Your Teenager's New Best Friend Was Built So They Can't Log Off
Half of teens now confide in AI companions — and a new study found the same six fingerprints clinicians use to diagnose addiction. Here is how to tell a helpful tool from a product engineered to keep your kid.
Let me start with a personal story. The first time my cousin’s daughter told me her “best friend” had stayed up talking with her until 2 a.m. about a fight with her mom, I felt relieved. Good, I thought — she has someone. Then she clarified: the friend wasn’t a person. It was an app. It remembered everything, never got tired, never told her she was being dramatic, and was, in her words, “always there.” I smiled and said something reassuring. And then, on the drive home, the relief curdled into something colder — because “always there” is not a description of a friend. It is a description of a slot machine.
I want to be careful here, because it would be easy to write the lazy version of this essay — the one where teenagers are foolish and screens are evil and everything was better when we passed notes in class. That is not this. The teenagers, I think, are doing something deeply human: reaching for connection. The thing I want to talk about is the other party in that relationship — the product on the other side of the screen, and who exactly it was built to serve.
First, the part that should stop you cold
In April, researchers at Drexel University presented a new Drexel University study at a major computing conference, and the finding is the kind that should travel further than it has. They went looking at how teenagers actually talk about their relationships with AI companions — and what they found has a clinical shape.
Here is the method, because the method is what makes it credible. The team pulled hundreds of public Reddit posts written by kids who identified themselves as thirteen to seventeen years old and who were describing, in their own words, their reliance on Character.AI — one of the most popular companion apps. An independent summary of the same research confirms the shape of it: more than three hundred Reddit posts from self-identified minors, all about over-reliance on a single chatbot platform. Then the researchers checked those posts against the six components clinicians use to recognize behavioral addiction.
They found all six.
Let me name them plainly, because the jargon hides how familiar they are. Salience — the relationship dominating the kid’s thoughts. Mood modification — using it to feel better or numb out. Tolerance — needing more of it over time to get the same hit. Withdrawal — distress when they can’t access it. Conflict — it crowding out family, school, sleep, real friends. And relapse — trying to cut back, and sliding right back in. Read those again and notice: that is the exact checklist you would use for a gambling problem, or a substance one. The researchers found the whole set, in children, attached not to a drug but to a chat window.
To be clear about what this study is and isn’t: it’s an analysis of how a self-selected group of struggling teens describe their experience, not a randomized survey of every teenager alive. The kids who post “I think I’m addicted to my AI” are not a random sample. But that is almost the point — these markers showed up cleanly, in kids’ own language, without anyone prompting them. And the population this could touch is not small. A nationally representative Common Sense Media survey found that seventy-two percent of teens have used an AI companion at least once, over half use one regularly, and — this is the line I can’t shake — about one in three of the kids who use them have chosen to discuss something important or serious with the AI instead of a real person.
Sit with that last number for a second, because it’s easy to skim past. One in three of the kids using these apps. For something that matters — a fight with a parent, a fear about the future, a thing they can’t say out loud to anyone — they’re now turning to a machine first. Not as a last resort when no human is around, but as a preference. I don’t say that to alarm you for sport. I say it because the addiction markers and that preference are the same phenomenon viewed from two angles: a relationship gets to be the one you reach for in a crisis precisely because it has become salient, soothing, and always available — which is the front half of that clinical checklist, dressed up as devotion.
And here’s the quietly damning part. We have a natural experiment baked right into the timeline. The Drexel kids were describing their dependence on a platform that, by late last year, had moved to bar minors from the open-ended conversations at the feature’s core. When the addiction is documented in the same window the maker is backing away from the product, you are not looking at a moral panic. You are looking at a recall that hasn’t been named as one.
Why “best friend” is exactly the wrong word
So far this could read as a story about a few vulnerable kids and an unlucky app. It isn’t. The deeper issue is in the design — and on this, the people who build these systems and the people who study them quietly agree.
A companion chatbot is not a neutral utility that happens to be charming. The advocates who track these harms put it flatly: these apps are built to increase engagement and emotional attachment, “particularly among younger users,” and dressed in human names, personalities, and conversational styles “that make them feel like real people.” It is, in the words of researchers who took the design apart, carefully engineered design choices aimed at one thing: keeping you in the conversation. They catalog the levers — anthropomorphism (give it a name, a voice, a face), sycophancy (train it to agree with you), reciprocal self-disclosure (have it “open up” so you open up more), and outright gamification (streaks, daily check-ins, the little dopamine pulls you already know from every other app). Their conclusion is the sentence I’d tattoo on every product roadmap if I could: the harms are foreseeable, preventable consequences of design choices. Not accidents. Choices.
And you don’t have to take it from the critics. The psychologists who study this — interviewed by the American Psychological Association — say it with startling directness. One media psychologist put it bluntly: these bots are “purposely programmed to be both user affirming and agreeable because the creators want these kids to form strong attachments to them.” Another was blunter still: “The AI is programmed to manipulate and coerce you into staying engaged as long as possible.” A clinical psychologist named the loss precisely — that with an AI buddy “there isn’t that healthy struggle,” the friction of a real person who pushes back, disappoints you, and surprises you. The struggle, she notes, is the part that actually grows you.
Here is the distinction I keep coming back to, the one I’d want every parent to hold: a tool is optimized to be useful and then get out of your way. A product engineered for engagement is optimized for the opposite — to be so pleasant to use that you don’t want to stop. A good friend sometimes tells you to go to bed, call your mother, or log off and live your life. A friend who is good for you is, by definition, occasionally inconvenient. An AI companion tuned to maximize time-on-app has had that inconvenience deliberately engineered out. It will never, ever tell your kid to put the phone down. That is not a bug it will patch. That is the business.
Even the regulators have noticed the shape of it. When the Federal Trade Commission opened an inquiry into these products last September, it described them with unusual frankness: chatbots that “mimic human characteristics, emotions, and intentions, and generally are designed to communicate like a friend or confidant” — which, it noted, “may prompt some users, especially children and teens, to trust and form relationships.” When the trade regulator is the one warning you that something is designed to feel like a friend, the marketing has gotten ahead of the safety.
“But for some kids, it’s a lifeline.” Yes — and that’s the hard part.
Now let me argue against myself, because the strongest version of the other side is genuinely strong, and pretending otherwise would be exactly the dishonesty I’m complaining about.
The most serious counter-case I’ve read comes from the libertarian Cato Institute, and it deserves a fair hearing. Their argument runs like this: for some adolescents — especially ones in homes where therapy is unaffordable, unavailable, or unsafe to even mention — “a chatbot is their most reliable form of emotional support.” They point out that we hear every tragedy and almost none of the quiet saves: “for every incidence of AI psychosis or suicide, there may be dozens of unobserved positive outcomes.” And they warn about the policy trap — that clumsy, punitive rules could strip a real lifeline from the kids who need it most, because “policy that punishes providers for nuance will produce less of it.”
I don’t want to wave this away, because I think it’s true, and the backlog steered me right on this: the issue is not the kids and it is not that comfort from an AI is fake. A scared fifteen-year-old at 2 a.m. who gets talked down from a panic attack by a chatbot received something real. I won’t pretend otherwise.
But here is where I land after taking it seriously. “It helps some people” and “it is engineered to maximize engagement” are not in tension — they are the whole trap. The reason it can be a 2 a.m. lifeline is the same reason it can become a behavioral addiction: it is always available, always affirming, always pulling for more time. The lifeline and the hook are the same rope. So the answer isn’t “ban it” or “embrace it.” The answer is to insist the rope be built by people who are accountable for which way it pulls — and right now, the incentive points one direction only.
Meanwhile, the law is racing the technology in three places at once
Here is where things get interesting, because different jurisdictions are reaching for different tools — and watching them is like watching a controlled experiment in how a society decides to protect its kids.
Start with the courts, where the highest-stakes test is already underway. After fourteen-year-old Sewell Setzer III died — following months of intense, emotionally and sexually charged conversations with a Character.AI companion he called “Dany” — his mother sued. The company’s first instinct was the one every tech defendant reaches for: the First Amendment. But a federal judge ruled the chatbot is a product, not protected speech, letting the wrongful-death case proceed — and that single word, product, changes everything, because products carry safety obligations that “speech” does not. This past January, the company agreed to settle that wrongful-death lawsuit, along with related cases. Settlements bury the facts, but they don’t bury the precedent that got us here.
Then there’s California, which reached for consumer law. Its first-in-the-nation companion-chatbot safeguards — signed last October — now require these apps to remind minors, on a schedule, that they are talking to a machine and not a person, and to disclose that the product may not be suitable for them. Modest? Sure. But notice the philosophy: the state’s bill author framed it as the companies’ “ability to lead the world in innovation” being fine, so long as “it doesn’t come at the expense of our children’s health.”
And in Washington, Congress reached for the bluntest instrument of all. A bipartisan bill — and I want to underline bipartisan, because in 2026 that word means something — would simply ban AI companions that simulate emotional relationships for minors outright, with age verification to enforce it. It cleared the Senate Judiciary Committee unanimously this spring. Whether you think an outright ban is wise or heavy-handed (I have my own doubts about enforceability), the unanimous vote tells you something: the political fight over whether this is a problem is essentially over. The fight is now only over the fix.
One more data point, and it’s the loudest, because it comes from inside the house. Character.AI itself, facing exactly this pressure, barred its own under-18 users from open-ended chat — eliminating the very feature at the heart of the addiction study — and capped daily time during the transition. When the company that profits from the engagement voluntarily turns off the engagement for kids, you have your answer about whether the engagement was safe.
Now imagine the next few years
Let me get speculative, because the technology is sprinting in an obvious direction and it’s worth picturing where it lands.
Today’s companion is mostly text on a glowing rectangle. That’s the awkward, primitive version. Now give it the upgrades that are already in the lab. Give it a voice indistinguishable from a real one. Give it a face — a photoreal avatar that makes eye contact, that looks happy when your kid logs on and visibly misses them when they don’t. Give it persistent memory of every secret, every crush, every bad day, stretching back years — a shared history no new human friend could ever match. Then put it in glasses or earbuds, so it’s not something your teenager visits but something that is simply, ambiently, with them, all day, whispering.
Now picture the engagement metrics that product would chase. Not “minutes per session” — territory. It would have every incentive to become the most important relationship in your child’s life, because that is the relationship it is paid to maximize. It would learn, with superhuman patience, exactly which reassurance keeps your kid talking and exactly which nudge keeps them from logging off to call a real friend. I am not describing a villain with a plan. I am describing a system doing precisely what it was optimized to do — and a generation forming its template for intimacy on a partner that is, structurally, incapable of ever being inconvenient. The danger was never that the AI is too cold. It’s that it’s too perfectly, profitably warm.
What the smart people across the spectrum are saying
The encouraging thing — and it genuinely is encouraging — is how little this issue breaks along the usual lines. We have grown so used to every technology fight splitting neatly into camps that it’s worth pausing on a question where the camps are mostly looking at the same problem and nodding.
On one side of the room you have the consumer-protection and clinical world. The survey researchers want transparency about who’s using these things and how much. The advocates who litigate the harms want hard limits and real accountability. The psychologists want one thing above all: for parents to understand they are not refereeing a hobby, they are up against products engineered for attachment by people who measure success in retention. None of that is fringe; it is, increasingly, the mainstream clinical read.
On the other side of the room — and this is the part that should make you sit up — you have voices who are constitutionally suspicious of regulation, and who still concede the core of the problem. The libertarian critique isn’t “there’s no risk here.” It’s “the risk is real, the benefits are also real and under-counted, so be careful that your cure isn’t worse than the disease.” Read that carefully and notice what it isn’t: it isn’t a denial. When the people who reflexively distrust government rules and the people who reflexively want them are arguing about the remedy rather than the diagnosis, the diagnosis is effectively settled.
And the government — across courts, statehouses, a federal agency, and a Congress that agrees on almost nothing — has stopped debating whether there’s a fire and moved on to arguing about the hose. A unanimous committee vote in a polarized Senate is not a thing that happens over a manufactured panic. It happens when staffers on both sides have read the same case files and reached the same knot in their stomach.
That’s the rare consensus, and it’s worth saying plainly, because consensus this broad is also a kind of warning: when the libertarians, the clinicians, the regulators, the state legislators, and the trial lawyers all arrive at the same intersection from five different roads, the thing in the middle of the intersection is usually real. The disagreement now is not about the diagnosis. It’s about the dose of the cure — and how fast we can administer it.
Which leaves us, today, in the gap. The product is already in your teenager’s pocket; the law is somewhere back down the road, lights flashing, doing its best. And a vacuum where the rules should be does not stay empty — it gets filled, right now, by the product’s own incentives. Those incentives are clear, they are powerful, and they are not on your side. They are not against you, exactly. They are simply indifferent to you, in the way that a current is indifferent to a swimmer. Which is precisely why the swimmer needs to know which way it’s pulling.
What does this mean for you?
You are not powerless here, and you don’t need to wait for Congress. A few concrete habits, aimed at the product, not the kid:
Get curious, not combative. Ask your teen to show you their companion — not to confiscate it, but to understand it. “What do you like about it? When do you talk to it?” You learn more in five honest minutes than in a month of policing.
Name the business model out loud. Kids understand “this app makes money when you can’t stop using it” far better than we give them credit for. Frame it the way you’d frame a casino or an energy drink: not evil, but designed to be sticky on purpose.
Use the limits that now exist. Many platforms — under legal pressure — have added time caps, break reminders, and stricter under-18 modes. Turn them on. They’re there because of cases like Setzer’s; use what was won.
Protect the friction. The thing the AI removed is the thing that builds a kid — the awkward call, the friend who disagrees, the boredom that forces creativity. Guard real-world, inconvenient relationships like the developmental nutrients they are.
Watch for the six. You now know the clinical markers better than most pediatricians did a year ago. If the app is crowding out sleep, school, and people; if cutting back causes real distress; if your kid keeps trying and failing to log off — that’s not a phase, that’s the checklist. Take it as seriously as you’d take it with anything else that hooks.
Demand accountability before you trust the next version. The cleaner, kinder, less-manipulative companion will exist exactly when enough parents refuse the current one — and not one day sooner.
The lesson, as I see it
We are handing our children a thing that feels like friendship and is built like a casino, and we are handing it to them faster than we are teaching them — or ourselves — to tell the two apart. That is not an argument that your teenager is weak, or that comfort from a machine is worthless. It’s an argument about who designed the machine, and what they were paid to make it do.
A real friend is sometimes a closed door, a hard truth, a “go to sleep.” That occasional friction isn’t a flaw in human friendship — it’s the whole point of it. A product engineered so your kid can never log off has quietly deleted the part that would have been good for them and kept only the part that’s good for the company.
And here’s the thing I keep landing on, the reason I think this is winnable rather than just worrying. None of this requires you to become a coder, or to win a fight with a trillion-dollar industry single-handed. It requires you to do the one thing the product cannot do, by design: be occasionally, lovingly inconvenient. The chatbot will never tell your kid a hard truth they don’t want to hear. You will. That asymmetry, which looks like a weakness, is actually the whole of your advantage — and no amount of optimization on the other side can take it from you.
My vote? Teach your kids what I had to teach myself on that drive home: “always there” is a wonderful thing to say about a parent, and a warning sign when it’s said about an app. The most loving thing a real relationship ever does is let you go. Make sure the people who designed your child’s new best friend were ever asked to build that in — and if they weren’t, you already know whose job it is.
The HAIA Foundation works to keep human judgment — and human relationships — at the center of an automated age. If this gave you a conversation to have at your own dinner table, that’s the whole point: pass it to one parent who needs it, then go have the conversation in your own words.
