How Old Do You Have to Be to Use Claude AI? (2026 Guide)

The short answer: Anthropic says 18+

Anthropic's Terms of Service (the company that makes Claude) state that Claude.ai is intended for users who are 18 years old or the age of majority where they live. That is the same stance as OpenAI for ChatGPT and most other major AI chatbots.

Worried you are behind? You are not: most parents are only just starting with AI, according to our latest data from real families.

There is no Claude for Kids app. No kids mode. No parental dashboard. No under-13 flow like you get with Google Family Link or Apple Screen Time.

What this means in practice: a child under 18 cannot sign up for their own Claude account without a parent's involvement, and even with a parent's permission, you are using it outside Anthropic's intended audience.

🔒 Safety Note: The 18+ rule is a legal and safety boundary, not a technical one. A child could click through signup. But doing so puts them on the wrong side of the Terms, and if something goes wrong, you have no recourse. Always use your own account and supervise directly.

Why Anthropic set the age at 18

This surprised me the first time I read Anthropic's safety documentation. The 18+ cutoff is not because Claude is dangerous. It is because Anthropic has not built the things you need to make an AI safe for minors:

• No age-appropriate content filtering. Claude's safety model assumes an adult user who can handle discussions of history, violence, mental health, and mature topics in context. Your 6-year-old does not need the same defaults.
• No COPPA compliance. The Children's Online Privacy Protection Act requires specific data handling for users under 13. Claude does not have that infrastructure.
• No parental controls. You cannot limit what topics Claude discusses, set a time limit, or review your child's conversation history from a separate dashboard.
• Training data includes adult content. Claude's knowledge base includes everything from medical textbooks to adult literature. The filters are designed to stop misuse, not to make it kid-appropriate.

That is a fair policy. Making an AI genuinely safe for kids is a massive undertaking. Tools like Khanmigo and Synthesis Tutor have done it, and their products look nothing like Claude as a result.

Can kids use Claude with a parent?

Practically, yes, and most parents I know are doing exactly this. You sign in to your own account, your child sits next to you, and you use Claude together for a specific task. This is what Anthropic calls supervised use, and it is how we have done it for the past year.

The important framing: your child is not using Claude. You are using Claude, and your child is involved. You read the prompts together. You read the responses together. You close the tab when you are done.

This is different from handing a 10-year-old your iPad and letting them chat with Claude on their own. That crosses from supervised into unsupervised, and it is the thing the 18+ policy is trying to prevent.

Here is a 3-minute walkthrough of my 8-year-old building three different projects with Claude Artifacts. Worth watching before you sit your own kid down with it.

What we have seen: using Claude with my 8-year-old

We have used Claude together for about a year now. The contexts where it has worked well:

Homework fact-checking (not homework doing)

When my son writes a paragraph about the Vikings for school, we sometimes paste it into Claude and ask, "Are any of these facts wrong?" Claude catches things like incorrect dates or misattributed inventions. It does not rewrite the paragraph. My son fixes what he got wrong.

This works because I am driving. I am the one typing the prompt. He is the one reading the feedback and deciding what to change.

Reading comprehension practice

Claude is excellent at generating comprehension questions from a text. I will paste in a chapter from his school reader and ask Claude to create five questions at an 8-year-old reading level. He answers them out loud. If he gets stuck, we ask Claude to explain the answer.

Creative writing prompts

He loves writing stories about football matches between imaginary teams. Claude is great at generating prompts: "You are a young footballer who discovers your boots make you invisible when you wear them to training." He takes the prompt and writes the story. No AI touches his actual writing.

Building things with Claude Artifacts

The sessions where we have seen the most engagement are when Mateo builds something, rather than just asks something. Claude has a feature called Artifacts — when you ask it to make something interactive, a working panel appears beside the chat. No download, no app, no separate account for the child.

Last week he built a European flags quiz, then changed the colour and added South American flags with two more prompts. Then a working Tetris game (he had never heard of it — he worked out the controls himself). Then a revision quiz on exactly the shapes coming up in his school test that week, built in 20 seconds. Three sessions, all his ideas. Full walkthrough with the three exact prompts →

Where we stopped using it

Early on, I tried using Claude to help him understand why a math problem was wrong. Claude explained it in a way that was too abstract. We went back to a proper kids math tool for that (Synthesis Tutor works much better for that specific use case).

💡 Parent Insight: Claude is a general-purpose tool, not a teaching tool. For subjects where your child is actively learning fundamentals (phonics, basic math, handwriting), use a kids-specific tool. Use Claude for the parent-adjacent work: explaining something, generating examples, checking facts.

Is Claude safer than ChatGPT for kids?

In our testing, yes, but the gap is narrower than most safety reviews suggest. I wrote a full side-by-side comparison here: ChatGPT vs Claude for kids.

The short version: Claude refuses more inappropriate prompts, is more cautious with mental health and self-harm topics, and is less likely to generate graphic content even when jailbroken. Anthropic's Constitutional AI approach is visibly more conservative.

But both are built for adults. Neither has a kids mode. Both can be jailbroken by a determined 14-year-old. If your only options are Claude or ChatGPT, Claude is my pick for supervised family use. If you want something actually designed for kids, neither is the right answer.

If your child wants to use Claude, here is what I would do

The most common scenario: your 10, 12, or 14-year-old has seen Claude at school or on TikTok and wants their own account. Here is the decision tree I use:

Under 13 — Full supervision onlyNo independent account. Use yours, supervised, for specific tasks only. Close the tab when done.13 to 15 — Supervised with them driving

Still your account, still supervised, but you can start doing longer sessions together. Let them drive the prompts. You read every response.

16 to 17 — Solo with guardrails

Your account still, but they can use it for homework help on their own for short periods. You check the conversation history weekly. Set a rule that any school work using Claude must be disclosed to the teacher. Teachers themselves are a different case: Claude is now free for verified US K-12 teachers, with the AI in the adult's hands rather than the child's.

18+ — Their own account

Their own account, their own life. At this point they can sign Anthropic's Terms themselves.

A quick safety checklist before any session

• Sign in to your own account, not a shared family one
• Turn off the "allow Claude to learn from this conversation" toggle in Settings if your child is involved (protects their inputs)
• Agree on the topic before starting the prompt
• No real names, school names, or addresses in any prompt
• Close the tab when finished, do not leave the session running

🔒 Privacy Note: We never use our kids' real names with Claude. My son is "the 8-year-old" or "my student" in every prompt. Anthropic's policy is good, but the safest approach is to give the AI nothing personally identifiable about your child in the first place.

What Anthropic does well for families (despite the 18+ rule)

Credit where it is due. Claude has a few features that make supervised family use easier than it is with most AI chatbots:

• Conversation history is private. Anthropic does not train on your conversations by default unless you opt in.
• The refusal messaging is kid-appropriate. When Claude declines to answer something, it does so politely. No scary warnings.
• It handles "explain like I'm 8" really well. You can ask Claude to rewrite any response at a lower reading level and it does it cleanly.
• The interface is simple. No ads, no upsells, no embedded stores. Just a chat window.

The bottom line

The official answer to "how old do you have to be to use Claude AI" is 18. The real-world answer for families is: you can use Claude with your child as long as you are the account holder, you are physically present, and you treat it as a tool you are using together.

For supervised use with an 8, 10, or 12-year-old, Claude is the most responsible general-purpose AI I have tested. It is not designed for kids. But if you are going to use any AI with your child, I would rather it be this one than most of the alternatives.
