Here's how to delete one ChatGPT chat, or your whole history. Deleting is permanent, so start with one check. First, decide if you need a copy.
OpenAI says you can't restore a deleted chat, even through OpenAI Support. If you might want it later, export your data or save the chat first. To delete one chat, open your chat history.
Select the three-dot menu beside the chat. Select Delete, then confirm. To delete everything, open Settings, then Data controls.
Select Delete all chats. Read the message, then continue. This can affect chats in your current account or workspace, including projects.
It can't be undone. ChatGPT removes the chat from your view right away. OpenAI schedules it for permanent removal within 30 days.
Some chats are kept longer, for security or legal reasons. Deleting a chat doesn't delete files you saved on their own. Delete those separately.
A saved memory can also stay. Check Settings, then Personalization, then Memory. If you use Kortex, a chat you delete on ChatGPT stays in your Kortex Library on your computer.
To remove it there too, open its menu and choose Delete from Library, then confirm. Undo brings it back right after. Save a copy first.
Then delete.
