ChatGPT memory: what it keeps about you, and how to see it
ChatGPT now carries things from one chat to the next. Some of it you asked it to remember; most of it, it decided on its own. Here is where it lives and what you can do about it.

Two kinds of memory
ChatGPT remembers in two ways, with a separate switch for each under Settings › Personalization › Memory.
- Saved memories — short facts it stored, either because you said "remember that…" or because it judged something worth keeping. These you can read, edit and delete.
- Chat history — it can draw on your past conversations directly. There is no list to edit here; it is on or off.
Since June 2026 ChatGPT also builds a memory summary in the background from your past chats and updates facts that go out of date. When an answer was shaped by memory, it can show which memories and chats it used, and you can correct or remove them from there.
Seeing and clearing what it knows
- Open Settings › Personalization › Memory and choose Manage memories to read every saved memory, edit one or delete it.
- Deleting a chat does not delete a memory that came from it. Remove the memory itself.
- Hiding an item so it is not mentioned again is not the same as deleting it.
- A quick check: ask ChatGPT "What do you remember about me?" and compare the answer with the list.
When you do not want it to remember
Temporary Chat starts a conversation that does not create new memories and, by default, does not use the ones it has. Since August 2026 you can choose a personalised temporary chat that reads your memories and custom instructions but still saves nothing new; the choice is made when the chat starts.
Custom instructions (Settings › Personalization) are the opposite: things you write once and want applied to every chat. They are the part of ChatGPT's picture of you that you fully control.
Where it falls short
Memory is written by the model, so it records what seemed notable in the moment — a project, a preference voiced once, a passing mood — and it does not tell you how often something was true. A preference from one frustrated evening sits next to one you have held for years.
It also stays inside ChatGPT. OpenAI offers no way to export your memories or import them elsewhere. You can download all your chats (Settings › Data controls › Export data; a link arrives by email and expires after 24 hours), but that is raw history, not a picture of you.
Where Coredence fits
Coredence reads that export — your ChatGPT conversations, along with notes, a journal or chats with Claude if you want — and consolidates them into memories about how you think and work. Each memory keeps the traces it grew from, a memory seen once waits as a draft, and you can correct one or say it is not you. It all stays in one file on your computer.
Coding assistants read it directly. For ChatGPT, Settings › Assistants › “Copy and open” copies your strongest memories at the 1,500 characters custom instructions accept and opens ChatGPT's settings; you paste. Or export the whole mind as a file and add it to a project — you choose what goes in.
