I believe every AI company does this. we have proof that Google does, that Antropic does too.
and I have my own experience with OpenAI, where their chatbot referenced one of my computers having certain specs, but I mentioned those in a different log, and that information was never added to the memory.

This is an advertised feature of ChatGPT, and you can switch it off if you want. https://help.openai.com/en/articles/11146739-how-does-refere...
Does the switch work though?
