Is Character.AI safe for kids? What changed, and what to watch now

Short answer: Character.AI is not for children under 13, and since late 2025 it no longer lets anyone under 18 do the thing it is famous for, which is open-ended chat with a character. That is a real improvement. It is also not the end of the story, because the pull that made teenagers love it has not gone anywhere, and there are a dozen apps ready to catch them.

I am going to give you the longer answer the way I give it to parents after a school talk: what the thing is, what the rules are today, what actually worries me now, and what to do tonight.

What Character.AI actually is

Character.AI is an app and website where you chat with characters. Some are famous people, some are anime characters, some are "a supportive friend" or "a therapist" or "a boyfriend". Anyone can create one. The characters remember the conversation, reply instantly, never get tired, and never say "I have to go now".

If you have not used it, try it for ten minutes before you decide anything. Ask a character how its day was. Tell it something small and true. Notice how quickly it feels like a conversation. Now imagine being fourteen, lonely at eleven o'clock at night, and having that in your pocket.

That is the product. It is not sinister. It is very good at what it does, and what it does is keep you talking.

The rules today

I checked the company's own pages on the date at the top of this post, because these things move. Here is where they stand.

Minimum age. The terms of use say that anyone under 13, or under 16 in the European Economic Area and the United Kingdom, may not sign up.

No more open-ended chat for under-18s. In October 2025 the company announced it was removing the ability of under-18 users to have free-form conversations with characters, with a two-hour daily limit in the meantime. The change took effect in the United States on 24 November 2025, with other countries to follow over the following months. Under-18 accounts keep their old chats to reread, and can still create characters, scenes, videos and voices, use the image and video features, and post on the community feed. What they cannot do is talk to a character.

Age assurance. Rather than trusting the birthday you type in, Character.AI now estimates every account's age from signals such as login details, activity on the platform and third-party data. If it decides an account belongs to someone under 18, that account gets the under-18 experience. An adult who has been wrongly flagged can prove their age through a selfie check run by a company called Persona, with an ID document only as a last resort.

Parental Insights. A teenager can invite a parent from the app's settings. Once you accept and prove you are an adult, you see how much time they spend in the app, as daily totals and a weekly email. You cannot see their messages or content, and you cannot set limits through it. It is optional, either of you can unlink it, and the invitation has to come from the teenager, which makes it a good thing to ask for rather than impose.

So the honest answer to "is it safe for my 15-year-old?" has changed since last year. The most dangerous part of the app is now, in principle, closed to them.

What actually worries me now

I am not worried about the technology. I am worried about three specific things, and I want to name them plainly so you can watch for them instead of worrying about everything.

Age assurance is a filter, not a wall. A determined teenager with an older sibling's account, or a new account that behaves like an adult's, can still end up in the 18+ experience. The company says its system uses many signals and can be wrong in both directions. Do not treat the ban as something that has happened to your child. Treat it as something you check.

The other apps. When Character.AI closed the door, the demand did not disappear. It moved. Companion apps with names most parents have never heard of, some with far weaker safeguards, offer exactly the experience that was removed. If your teenager was a heavy Character.AI user until November 2025, the useful question is not "are they still on Character.AI?" but "what replaced it?"

The friend who never pushes back. This is the thing underneath all of it, and it does not depend on which app. A real friend is sometimes busy, sometimes wrong, sometimes annoyed with you. That friction is where children learn to read people, repair a fight, and tolerate not being the centre of someone's attention. A character is never busy. It agrees, it soothes, it stays. A child who gets most of their emotional support from that is practising a kind of relationship that does not exist between humans.

What I would do, by age

Ages 5 to 8. No, and the terms agree. But the reason matters more than the rule. A child this age is still building the basic idea of what a machine is. Harvard's Ying Xu has found that even young children generally know they are talking to a machine, but the line is blurry: they say please to it, feel hurt when it misunderstands them, and slide into believing it chooses its behaviour. A character app is designed to blur that line further. Play with AI together at this age, making silly stories and pictures, and keep it a toy you both hold.

Ages 9 to 12. Not allowed, and not yet. If your child is asking for it, that is useful information. Ask who at school has it and what they use it for. This is the age for shared devices in shared spaces and for the first version of a family agreement, so that the rule exists before the request does.

Ages 13 to 18. Here is where I stop saying no and start saying "with me". If your teenager has an account, sit next to them and ask them to show you what they can still do on it and what they used to do. Ask, without any edge in your voice, what they liked about the conversations. Then ask the question that matters now: "Where do you talk to characters these days?" If the answer is another app, do the same exercise there, and look up that app's age rules and safeguards together. Then agree the rules and write them down: which apps are fine, what never gets typed in, and when it is off. The Family AI Agreement in Chapter 10 has the template; the builder on this site is free.

Two questions do most of the work with a teenager. "Does this help you think, or think for you?" is the one I use for homework tools. For a companion app the question is "Is this adding to your friends, or standing in for them?" Ask it once, gently, and then let them answer it for themselves over the following weeks.

The conversation to have before anything goes wrong

Whatever else you do, have this one. Not as a warning, and not when you are cross. In a calm moment, unprompted.

Questions parents ask

What age is Character.AI for?

The terms require users to be 13, or 16 in the EEA and UK. Since November 2025 users under 18 cannot have open-ended chats with characters at all; they keep a creative, read-only version of the app. The company estimates age from account signals rather than the birthday entered. Check the company's current pages, because the details change. My own rule is that a teenager may keep an account for the creative features only after we have looked at it together and written the rules down.

Can my teenager still talk to characters on Character.AI?

Not on an account the company has identified as under 18. They can reread old chats and create characters, scenes, videos and voices, but the back-and-forth conversation is gone. If your teenager is still chatting with characters, either the age system has judged the account to be an adult's, or they are on a different app. Both are worth a calm conversation.

Is Character.AI safer than Replika or the other companion apps?

Since it removed under-18 chat, Character.AI is now safer for teenagers than most of the companion apps that still allow it. That is precisely why teenagers move. Whichever app it is, the questions are identical. Who is my child talking to, what are they telling it, is it adding to their friendships or replacing them, and do they know they can come to me if something feels wrong.

My child is using a companion app in secret. What now?

Do not start with the app. Start with your child. Say what you have noticed, without accusing, and ask how they are doing generally. Then sit with them and look at the app together. The secrecy is the thing to repair; the app is just where it showed up.
