ChatGPT just got memory which allows it to remember things between chats. As you chat with ChatGPT, it will become more useful.

You can always use temporary chat if you don’t want ChatGPT to have any memory when responding.

Memory is on by default. To turn it off, go to settings, personalization, and toggle off memory.

You can also manage memories. Deactivating memories or deleting chats that created that memory doesn’t’ remove the memory. The manage option allows you to remove or modify existing memories.
Another option is you can ask chatGPT to forget something during a chat.

Practical memory applications.
