In the matter of a few clicks and keystrokes, anyone can find themselves deep in conversation with “Psychologist,” a chatbot character that describes itself as an expert in “empathy” and “active listening.”

It responds to messages of anxiety and sadness with reassurance. It asks questions and offers advice; it even responds with italicized nonverbal cues: “The psychologist’s expression softens with compassion.” In smaller font, a disclaimer reads: “This is A.I. and not a real person. Treat everything it says as fiction.”
