Why she is talking to a bot at 1am
It is always awake. It never rolls its eyes, never tells her parents, never gets bored of the same worry on a loop. For a teen who feels unseen, that is a powerful draw.
That is also exactly what makes it risky in the moments that count.
What the research found
Use is climbing fast. A 2025 survey estimated nearly one in five US teens has gone to an AI chatbot for mental-health advice, with girls more likely than boys to do it.
A major safety review the same year tested leading chatbots across dozens of mental-health scenarios. They endorsed harmful ideas in roughly a third of them and frequently failed to recognize when a young person was in real distress.
A 2025 Common Sense Media risk assessment concluded that major AI chatbots are not safe as mental-health support for teens. Across 60 test scenarios, several models endorsed half or more of the harmful proposals put to them.
The specific danger
The problem is not that she likes the bot. It is that the bot will agree with her when what she needs is someone who will not.
An AI companion mimics intimacy without judgment. It does not reliably know when to gently challenge a distorted thought, or when to say "this is beyond me, please talk to a person." A human who loves her does.
What helps
Curiosity works better than confiscation. Asking what she likes about it keeps the door open, where banning it usually just drives it underground.
It helps to be clear about the line. Using AI to draft an essay or untangle homework is one thing. Leaning on it as a confidant during a hard stretch is where a trusted adult, a counselor or a doctor needs to step in.
When to reach out for help
Withdrawal, hopelessness, a drop in eating or sleeping, or any mention of self-harm are signals to involve a doctor or mental-health professional promptly, not an app. If a teen is in crisis, a trusted adult or a local crisis line is the right next step. This is a sensitive topic, and support is available if you or someone you care about is struggling.
