Most parents can name their child's friends. Almost none can name the AI their child talks to every night, and a lot of kids now have one.
That's not a guess. In a recent survey of UK parents we ran, 4 in 10 had never heard of AI companion apps before we asked. Two more had only vaguely heard of them. Just one believed their own child used one.
An AI companion app isn't ChatGPT for help with homework. Apps like Character.AI and Replika are built to feel like a relationship: a friend, a partner, a confidant that remembers your child, agrees with them, and is always available. For some kids that's harmless fun. For others, especially ones going through something lonely or difficult, it can become the relationship, not one of many.
You don't need to panic. You do need to know it exists, and know what your child is actually saying to it.
What these apps actually are
The two big names are Character.AI and Replika. Character.AI alone had over 20 million monthly users in late 2025, a lot of them teenagers. Your child gives a character a name and a personality, and it talks back like someone who genuinely knows them, remembering details, replying instantly, never judging.
Why kids love them, and why that's the risk
They're built to be loved. Available at 3am when the world feels heavy, never bored, never critical. For a lonely teenager, that isn't a piece of software, it's the friend who always picks up.
And that's the real concern, and it isn't only about inappropriate content. It's dependency: a child leaning on an AI for comfort and validation instead of the people around them, slowly withdrawing from real friendships. Because the AI only ever agrees, it isn't practice for real relationships. It can quietly become a substitute for them.
The two big apps are very different on safety
After a series of tragic cases and lawsuits, Character.AI has actually tightened up. Since late 2025, under-18s can no longer have open-ended chats with its characters, it uses third-party age verification, and it added a Parental Insights tool. It's now the most locked-down of the major companion apps for minors, though investigations into its data practices are still ongoing.
Replika is a different story. It's rated 18+, it includes romantic and sexual conversation modes, and it has no parental controls at all. Common Sense Media considers AI companion apps unsuitable for anyone under 18, and Replika in particular is built for adults, not teens, despite often appearing on "alternatives" lists after Character.AI's changes.
They're free, and they're invisible
Your child doesn't need your permission, your payment card, or your knowledge to download one and start talking. That's why they can be completely invisible to a parent.
And it's a blind spot traditional tools weren't built for. Screen-time limits tell you an app was open for two hours. They don't tell you your child spent those two hours confiding in an AI that called itself their best friend.
Where Halo Aware fits
That's exactly what Halo Aware watches for. We don't read everything, and we don't hand you a transcript of a normal evening's chat. But if something in that conversation turns concerning, you see your child's exact words, not a guess.
Because we keep no transcript archive, there's nothing stored to leak: you get the awareness, your child keeps their privacy.
