What is AI memory?

The short definition

AI memory is the ability of AI assistants to remember details from your past conversations and use them in future answers. Because of it, two people typing the same prompt get different answers.

AI memory is the ability of AI assistants like ChatGPT and Gemini to remember details from your previous conversations and use them in future answers, without being asked. The model knows what you searched before, what you’ve told it about yourself, and sometimes things it only inferred.

Combined with personalization based on your history, this means two people typing the exact same prompt can get completely different answers. The answer you see is yours, not the market’s.

Why it matters for AI visibility tracking

That’s why serious AI visibility tracking runs from clean accounts with no history and no memory. Checking from your personal account measures what the AI thinks about you, not what it tells your customers.
