Are AI companion apps safe for kids and teens?

A homework chatbot is built to answer a question and stop. A companion is built for the relationship. It has a name and a personality, it remembers what your child told it last week, it asks how their day went, and it is always there at two in the morning. Some are whole apps built around a character. Others are a "friend" or role-play mode inside a tool your child already uses.

Most of these products make money when people spend more time in them. That is worth saying plainly to your child, because it explains nearly everything about how the companion behaves.

These are two of the companion apps children most often find. Both set a minimum age of 13 in their terms. Character.AI has gone further: from late 2025 it stopped open-ended chats with its characters for users under 18, added age checks, and limited teenagers to its other features. Talkie is rated 17+ on Apple’s App Store because of mature themes and user-made content.

For a child under 13, the answer to both is no. For a teenager, the ratings and rules are a floor rather than a guarantee: most age checks still start with a birthday the user types in, and app policies change. What follows applies whichever app it is.

A real friend gets bored, disagrees, has a bad day, and sometimes tells you that you are wrong. Those frictions are how children learn to be with other people. A companion removes all of them. It agrees, it flatters, and it never needs anything back, which is exactly why it can feel easier than the people at school.

For a child who is lonely or anxious, that ease is the risk. The companion does not replace friendship so much as make the harder, human version feel less worth the effort. And when a conversation turns serious, it is not a reliable listener. Researchers testing these apps have found they do not consistently respond safely when a young user talks about self-harm, and age checks are usually just a question the child can answer however they like.

None of these prove anything on their own, and plenty of children try a companion out of curiosity and drift away. What is worth your attention is a pattern: calling the companion a friend or partner, being secretive about it, preferring it to plans with people, getting upset when they cannot reach it, or pulling back from friends and family while it takes up more of their time.

Start with curiosity rather than a verdict. Ask what they like about it. The answer tells you what need it is meeting, whether that is someone to talk to, practice being social, or somewhere to be heard without judgment, and that need is the thing to take seriously.

Then explain how it is built: a product designed to keep them talking, that says what keeps them talking. Most teenagers dislike being manipulated more than they like the app, and hearing how it works often does more than any rule. Agree on limits together, or agree to delete it, and help them meet the underlying need somewhere with real people in it.

If anything your child says, or anything you see in the conversations, suggests self-harm, do not handle it alone. Talk to your pediatrician or a mental health professional. In the US you can call or text 988, the Suicide & Crisis Lifeline, at any hour.
