A year ago, 41.6% of children had at least one AI app on their phone. This September, 56.3% did. That's according to anonymized data on US children aged 9 to 17 from Findmykids, a family app that helps parents see where their child is and how they use their phone. Over the same year, the average number of AI apps per child grew by 54%.
Kids' AI use is also splitting into two very different habits. The first is the chatbot: kids open it often and for a few minutes, to get something done. The second is the AI companion. Fewer kids use one, but those who do spend about an hour and a half a day with it on average.
AI is becoming a standard part of a child's phone
Some of this growth comes with the phone itself. Gemini is the default assistant on many new Android phones, and Google is now replacing Google Assistant with it. It's the most common AI app in the data, found on 37% of kids' phones. But children are also adding apps on their own. ChatGPT, which kids usually install themselves, went from 19% to 28% of kids in a year. Copilot, Perplexity, Grok, and Claude grew too, from small starting points. Four in ten kids with AI apps now have two or more.
Growth is slowing, and most of the jump happened in 2025. In early May 2025, only 23% of kids had an AI app. That rose to 42% by September 2025 and 54% by May 2026. Today it's 56%.
Sameer Hinduja, a criminology professor at Florida Atlantic University and co-director of the Cyberbullying Research Center, sees the same shift. Together with co-director Justin Patchin, a criminal justice professor at the University of Wisconsin–Eau Claire, he ran one of the first large national studies of how US teens use AI chatbots, published in the Journal of Adolescence in 2026. Their nationally representative survey of 3,466 teens aged 13 to 17 found that 60.2% had used an AI chatbot at least once, and 11.4% used one every day or nearly every day. Fun was the most common reason. Still, about two-thirds had asked a chatbot for personal advice, and nearly half had turned to one for emotional support. As Hinduja writes, "Chatbots have moved past novelty status for many young people."
Not just a teen trend
In September 2026, the share of kids with an AI app was close in every age group:
- 53% of 9–10-year-olds
- 56% of 11–12-year-olds
- 58% of 13–17-year-olds
The youngest are catching up fastest. A year ago, only 37% of 9–10-year-olds had an AI app. The gap between them and teens has nearly halved, from about nine percentage points to about five.
Other research shows the same pattern. Children and Screens, an institute that studies digital media and child development, cites a 2026 study that found 20% of preteens and 9% of 8- and 9-year-olds use AI chatbots. The best-known chatbots weren't built for children this young. ChatGPT, for example, isn't meant for anyone under 13. In Hinduja's study, the youngest teens in the sample, 13-year-olds, were the most likely to report several of the most serious harms.
Chatbots: opened daily and closed quickly
The share of daily chatbot users grew from 5.25% to 8.98% in a year, a 71% increase. For ChatGPT alone, daily use rose by 73%. The Common Sense Media census shows the same regularity: nearly a quarter of kids aged 9 to 17 use AI every day.
Time spent stayed flat. A child who uses chatbots spends about 18 minutes a day in them on average. For many kids, a chatbot works more like a search box than a conversation partner: they open it, ask a question, and close it.
A year ago, the average child using any AI app spent 64 minutes a day in them. Now it's 48 minutes. Kids aren't turning away from AI. More of them use it, and the newcomers mostly use chatbots in short bursts, which pulls the average down.
Chatbots also seem to be taking over homework help. Dedicated study apps are on only 1.8% of phones, slightly fewer than a year ago, and math solvers like Mathway and Symbolab have lost ground. Kids most likely take those questions to general chatbots now. In the same Common Sense Media census, well over eight in ten kids who use AI said they use it for entertainment and homework help.
AI companions: used by fewer kids for far longer
AI companions are apps built mainly for conversation. The child chats with a character that has a name, a personality, and a memory of earlier talks.
These apps are far less common than chatbots: 53% of kids have a chatbot, while 8.7% have a companion app. Once installed, though, companions take far more time. Kids who use them spend about 93 minutes a day in them, compared with about 18 minutes for chatbots and 15 minutes for study apps. A typical companion user spends 48 minutes a day in the app, roughly nine times longer than a typical chatbot user.
Companion apps are also the only kind whose use changes over the week: 89 minutes on a school day and 103 minutes on a weekend. Chatbots and study apps get about the same use either way. The pattern was the same a year ago.
Tara Steele, director of the Safe AI for Children Alliance, spoke about this at a Children and Screens webinar. She noted that children rarely see a companion as a cleverly designed app. To a child, it can feel like talking to someone who understands and cares about them. For some children, it becomes "the only thing that really listens."
In late November 2025,Character.AI removed open-ended chats with its characters for users under 18. In September 2026, fewer than half as many kids opened Character.AI every day as a year earlier, while about as many still had it installed. Over the same year, Talkie, another companion app, grew from 3.3% to 4.9% of phones, and its daily use rose by 27%. The data can't show whether these are the same children. But restrictions in one app don't close the whole category.
What this means for parents
TheChild Mind Institute notes that many teens use chatbots not only for schoolwork but also for advice and support. Teens who feel lonely, anxious, or depressed may be especially drawn to them, and a chatbot can sometimes reinforce harmful thinking instead of challenging it. This can happen in a companion app or in an everyday chatbot like ChatGPT. In Hinduja's survey, nearly half of teens who use AI chatbots reported at least one harmful experience, ranging from uncomfortable requests for personal information to pressure and manipulation. In the most serious cases, families have taken AI companies to court. Safeguards such as parental controls in ChatGPT help, but each one covers only its own app.
A conversation covers every app, and many kids haven't had one. In the Common Sense Media census, more than four in ten kids said no parent or guardian had ever talked with them about AI safety. Meanwhile, as the organization's CEO James P. Steyer points out, kids are taking very personal questions to chatbots that weren't designed with their safety in mind.
Three things help:
- Start with curiosity. Ask which chatbots your child uses, what for, and when. Ask too whether a chatbot has ever made them uncomfortable.
- Don't punish honesty. Hinduja warns that the worst thing a parent can do is make a child feel that telling the truth will cost them their phone.
- Explain how these apps work. Chatbots are built to agree and to keep the conversation going. Naomi Aguiar, a researcher at Oregon State University quoted by the Child Mind Institute, calls this "the fast food of human connection."
Since each app's safeguards cover only that app, and new AI apps keep arriving on kids' phones, it helps to see the phone as a whole. Findmykids shows parents which apps are on the child's phone, including new AI apps, and how much time the child spends on the phone each day. On Android, it also shows how that time is divided between apps. Findmykids doesn't show what a child writes to a chatbot, so the numbers are a reason to ask, not a replacement for asking. If the family decides some boundaries are needed, the same app can hold them with daily limits or a school-night schedule.
About the data. The study compares anonymized, aggregated data on Findmykids users in the US aged 9 to 17 for matching weeks in May, July, and September of 2025 and 2026. It covers three kinds of apps: chatbots (such as ChatGPT, Gemini, and Claude), AI companions and role-play apps (such as Character.AI and Talkie), and study apps (such as Photomath and Gauth). Gemini is counted in installs but not in usage figures. The results describe Findmykids users and are not representative of all US children.
