The short answer: Gemini is useful for homework, but Common Sense Media rates both its teen and under-13 versions high risk — essentially the adult product with filters bolted on. It can be confidently wrong, can surface content the filters miss, and shouldn't be used by under-18s for companionship or emotional support. From 13 it's manageable with Family Link supervision in place, data settings checked, and a firm "schoolwork, not feelings" rule.
What Gemini is
Google's AI assistant — an app, a website, and built into Android, Search and Workspace. For most teens, the number-one use is homework.
The real risks
- Confidently wrong answers. Like every AI chatbot, it'll state things with full conviction that are simply incorrect — risky if kids treat it as a source.
- Emotional over-reliance and mental-health blind spots. Reviewers have documented missed signs of distress; no under-18 should be using AI chatbots for emotional support.
- Inappropriate content despite filters. Google itself says the safety filters "aren't perfect", and some adult or upsetting content still gets through.
So what age is it OK?
A standard Google account is 13+, and 13–17s get a "teen experience" automatically. Under-13s can only access Gemini via a Google Account supervised through Family Link, and a parent decides whether it's on or off. We'd treat 13 as the floor, with Family Link on, data settings checked, and a clear rule about what it's for.
What we do
Decide deliberately in Family Link — open your child's profile, Controls → Gemini, and toggle Gemini Apps on or off. Don't leave the default unexamined. Check the activity settings: "Keep Activity" is already off for under-13s; review it for teen accounts. Set Screen Time or app limits in Family Link. Then the most important bit — a house rule that AI is for homework and creating, never for advice or company, and answers always get double-checked.
The bottom line: Gemini can be a useful homework tool from 13 — but only with Family Link in place and the "schoolwork, not feelings" rule made clear from day one.
