Stanford analyzed 464,687 private chats: opening up to AI friends worsens well-being

Stanford analyzed 464,687 private messages between users and AI companion apps, surveying 1,131 adult users (237 donated chat histories) and measuring their well-being.
Key finding: users who treated the AI as a friend and opened up the most felt the worst — the opposite of human relationships, where sharing builds closeness. Only 11.8% cited companionship as their main reason for using the app, yet 51% called their chatbot a friend, companion or romantic partner, and 80.3% of conversations involved seeking emotional support. Notably, heavy usage alone wasn't harmful — heavier users reported higher well-being; the damage came from a particular usage pattern.
The posting account is skeptical, arguing these are just lonely people failing to find relief in AI — it isn't really about AI at all.
