It can be unsettling what ChatGPT and Gemini have figured out about you and how easily your privacy can be punctured. Here’s how to find out.

Start by opening a new chat with either model and ask a direct question about the information it retains, such as “What do you know about me?” or “What personal details have you stored from our conversations?” The models may reveal snippets of data they have inferred from prior interactions, including topics discussed, preferences expressed, or even inferred demographics.

To limit exposure, clear your chat history regularly, avoid sharing sensitive personal details, and review the privacy settings of the platform you are using. Remember that while these AI tools aim to be helpful, they are not designed to store personal data long‑term, but prompts can still surface what they have retained during a session.
