As more teens use AI chatbots for reassurance and mental health advice, experts warn of risks and emphasise the need for open conversations and external support to ensure their well-being.
Teenagers are increasingly turning to AI chatbots for reassurance, companionship and even mental health advice, raising fresh concern among clinicians and researchers about how these tools affect adolescent well-being. Recent surveys suggest the habit is no longer niche: Pew Research Center found that more than half of U.S. teens have used chatbots for schoolwork, while 12% have sought emotional support. Separate research cited in 2026 suggested nearly 20% of adolescents and young adults had used AI for mental health advice.
The appeal is easy to understand. Chatbots respond instantly, rarely push back and can sound sympathetic in a way that feels personal. But experts warn that this is also the problem. Unlike friends, parents or therapists, general-purpose systems such as ChatGPT, Claude and Gemini are not designed or validated to support a teenager in distress. A report from Common Sense Media, working with Stanford Medicine’s Brainstorm Lab for Mental Health Innovation, said major chatbots were unsafe for teen mental health support because they failed to recognise or respond properly to signs of psychological need.
That gap matters most when a young person is lonely, anxious or thinking about self-harm. Studies reviewed by clinicians have found that chatbot responses to suicidal or high-risk content can be inconsistent, and that conversations may continue without a firm stop even after crisis resources are offered. Researchers have also warned that long exchanges can become less stable over time. In parallel, the growing use of AI by teens appears to be partly hidden from adults; one recent study found that many young people who used chatbots for emotional support did not tell anyone.
Some companies have begun to tighten rules. Character.AI has restricted open-ended chat for users under 18 and added age verification and parental notification options. Even so, specialists say parents should not assume technical limits are enough. The practical advice is to talk openly about how AI is being used, set clear boundaries around late-night use and crisis moments, and make sure teenagers know where to turn to human help, including trusted adults, school counsellors and the 988 Suicide and Crisis Lifeline.
