Summary
ChatGPT has two memory features: saved memories (which users can manage) and chat history (a newer feature that builds a profile over time without user visibility or control). The chat history feature doesn't search past conversations but maintains recent chat history and learns user preferences, though the implementation details are not publicly documented, and users cannot inspect or modify what the system learns about them unless they use prompt hacking (manipulating the AI's instructions to reveal hidden information).
