account. OpenAI documents the current behaviour in its Memory FAQ and in the Dreaming announcement.
Memory operates separately from Custom instructions and from the data-training toggle. Custom instructions is a single static text block that applies to every new chat. Memory is dynamic: it is updated as ChatGPT learns about you, and you can correct or remove what it holds. Whether your data trains future OpenAI models is controlled by a separate switch in Settings, Data controls.

One Toggle Now, Two Systems Underneath
From April 10, 2025 until the Dreaming rollout, memory had two switches: saved memories, the explicit facts you asked ChatGPT to keep, and reference chat history, which let ChatGPT draw on past conversations even when nothing was saved. OpenAI extended reference chat history to Free users on June 3, 2025. As of September 9, 2026 the Personalization panel shows a single Enable memory toggle, described as personalizing your experience from your chats, files, and connected apps, and that toggle governs the synthesised profile Dreaming maintains: a background process runs after conversations end and writes inferences drawn from them, not only facts you stated outright. The older saved-memories list has not disappeared. The panel says you can still manage your old saved memories through a link, and OpenAI's Memory FAQ describes enabling or disabling that legacy list on its own. So there is one switch to check first, and a second, older list to check if you used memory before June 2026.
The profile also rewrites itself as time passes. OpenAI's own example from the Dreaming announcement: a memory reading "You're going to Singapore in July" revises itself to "You went to Singapore in July 2026" once the trip is over, without you editing anything. That is useful for a travel plan and worth knowing for anything sensitive, because ChatGPT can hold a conclusion about you that you never typed.
For a single conversation you want kept out of all of this, use Temporary Chat. OpenAI states that temporary chats do not appear in your history, do not use or create memories, and are not used to train its models; OpenAI keeps a copy for up to 30 days for safety purposes and then removes it. It is the cleanest answer to "do not remember this."
How to Open ChatGPT Settings
Click your profile avatar in the bottom-left of ChatGPT, then select Settings from the dropdown menu. The avatar dropdown also holds the My GPTs, Customize ChatGPT, Help, and Log out entries. Settings is the third row in the standard menu. On the web app, the Settings dialog opens in a centered modal. On the desktop app, Settings opens as a native sidebar panel; the contents are identical.
The Settings dialog has a left sidebar of categories, starting General, Notifications, Personalization, with Data controls further down. Memory lives under Personalization, the third entry from the top, below the custom-instructions fields such as More about you.
Toggle Memory On or Off
In Settings, Personalization, the Memory section has one switch, Enable memory, with the description "Let ChatGPT personalize your experience based on your chats, files, and connected apps." It was on by default on the account photographed for this guide. Flip it off and ChatGPT stops personalizing replies from what it has learned. The toggle does not delete the underlying memory; deletion is a separate command on the summary page, covered below. Flip it back on and the same profile is used again.
The toggle is the right control if you want to test how ChatGPT responds without personalization, or if you want to pause memory during a privacy-sensitive task. For a single conversation, Temporary Chat is simpler. To remove the data, use Delete and turn off memory (see the delete-everything section below).
View Your Memory Summary
Click Manage next to Memory summary to open the page titled Memory summary. It is written as prose, not as a list: an Updated timestamp sits beside the title, the body is organized under headings such as Overview and Products, and an Ask or update box runs along the bottom. On the account photographed for this guide the Overview read like a short biography, naming role, products, languages, and audience, several of which had never been typed into ChatGPT as a "remember this" request. There is no filter, sort, or search; the only navigation is scrolling.
Treat what you see as a summary, not a complete record. OpenAI's Memory FAQ states that the memory summary should capture the most important details but will not include everything ChatGPT remembers from your chats, and OpenAI's May 5, 2026 post on GPT-5.5 Instant says its models may not show every factor that shaped an answer. If a reply surprised you with a personal detail you do not remember sharing, the source may be a saved memory, the synthesised profile, or reference chat history, and it may not be listed. Re-read the summary every few weeks if you use ChatGPT for sensitive work, and correct or delete anything that should not carry over between projects.
What the Memory View Does Not Show
This is OpenAI's published caveat, not a third-party accusation: the memory summary is a curated view of a larger synthesis, and some of what ChatGPT remembers is not displayed. The Memory FAQ says the summary "will not include everything that ChatGPT remembers based on your chats", and OpenAI's May 5, 2026 note on GPT-5.5 Instant says the model "may not show every factor that shaped an answer". Tom's Guide reported the same acknowledgement on June 18, 2026, adding that details can be left out when ChatGPT judges them less relevant or not appropriate to show. OpenAI's stated mitigation is that personalised replies now cite their memory sources, so you can see which saved memory or past chat shaped a specific answer and correct or delete it from there. The practical rule: if a detail must not influence ChatGPT, delete it and turn memory off rather than assuming its absence from the summary means it is gone.
Correct or Remove a Single Detail
Type the change into the Ask or update box at the bottom of the Memory summary, for example "Remove the note about my audience size" or "Update my role to senior content lead", and send it. The summary is rewritten and its Updated timestamp changes. OpenAI's Memory FAQ also describes highlighting text in the summary to make a specific correction. There is no per-row trash icon any more, because there are no rows. The original conversation transcripts in your chat history are unchanged either way.
For memories written before June 2026, open the saved memories link in the Memory section; that legacy list is managed separately and is described in OpenAI's Memory FAQ. Use corrections to prune details that drifted out of date, are wrong, or belong to a finished project: old job titles, abandoned product names, a tone you no longer want, and personal details you would rather not have ChatGPT reference. For a clean slate, jump to the next section.

Delete Everything and Turn Memory Off
Open the three-dot menu beside the Memory summary title and choose Delete and turn off memory. The menu has only two items, About memory and that red delete command. It removes the memories shown on the summary and switches memory off in one step, which is why there is no separate Clear all button any more. To start collecting memory again afterwards, switch Enable memory back on in Settings, Personalization.
Delete and turn off memory is the right control when you want a clean slate, for example when handing the account over to a new role, switching from personal to work use, or recovering from a chat session where ChatGPT saved entries you did not want. The action cannot be undone from your side. OpenAI's Memory FAQ notes that it may retain a log of deleted saved memories for up to 30 days for safety and debugging purposes, after which they are gone.
Memory vs Training Data: Two Different Toggles
Memory and the model-training switch are independent. Memory controls whether ChatGPT remembers facts for your own replies. The model-training control (Settings, Data controls, Improve the model for everyone) controls whether your conversations and memories can be used to train future OpenAI models. Turning off Memory does not opt you out of training. Opting out of training does not stop ChatGPT from saving memories for your own use.
If you want full privacy: use Delete and turn off memory on the summary page, check the legacy saved memories link, then open Settings, Data controls, and turn off Improve the model for everyone. With both switches off, ChatGPT operates without personalization and your conversations do not feed training. For a deeper walk-through of every data-controls switch, see the ChatGPT limits and controls guide.
Force ChatGPT to Remember Something Specific
Start the message with "Remember that..." or "Save this to memory:..." to force ChatGPT to write a specific entry. ChatGPT replies with a Memory updated indicator under the assistant message when it has saved the fact. Without the explicit instruction, ChatGPT decides on its own what to keep, and since Dreaming that decision is no longer limited to facts you stated outright: a background process runs after a conversation ends and writes inferences drawn from it into your profile. A casual mention may not produce a saved memory row, yet it can still shape the synthesised profile.
The same syntax works for editing or replacing an existing memory. If a saved row is wrong, send a message like "Update the memory about my role to: senior content lead at AI Toolbox". ChatGPT writes a new entry that supersedes the old one. Check the Memory summary afterwards to confirm the old detail is gone; if it lingers, send a correction through the Ask or update box.
How AI Toolbox Extends ChatGPT Memory
AI Toolbox does not change Memory itself; ChatGPT keeps building and applying your profile exactly as described above. Native memory is account-level and cannot be exported on its own: OpenAI's data export ZIP contains conversations.json, chat.html and your uploaded files, but not your memory. Saved memories have to be copied out of Settings by hand, and the profile Dreaming synthesises has no readable export at all. AI Toolbox complements memory by letting you export and back up the conversations that built that context and search across all of them. It runs as one unified Chromium install (Chrome, Edge, Brave, Opera, Arc) on top of the native ChatGPT interface.
Export and back up the source conversations as TXT, Markdown, JSON, or PDF, so the chats that taught ChatGPT each memory have a local copy you control.
Full-text search across your active ChatGPT conversations (archived chats are not indexed), including the messages where ChatGPT saved a memory in the first place. Use Cmd+Shift+F (Ctrl+Shift+F on Windows) to search by message content, role, or date range with exact-match toggle.
File memory-heavy chats into folders to group them by project. Folders use search-based adding: you search the conversation list and add the matches to the folder, no drag-and-drop required.
AI Toolbox is also available for Gemini and Claude as part of the same unified install. The Gemini module adds full-text search across every synced Gemini conversation with date, role, and exact-match filters. The Claude module adds full-text search with exact-match toggle and message-level bookmarks. Pricing details are on the AI Toolbox pricing page.
Frequently Asked Questions
What is ChatGPT Memory?
Memory is the profile ChatGPT keeps about you across chats, covering things like your preferences, ongoing projects, and writing style. Since OpenAI's Dreaming update, rolling out from June 4, 2026, a background process synthesises that profile from your past conversations and revises it over time, on top of the saved memories you explicitly ask for. You review it in Settings, Personalization, Memory, and OpenAI states the summary shown there does not include everything ChatGPT remembers.
How do I see what ChatGPT remembers about me?
Click your profile avatar, open Settings, go to Personalization, and click Manage next to Memory summary. A page titled Memory summary opens with an Updated timestamp, prose sections such as Overview and Products, and an Ask or update box at the bottom. OpenAI states the summary does not include everything ChatGPT remembers. Older explicit memories are behind the saved memories link in the same panel.
How do I delete a single ChatGPT memory?
Open the Memory summary (Settings, Personalization, Manage) and type the change into the Ask or update box, for example "Remove the note about my audience size". The summary is rewritten and its Updated timestamp changes; OpenAI's Memory FAQ also describes highlighting text in the summary to correct it. There are no rows or trash icons any more. Memories from before June 2026 are managed through the saved memories link instead.
How do I wipe all ChatGPT memories at once?
Open the Memory summary, click the three-dot menu beside its title, and choose Delete and turn off memory. That single command removes the memories shown on the summary and switches memory off. OpenAI notes it may keep a log of deleted saved memories for up to 30 days for safety and debugging. To collect memory again later, switch Enable memory back on in Settings, Personalization.
Can I turn ChatGPT Memory off completely?
Yes. In Settings, Personalization, switch Enable memory off; as of September 2026 that is the only toggle, and it replaces the separate saved memories and reference chat history switches from 2025. Turning it off does not delete existing data, so also use Delete and turn off memory on the summary page, and check the saved memories link for older entries. For a one-off conversation you want kept out of memory entirely, start a Temporary Chat.
Does ChatGPT Memory train OpenAI's models?
Memory entries are stored against your account and used to personalize replies. Whether they train future models depends on your data controls setting in Settings > Data controls > Improve the model for everyone. Turning that toggle off keeps your conversations and memories out of model training. Memory and training are independent settings, so you can keep one on and the other off.
Why does ChatGPT keep forgetting things I told it?
ChatGPT keeps what its own process judges useful, and since the Dreaming update that judgement runs in the background after a conversation ends rather than at the moment you say something. A casual mention may not become a saved memory row, and a detail can still be missing from the profile weeks later. To make sure a fact is kept, start the message with an explicit instruction like "Remember that..." or "Save this to memory: ..." and watch for the Memory updated indicator. If both memory controls are off, nothing is saved at all.
What is the difference between ChatGPT Memory and Custom instructions?
Custom instructions is a single static text box you write yourself, and it applies to every new chat. Memory is written by ChatGPT: the saved memories you ask for, plus a profile that a background process synthesises from your past chats and revises over time. You change custom instructions by rewriting the box; you change memory by correcting or deleting what ChatGPT holds. Custom instructions cover your stable identity. Memory covers everything ChatGPT has learned about you since.
Conclusion
Memory turns ChatGPT from a stateless chat into a tool that gets better the more you use it, as long as you keep the saved list curated. Open Settings, Personalization, and read the Memory summary every few weeks. Correct details that have drifted out of date through the Ask or update box. Use Delete and turn off memory when you start a new project or hand the account to a new role. Turn the Memory toggle off when you want a privacy-sensitive session, and remember that the data-training toggle is a separate switch. To search across the conversations Memory was built from, save the prompts that produced your best memories, and organize memory-heavy projects into folders, install AI Toolbox for Chrome: free plan covers 2 folders, 2 pins, 2 saved prompts, and full-text search with up to 5 results per query. Premium ($9.99 per month) or Premium Lifetime ($99 one-time) unlocks unlimited everything plus bulk export.
