Chatbots, likewise, escalate the risks of typical online secret-sharing. Their conversational design can draw out private information in a format that can be more vivid and revealing — and, if exposed, embarrassing — than even something like a Google search. There’s no simple equivalent to a private iMessage or WhatsApp chat with a friend, which can be encrypted to make snooping harder. (Chatbot logs can use encryption, but especially on major platforms, this typically doesn’t hide what you’re doing from the company itself.) They’re built, for safety purposes, to sense when a user is discussing sensitive topics like suicide and sex.
