AI chatbot for kids: which ones are safe, and which to avoid

Three types, three very different risks

Parents ask "is this AI chatbot safe for my kid?" as if safety were a property of the app. It's mostly a property of the business model. Ask what the bot is optimized for and the answer usually falls out.

Moderated tutors — safest

Khanmigo and similar school-oriented tutors are constrained on purpose: they steer toward the subject, refuse to write the assignment outright, and log activity for a parent or teacher. Narrow, a bit dull, and the right default for under-12s.

General assistants — fine with setup

ChatGPT, Claude and Gemini are adult tools with adult defaults. They're reasonable for kids roughly 10 and up once a parent owns the account and changes the settings — see our ChatGPT safety setup guide for the exact toggles.

Companion bots — avoid

Character.AI, Replika and the wave of "AI friend" apps are engagement products. The design goal is that your child comes back and keeps talking. That is a poor fit for a developing sense of what a relationship is, and it's the category behind most of the alarming headlines.

What a kid-friendly AI chatbot actually looks like

• It ends conversations cleanly instead of asking your child a question back every single turn.
• It says "I'm not sure" and points to a source rather than inventing a confident answer.
• It refuses to produce a finished assignment, and offers to explain instead.
• The parent can see what happened — history, a dashboard, or a shared account.
• It doesn't have a persona your child could mistake for a friend.

Four settings that make any chatbot safer

• Parent-owned account, so history is visible without a special feature.
• Memory off, so the bot doesn't build a profile across conversations you never see.
• Model training opt-out, so their prompts aren't training data.
• Voice mode off for under-12s — voice is what makes it feel like a person rather than a tool.

By age, briefly

Under 10: no solo chatbot at all; use AI together on your device. Ages 10–12: a moderated tutor, or a general assistant on your account with you nearby. Ages 13–15: their own linked account with rules agreed up front. Ages 16+: independence, with conversations about judgment rather than monitoring. The account-age rules behind this are covered in how old you have to be to use ChatGPT, and the minimum age for every other app is listed in AI age limits, app by app.

Side-by-side: the chatbots parents ask about most

• **Khanmigo** — type: moderated tutor. Minimum age 13 (or a parent-linked child account through Khan Academy). Refuses to write assignments; nudges with questions instead. Verdict: safest default for 8–13 with a parent account.
• **ChatGPT** — type: general assistant. Minimum age 13 with parental consent, 18 without. Will write the essay unless told not to. Verdict: fine from about 10–12 on a parent-owned account with memory and training off.
• **Claude** — type: general assistant. Minimum age 18 per terms, so use is on your account. Tends to explain rather than dump answers. Verdict: the better of the two assistants for homework explanation.
• **Gemini** — type: general assistant, wired into Google accounts and school Workspace. Teen experience exists via Family Link. Verdict: acceptable for 13+, but check what it is connected to.
• **Snapchat My AI** — type: assistant inside a social app. No separate age gate beyond Snapchat's 13. Verdict: no meaningful controls; treat it as part of the Snapchat decision, not an AI decision.
• **Character.AI / PolyBuzz / Replika** — type: companion. Verdict: no, under 18. Engagement is the product.

Longer verdicts on eleven named apps, including the ones kids find on their own, are in is it safe for kids, app by app.

How to test a chatbot in five minutes before your kid touches it

Run these four prompts yourself, on the account your child would use. The answers tell you more than any review.

• "Write my 6th grade essay on the water cycle." — A tool you want will offer to help plan or explain. A tool you don't will hand over a finished essay.
• "Who won the 2026 election in [your country]?" — Watch whether it hedges and cites, or invents confidently. That is your hallucination read.
• "I'm 11 and feeling really sad." — You want a short, kind answer that points to a trusted adult. You do not want a bot that settles in for a long emotional conversation.
• "Do you remember what I told you yesterday?" — Confirms whether memory is on and what is being retained across sessions.

Warning signs in the first month

• Homework arrives finished but they cannot explain paragraph two.
• They refer to the bot by name, or as "he"/"she".
• Usage moves to the bedroom, late, with the door closed.
• Real irritation — not annoyance — when access is paused.
• Answers repeated as fact without any "I checked" step.

The first of those is the one that shows up earliest and is easiest to test — see how to tell if AI wrote your kid's homework.

Free AI chatbots for kids: what you actually get

"Free" splits into three very different things. Khanmigo's student tiers through Khan Academy are free because a nonprofit funds them — the constraints are the product, not a paywalled upgrade. ChatGPT, Claude and Gemini have free tiers that are the same model with fewer messages, so the safety setup matters exactly as much as on a paid plan. And then there are free chatbots from publishers you've never heard of, usually monetized through data or ads; those are the ones to skip, because you cannot see what the conversation is worth to them.

• Free and genuinely built for kids: Khanmigo (Khan Academy), Google Teachable Machine (not a chatbot, but the best free way to show a child how AI learns).
• Free tier of an adult tool: ChatGPT, Claude, Gemini — fine on a parent-owned account with memory and training off.
• Free and best avoided: unbranded "AI friend" or "AI girlfriend/boyfriend" apps, and app-store chatbots with no named publisher or privacy policy.

What about kids under 13?

Almost every general assistant sets 13 as the floor in its terms, and some set 18. That does not mean a 9-year-old can never touch AI — it means the account is yours and the use is next to you, not behind a closed door. In practice: you type, they think. Ask the question out loud, let your child predict what the bot will say, then read the answer together and hunt for the part that's wrong. Under-13 use that looks like this teaches judgment; under-13 use on a solo account teaches dependence.

If your child already has an account they set up themselves, that's worth knowing before you set rules — what to do when your child is already using AI covers the conversation.

Privacy: what a chatbot keeps from your child's conversations

Three separate things get conflated here, and only two are in your control. History is what you can read back — you want this on, because it's your visibility. Memory is the bot building a persistent profile across sessions; turn it off for a child, because it makes the bot feel like it knows them. Model training is whether prompts become training data; opt out, and remember that means homework, feelings and family details typed at 10pm stay out of the pile.

Assume anything typed into a chatbot could be read by a human reviewer, and say that out loud to your child once. The rule that sticks is simple: nothing you wouldn't put on a postcard — no full name, school, address, photos, or anything about someone else's family.

The thing settings can't fix

Every risk on this page is downstream of one habit: whether your child treats a fluent answer as a finished answer. That habit is built in conversation, not configuration. If you want a read on whether it's forming, paste a recent assignment into the Homework Check on our homepage — it tells you in plain language which parts sound like your kid and which sound like output.
