ChatGPT, Gemini, and Claude now permanently store details from conversations and use them to provide more personalized responses, according to the article. This "Memory" feature is enabled by default with major providers, and on Google it is enabled by default and must be actively turned off. The more extensively users discuss their career, family, health, or financial matters, the more information each tool collects. The article says a simple prompt can get a chatbot to list what it has stored about you, sometimes including inferences that were never explicitly stated. In the settings of every major provider, users can view, restrict, or completely disable the memory function, often found under headings such as "Personalization" or "Saved Information." For conversations about health, finances, or work-related matters, the article recommends using temporary mode. It also advises caution when sharing specific details in plain text, stating that with the right prompt, temporary chat mode, and a bit of caution, users can regain control over their own data.
