ChatGPT quietly builds a profile of you: your job, your projects, your writing preferences. Used well, memory makes every new chat start at full context. Left unchecked, it stores things you'd rather it forgot.
Here's how to see exactly what it remembers, fix what's wrong, and decide what gets saved going forward.
The fast version
- Open the memory controls. Click your profile icon, Settings, then Personalization. The Memory toggle and a Manage option live here. This is the control room for everything ChatGPT retains about you across chats.
- Review what it has stored. Tap Manage to see the full list of saved memories. Each entry is a short fact like 'User prefers concise answers' or 'User works in real estate'. Read them all the first time; most people find surprises.
- Delete what doesn't belong. Hover any memory and delete it individually. Old jobs, finished projects and wrong guesses (it sometimes infers wrong facts) should go. A lean memory file makes answers sharper, not dumber.
The thorough version
- Teach it what's missing. In any chat you can say 'remember that I run a bakery in Austin' or 'forget everything about my old project'. Plain language commands update the memory file instantly, no settings dive needed.
- Use Temporary Chat for sensitive topics. Starting a Temporary Chat (top of the screen) runs the conversation with memory off: nothing is read from your profile and nothing new gets saved. Perfect for legal, health or surprise-gift questions.
- Decide your posture per account type. If you use ChatGPT for both work and personal life, consider keeping memory on but auditing it monthly. Heavy privacy preference: turn Memory off entirely and paste context into each chat manually instead.
Common mistakes, and how to dodge them
- Assuming Temporary Chat is the default: it isn't, you must pick it each session.
- Overfeeding memory with trivia: every stored fact steers answers, so keep the list to things that genuinely shape responses.
Pro tips without the attitude
- Ask 'what do you remember about me?' in any chat for a plain-language summary, faster than the settings list.
- Reference chat history is a separate toggle from saved memories: if you want it to cite past conversations without storing profile facts, set the two toggles differently.
- Deleting a chat does not delete memories created from it, clean both.
Quick answers
Does memory work on the free plan?
Yes, memory is available on free accounts in most regions, with the same manage and delete controls.
Can ChatGPT forget everything at once?
In Settings, Personalization you can clear all saved memories in one action, and temporary chats leave no trace at all.
