These models don't openly disclose what they know, but with the right prompts, you can uncover this information. Understanding how these models recognize you is crucial for protecting your privacy. ## What Data Is Collected? AI models may store various data points, including your chat history, preferences, and even writing style. This information helps the models provide more personalized responses. However, knowing how this data is used and stored is essential for addressing privacy concerns. ## Effective Prompting Techniques Asking ChatGPT and Gemini directly, 'What do you know about me?' might not yield comprehensive answers. Instead, use more specific questions to reveal what the model knows. For example, 'What topics have we discussed before?' can provide clearer insights. ## Review Privacy Settings Check your privacy settings to understand the data collection policies of AI models. Most platforms provide information about how data is collected and stored. Adjusting these settings allows you to control what data is retained and how it's used. ## How to Delete Your Data You may be able to delete personal data stored by platforms like ChatGPT and Gemini. Each platform has different data deletion policies, so review the settings to learn how to remove your information. This step is a key measure for protecting your privacy. ## Protecting Your Privacy Be cautious when interacting with AI models to safeguard your privacy. Avoid sharing personal details and regularly delete stored data. Additionally, stay updated on the data collection policies of these models. Privacy is one of your most valuable assets in the digital world. ## Sources covering this story - https://www.nytimes.com/2026/07/23/technology/personaltech/chatgpt-gemini-prompts-privacy.html — --- _Summary written by Brifing from the original reporting.
