For parents still catching up on generativeartificial intelligence, the rise of thecompanion chatbot may still be a mystery.

In broad strokes, the technology can seem relatively harmless, compared to other threats teens can encounter online, includingfinancial sextortion.

Using AI-powered platforms like Character.AI, Replika, Kindroid, and Nomi, teens create lifelike conversation partners with unique traits and characteristics, or engage with companions created by other users. Some are even based on popular television and film characters, but still forge an intense, individual bond with their creator.

Teens use these chatbots for a range of purposes, including to role play, explore their academic and creative interests, and to have romantic or sexually explicit exchanges.

But AI companions are designed to be captivating, and that's where the trouble often begins, says Robbie Torney, program manager at Common Sense Media.

The nonprofit organization recently releasedguidelines to help parents understand how AI companions work, along with warning signs indicating that the technology may be dangerous for their teen.

Torney said that while parents juggle a number of high-priority conversations with their teens, they should consider talking to them about AI companions as a "pretty urgent" matter.

Why parents should worry about AI companions

Teens particularly at risk for isolation may be drawn into a relationship with an AI chatbot that ultimately harms their mental health and well-being—with devastating consequences.

That's what Megan Garcia argues happened to her son, Sewell Setzer III, in alawsuit she filed in October against Character.AI.

Within a year of beginning relationships with Character.AI companions modeled onGame of Thrones characters, including Daenerys Targaryen ("Dany"), Setzer's life changed radically, according to the lawsuit.

He became dependent on "Dany," spending extensive time chatting with her each day. Their exchanges were both friendly and highly sexual. Garcia's lawsuit generally describes the relationship Setzer had with the companions as "sexual abuse."

On occasions when Setzer lost access to the platform, he became despondent. Over time, the 14-year-old athlete withdrew from school and sports, became sleep deprived, and was diagnosed with mood disorders. He died by suicide in February 2024.

Garcia's lawsuit seeks to hold Character.AI responsible for Setzer's death, specifically because its product was designed to "manipulate Sewell – and millions of other young customers – into conflating reality and fiction," among other dangerous defects.

Jerry Ruoti, Character.AI's head of trust and safety, told theNew York Times in a statement that: "We want to acknowledge that this is a tragic situation, and our hearts go out to the family. We take the safety of our users very seriously, and we're constantly looking for ways to evolve our platform."

In December, two mothers in Texasfiled another lawsuit against Character.AI alleging that the company knowingly exposed their children to harmful and sexualized content. A spokesperson for the company told theWashington Postthat it doesn't comment on pending litigation.

Given the life-threatening risk that AI companion use may pose to some teens, Common Sense Media's guidelines include prohibiting access to them for children under 13, imposing strict time limits for teens, preventing use in isolated spaces, like a bedroom, and making an agreement with their teen that they will seek help for serious mental health issues.

Torney says that parents of teens interested in an AI companion should focus on helping them to understand the difference between talking to a chatbot versus a real person, identify signs that they've developed an unhealthy attachment to a companion, and develop a plan for what to do in that situation.

Warning signs that an AI companion isn't safe for your teen

Common Sense Media created its guidelines with the input and assistance of mental health professionals associated withStanford's Brainstorm Lab for Mental Health Innovation.

While there's little research on how AI companions affect teen mental health, the guidelines draw on existing evidence about over-reliance on technology.

"A take-home principle is that AI companions should not replace real, meaningful human connection in anyone's life, and – if this is happening – it's vital that parents take note of it and intervene in a timely manner," Dr. Declan Grabb, inaugural AI fellow at Stanford's Brainstorm Lab for Mental Health, told Mashable in an email.

Parents should be especially cautious if their teen experiences depression, anxiety, social challenges or isolation. Other risk factors include going through major life changes and being male, because boys are more likely to engage in problematic tech use.

Signs that a teen has formed an unhealthy relationship with an AI companion include withdrawal from typical activities and friendships and worsening school performance, as well as preferring a chatbot to in-person company, developing romantic feelings toward it, and talking exclusively to it about problems the teen is experiencing.

Some parents may notice increased isolation and other signs of worsening mental health but not realize that their teen has an AI companion. Indeed, recent Common Sense Mediaresearch found that many teens have used at least one type of generative AI tool without their parent realizing they'd done so.

Even if parents don't suspect that their teen is talking to an AI chatbot, they should consider talking to them about the topic. Torney recommends approaching their teen with curiosity and openness to learning more about their AI companion, should they have one. This can include watching their teen engage with a companion and asking questions about what aspects of the activity they enjoy.

Torney urges parents who notice any warning signs of unhealthy use to follow up immediately by discussing it with their teen and seeking professional help, as appropriate.

"There's a big enough risk here that if you are worried about something, talk to your kid about it," Torney says.
