To turn off ChatGPT memory, open Settings, select Personalization, then select Memory and switch off the Memory controls shown for your account, according to OpenAI’s Memory in ChatGPT help article.
As of November 11, 2026, the controls you see can include Memory, Reference saved memories and Reference chat history, and they vary by plan, region, platform and workspace. Turning off Reference saved memories also turns off Reference chat history. Turning off Reference chat history schedules information remembered from past chats for deletion within 30 days, but it does not delete your saved memories or the chats themselves.
To erase what ChatGPT already remembers, use Delete and turn off memory in the memory summary menu, or delete individual saved memories. For a single conversation, start a Temporary Chat and choose Unpersonalized; temporary chats do not create or update memories. In Business or Enterprise workspaces, an admin may control these settings.
