ChatGPT may know more about you than you can actually realise: How AI memory raises questions about privacy | Study

ChatGPT’s memory feature can retain details from past conversations, including personal information and psychological insights, a study of 2,050 memory entries from 80 users found. The findings raise questions about consent, transparency and how much control users have over what AI remembers.

ChatGPT may retain more about its users than they consciously choose to share or ask it to remember, raising questions about privacy, consent and the growing role of artificial intelligence in storing personal context.

A study titled The Algorithmic Self-Portrait: Deconstructing Memory in ChatGPT examined 2,050 memory entries donated by 80 users. Researchers analysed who initiated the creation of these memories, what information they contained and whether the entries reflected details users had shared in their conversations.

The findings suggest that ChatGPT’s memory feature relies heavily on the system’s own decisions about what information to retain. However, the researchers cautioned that the results reflect their dataset, which was relatively small and comprised volunteers who agreed to share their data.

ChatGPT creates most memories without explicit requests

Around 96% of the memory entries analysed in the study were created by ChatGPT without users explicitly asking the chatbot to remember the information. Only about 4% followed direct requests from users.

This distinction matters as AI assistants increasingly use information from previous interactions to make responses more relevant and personalised. Details shared while seeking help with work, relationships or everyday decisions may remain available beyond the conversation in which they were disclosed.

The study found that approximately 84% of the entries could be traced directly to something users had said. This suggests that the system was largely retaining information drawn from conversations, rather than generating entirely new details about individuals.
