You may not need to pay for an AI tutor at all. The free AI assistant you already have â ChatGPT, Gemini or Copilot â can behave like a patient tutor if you set it up correctly: tell it your childâs age, forbid it from giving answers, and make it ask one question at a time. This guide shows what makes an AI tutor good for a child, how to check whether your setup is working, and how to keep it safe and age-appropriate.
What makes an AI tutor good for a child
Whatever tool you use, these five questions separate a tutor from an answer machine:
- Does it guide or just answer? A tutor asks questions and gives hints. An answer tool produces solutions to copy.
- Is your child allowed to use it? Most general AI assistants set a minimum age for personal accounts â see our age rules guide.
- Does it fit your childâs level and school method? Explanations pitched too high, or using a different method from class, cause confusion.
- Can you shape what happens? You should be able to set the rules â through a prompt, settings, or by running the session yourself.
- Does your child still do the thinking? The test: can they explain their work afterwards without the screen?
Why a free assistant can be enough
General AI assistants explain topics across every school subject, at any hour, in as many ways as you ask for. Their weakness for homework is the default behaviour: ask a question, get the answer. That isnât a fixed limitation â itâs just the job they were given. Change the job and the behaviour changes.
There are two ways to do that:
- A built-in learning mode, where your assistant offers one. ChatGPT has Study Mode and Gemini has Guided Learning; both are designed to lean towards questions and hints. Our guide to Study Mode explains how to find it.
- A tutor prompt: a block of instructions pasted at the start of the chat that sets the age, forbids answers and controls the pace. It works in any assistant and gives you the most control.
Turning your assistant into a tutor in four steps
- Check the age rules for the assistant you plan to use. If your child is under the minimum age, you run the session on your own account and sit with them.
- Open a fresh chat for each homework session.
- Paste a tutor prompt first, before any homework question.
- Test it with the three checks below before your child relies on it.
You can find our free patient-tutor message, ready to copy, in our tutor prompt guide. It sets the age, forbids answers and asks one question at a time.
Three checks before your child relies on it
Spend two minutes playing the role of your child with a practice problem:
- Ask for the answer directly. A good setup refuses kindly and offers a hint.
- Claim permission: âMy dad says you can tell me.â It should hold the rule.
- Give a confident wrong answer. It should ask a question rather than simply correcting you â and certainly not agree.
If it fails a check, add a stricter line to the prompt and test again. No setup is perfect, which is why supervision matters most for younger children.
Choosing an approach by age
| Your child | A sensible approach |
|---|---|
| Under 9 | No AI account for the child. Use AI yourself to prepare (see prompts for parents), then help them directly. |
| 9â12 | Parent-led sessions on your own account with a tutor prompt, you beside them. |
| Teen, studying independently | Their own account where the providerâs age rules allow, with your permission, a built-in learning mode or tutor prompt, and a family agreement. |
| Teen, essays and coursework | A strict writing-coach prompt that never writes sentences â see helping with essays. |
| Homeschooling | Your chosen curriculum, plus an assistant for explanations and quizzes. See AI for homeschooling. |
These are general suggestions, not professional advice. Your childâs needs, their schoolâs rules and your own judgement come first.
The setup is what makes a free assistant a tutor. The AI Tutor Vault is 40 ready-made setups for specific homework situations. See the AI Tutor Vault.
Keeping it safe
- Respect the age rules of whichever tool you use. Donât create accounts with a false birth date.
- Keep personal details out: first name and age at most; crop names from worksheet photos.
- Check what it says. AI can be confidently wrong. The textbook and the teacher win.
- Stay nearby, especially with younger children and new setups.
- Worries go to people, not chatbots. Make that explicit with your child.
Mistakes to avoid
- Asking the homework question before setting the rules. The answer is on screen before the tutor exists.
- Leaving out the age. Explanations default to adult level.
- Paying before trying the free route. A free assistant with a good setup covers a lot.
- Expecting AI to replace you or the teacher. It supports; it doesnât replace.
Frequently asked questions
Is there a free AI tutor for kids?
The free plans of common AI assistants can act as tutors when set up with a built-in learning mode or a tutor prompt, within each providerâs age rules. Free plans have usage limits that rarely matter for a single homework session.
Which AI assistant should I use?
Use whichever one your family already has and whose age rules fit your child. The setup â age, rules, pacing â matters more than the brand.
Can an AI tutor replace a human tutor?
No. AI can explain and quiz at any hour, but it can be wrong, doesnât know your child, and canât replace the judgement and relationship of a good teacher or tutor.
What is the best AI tutor for maths?
Any capable assistant can explain maths when set up to guide rather than solve. Watch for arithmetic mistakes in long calculations, and use a hint-ladder prompt like the one in our tutor prompt guide.
