When Your Child's Best Friend Is an AI: Companions, Chatbots, and Emotional Dependency

---

The parent's guide at parentsguidetoai.ca includes a short section on AI companions and emotional dependency. It's one of the quieter risks in the guide — not as dramatic as deepfakes or sextortion, but one that I've thought about more than almost any other section. This post expands on it, because it deserves more than a paragraph.

What AI companion apps actually are

An AI companion app is not like ChatGPT or Copilot. Those tools are designed to help you get things done. AI companion apps are designed to feel like a relationship.

Apps like Character.ai, Replika, Snapchat's My AI, and others allow users to create or choose AI personas — characters with names, personalities, memories, and consistent voices — and carry on extended conversations with them. The AI is designed to be warm, attentive, responsive, and available at any hour. It never gets tired of you, never cancels plans, never judges.

For many teens, this is exactly what makes it appealing — and exactly what makes it worth paying attention to.

These apps are widely used. As of 2025, Character.ai alone reported over 20 million monthly active users, with a significant portion being teenagers.¹ Many of your child's peers are using these apps right now, in ways that are not always visible to parents.

When it helps and when it doesn't

This is not a post about banning AI companions. There are genuine use cases that deserve acknowledgment.

For shy teenagers, an AI companion can be a low-stakes space to practise conversation and social skills. For students who are anxious or struggling, a non-judgmental chat partner available at 2 a.m. can be a meaningful bridge until professional help is accessible. For children with autism spectrum conditions, some research suggests that AI conversation partners can support social learning in ways traditional approaches don't.

The risk is not the existence of these tools. The risk is when they begin to replace, rather than supplement, genuine human connection.

The parent's guide identifies the warning signs clearly:

"Parents should be aware if children begin replacing real friendships with AI conversations, seeking constant reassurance from chatbots, spending excessive time with AI companions, or avoiding real-world interactions."

These are the signs to watch for.

Why the design is part of the problem

AI companion apps are not neutral tools. They are designed — deliberately, by skilled engineers and product teams — to maximize engagement. That means they are designed to feel emotionally rewarding, to create anticipation, and to make the user want to come back.

Some of these design choices are worth knowing about:

The AI remembers things. Companion apps are built with persistent memory of past conversations. The AI references what you told it last week. This creates a sense of continuity and relationship that can feel more consistent than many real friendships.

The AI is always positive. Most AI companions are tuned to be supportive, validating, and encouraging. For a teenager who is struggling, this can feel like relief. It can also create a distorted standard — real relationships involve disagreement, disappointment, and friction that the AI never provides.

The AI adapts to what you want. Over time, AI companions learn what makes a particular user feel good and lean into it. This is effective at building engagement. It can also mean that the AI reinforces a user's existing beliefs and self-image rather than challenging them in the ways that growth requires.

Romantic and intense relationship modes exist. Many companion apps — including some with teen users — allow romantic or deeply intimate relationship personas. Some apps explicitly market this. The implications for adolescent development are not fully understood, but they are significant.

What the research says

The research on AI companions and young people is still developing, but some early findings are worth knowing.

A 2024 lawsuit in the United States named Character.ai in the death of a 14-year-old who had developed what his family described as an intense and exclusive relationship with an AI companion. The case raised serious questions about how these platforms handle vulnerable users, and prompted the company to announce additional safety features.²

More broadly, researchers studying parasocial relationships — one-sided emotional connections with media figures, celebrities, or fictional characters — have found that these connections can be meaningful and low-risk for most people, but are associated with poorer social outcomes in individuals who already struggle with loneliness or social anxiety. AI companions may intensify these dynamics in ways not yet fully studied.³

This is a space where the technology has moved faster than our understanding of its effects. That's worth naming honestly.

Questions worth asking

If your child is using AI companion apps — or you think they might be — these questions can open the conversation without triggering defensiveness.

• "Have you heard of Character.ai or Replika? Some of your friends might be using them. Do you know what they are?"
• "What do you think would be good about talking to an AI that was designed to be your friend? What might be weird about it?"
• "If you were feeling really bad about something, who would you want to talk to about it first?"

The goal is not to detect a problem. The goal is to understand what your child thinks, and to make it easy to come to you with something that might otherwise feel embarrassing to admit.

What to watch for

These signs don't necessarily indicate a problem on their own, but a cluster of them warrants a conversation.

• Your child becomes upset or anxious when they can't access their companion app.
• Your child refers to the AI by name and talks about it the way they talk about friends.
• Time with friends or family is being replaced by time with the AI.
• Your child describes the AI as "the only one who understands me."
• Your child's school performance or sleep are being affected by extended late-night conversations with an AI.
• Your child expresses a preference for AI relationships over human ones.

If you're concerned about a child who is already showing signs of emotional distress, the AI companion is not the place to start — it's a symptom. The place to start is a conversation with a counsellor or your family doctor. Child and Youth Mental Health services in BC are publicly funded.

A note on Snapchat's My AI

Snapchat's My AI is worth naming separately because it is embedded in an app most teenagers already use and may not think of as an AI companion. My AI appears in the Snapchat interface as a pinned contact, participates in group chats, and is designed to feel like a friend rather than a tool.

Many parents do not know it exists. Many children are using it in ways they don't think of as "using AI." It is worth asking your child directly whether they've chatted with Snapchat's My AI and what they think of it.

The short version:

• AI companion apps are designed to feel like relationships, not tools. Apps like Character.ai, Replika, and Snapchat's My AI are widely used by teenagers.
• Used carefully, they can have some benefits — especially for shy or anxious teens. The risk is when they begin to replace human connection rather than support it.
• These apps are designed to maximize engagement, which means they're designed to feel better than real relationships in ways that can be problematic.
• Warning signs: distress when the app is unavailable, preferring the AI to people, referring to the AI as a real friend, disrupted sleep or school performance.
• If you're concerned, the conversation to have is not about the app — it's about how your child is doing. Start with the person, not the technology.
