Settings → Personalization → Memory → Manage. Delete entries one at a time, or clear the lot. That is the whole answer. The rest of this page covers the parts that trip people up — the difference between memory and chat history, why deleted memories come back, and the one thing worth doing first.
On mobile the path is the same, under the profile menu. If you do not see a Memory section at all, memory may be turned off for your account or unavailable in your region.
Most people arrive here because one specific memory is wrong or embarrassing, and then wipe everything because the big button is easier to find. That is usually a mistake. The useful entries — how you like answers structured, what you do for a living, the things that make responses feel less generic — go out with the bad one, and you will not notice until a week later when replies feel flat.
Delete the offending entry. Leave the rest.
They are two different things in two different settings panels, and conflating them is the most common confusion here.
Clearing memory leaves your conversations intact. Deleting your conversations does not clear your memory.
Because ChatGPT writes new memories from what you say. Delete a fact, talk about the same subject next week, and it can be saved again — it has no record that you removed it on purpose.
Two fixes. Say it plainly in the conversation ("do not remember anything about this"), or turn memory off entirely under Personalization so nothing new is written at all.
One thing before you clear it
There is no undo, no trash, and no export. Once it is gone it is gone. Take thirty seconds to copy the list into a note first — if it turns out you wanted one of those entries back, that copy is the only way you will get it. If you would rather keep a proper copy, here is how to back up ChatGPT.
