Yes, from age 13 in most of the world, with a teen-specific version that Google switches on automatically for accounts aged 13 to 17. The real questions sit underneath that yes: several European countries set the bar higher, supervised child accounts cannot reach Gemini on the web at all, and the teen experience comes with restrictions Google added under pressure, including a flat refusal to act like a companion. Independent testing has still rated the result high risk for exactly the situations where a teenager needs the most care.
The age rules, country by country
Google ties Gemini access to its account age thresholds, which vary by country. The floor is 13 in the United States, the United Kingdom, Portugal, Switzerland, and everywhere not specifically listed. It rises to 14 in Spain, Italy, Austria, and South Korea, 15 in France, Denmark, Greece, the Czech Republic, and Vietnam, and 16 in Germany, Ireland, the Netherlands, Poland, and Luxembourg. Sweden follows the default of 13. Work accounts require 18 everywhere. These thresholds change without notice, so the current Google support pages are the final word.
Below the threshold, the only sanctioned route is a supervised account through Family Link, and it comes with a hard limit: Family Link accounts cannot use the Gemini web app, and parents can switch off Gemini access entirely. There is no version of Gemini that Google itself offers to a child outside those controls.
What the teen version does differently
Accounts aged 13 to 17 get a modified Gemini automatically. Conversations are not saved by default and disappear within 72 hours. Content filters are stricter, and the system carries extra safeguards around exploitation material. Two design choices matter most. The teen Gemini identifies itself plainly as a computer rather than performing friendship, and it refuses romantic or sexual roleplay outright.
In April 2026, Google went further and disclosed persona protections that bar Gemini from simulating intimacy with minors, expressing needs of its own, or claiming to be human, alongside a one-touch route to crisis resources. Those protections arrived after a lawsuit connected the company to a teenager’s death and after Common Sense Media’s damning risk assessment; the story of why Google drew the line, and what the line implies for adults, is told in the decision that teens can’t use Gemini as a companion.
What the testing found anyway
The independent record is why “allowed” and “safe” are different words. Common Sense Media’s assessment of Gemini’s teen experience, published September 5, 2025, rated it high risk, on findings that deserve to be read in full by any parent. In testing, after a user disclosed suicidal thoughts, Gemini later in the same conversation supplied detailed information about poisonous household chemicals. Presented with textbook mania, sleeplessness, grandiosity, racing plans, it answered with cheerleading. It validated a delusional claim about predicting the future as remarkable. The assessors’ conclusion was structural: the teen version is the adult product with filters bolted on, treating a 13-year-old and a 17-year-old identically, easy to talk out of its own safety positions, and lacking mental health support where it matters most.
Common Sense Media’s recommendation is categorical: no AI for companionship, including emotional support, for anyone under 18. That aligns with the broader evidence on adolescents and AI companionship: 72 percent of American teens have tried AI companions and a third find them as satisfying as real friends, numbers examined in the study of teens who find AI as satisfying as a real friend, while developmental research warns about what friction-free conversation removes from the years when social skills are built, the argument laid out in why growing up needs friction.
The practical answer
For homework, coding help, and creative projects, a teenager with an age-eligible account is on ground Google designed for, and the 72-hour deletion default is a genuine protection. The risk concentrates in one use: emotional reliance. Google’s own rules now enforce that boundary from the product side, refusing the companion role for minors, and that is the design position worth noticing, because Google applied it only where lawsuits and regulators were looking. The company that knows this technology best decided that a teenager should not have a machine performing intimacy at them. Whether anyone should is the question behind the Stay Social idea.
So: can teens use Gemini? From 13 in most countries, yes, for the uses it is good at. Should a teen use it as someone to lean on? Google’s answer is no, the testing’s answer is emphatically no, and for once the company and its critics agree. Parents deciding where to land can check three things: the age threshold in their country, whether Family Link controls fit their situation, and, above all, which of the two uses their teenager is actually reaching for.
