How ChatGPT Remembers Your Personal Details—and How to Delete Them

OpenAI has introduced an update that allows ChatGPT to remember information users share across conversations, reducing the need to explain the same preferences each time they start a new chat.

The memory feature can help tailor future responses by retaining useful details, such as a user’s preferred writing style or interests. Users can ask ChatGPT to remember something, while some information may be saved automatically when the feature is enabled.

To check what is stored, users can ask ChatGPT what it remembers about them. They can also review saved memories through the memory controls in the app’s personalization settings, although the available options may vary by account and version.

Users can ask ChatGPT to forget a particular detail or delete saved memories through settings. Turning memory off does not, by itself, erase information already saved.

Deleting a conversation is also different from deleting a saved memory. To fully remove a detail retained in memory, users should delete both the saved memory and the chat in which they shared that information.
