AI privacy: What does AI know about you?

Every chat with mainstream AI leaves a record behind. Anything you type is stored and analyzed, and you’re liable to end up training their models and building a profile on yourself. Even casual prompts can reveal deeply personal details, from your work and routines to your relationships and identity.<br>AI Paper Trail is a free tool that helps you see that exposure for yourself. Upload your exported data to get a private report of exactly how much your AI knows about you — and what you can do about it.

AI data privacy concerns

A single prompt might not give away much about you. But weeks or months of them — whether it’s drafting work emails, getting advice for personal health and relationships, or just something you were too embarrassed to Google — can reveal who you are with uncomfortable accuracy.<br>Your personal data is extremely valuable. A behavioral profile based on what you ask, what you worry about, and what you’re likely to buy can be worth thousands of dollars to advertisers and data brokers. This is how AI profiling works in practice, and is exactly why Big Tech AI tools are designed to collect as much of your data as possible.<br>Here’s what most popular AI platforms, including ChatGPT, Claude, and Gemini, retain about you by default:

Conversations and responses

Uploaded files and documents

Usage patterns, such as how often you use the tool, what features you use, and how long your sessions last

Device and network data, including IP address, browser type, operating system, and approximate location

Account information, such as your name, email address, and any profile details you’ve provided

And under many platforms’ default settings, your data can be stored for extended periods or indefinitely, used to train AI models, and shared with third parties — often without your knowledge or direct consent. The question now is exactly how much your AI already knows about you.

How much does AI know about me?
