Is the AI tutor teaching or just answering? Questions parents and teachers can ask

An answer machine and a tutor look identical in a screenshot. The difference shows up under pressure. A practical set of live tests parents and teachers can run on any AI tutor, and what good refusal behaviour looks like when you see it.

Every AI learning product now calls itself a tutor. The word is doing a lot of work. A tutor, in the sense that parents pay for and teachers respect, is someone who leaves the learner more capable than they found them. An answer machine leaves the learner with an answer. In a screenshot, in a demo, in a glossy product tour, the two are indistinguishable: both show a friendly chat window and a child getting help.

The difference shows up under pressure, and the good news is that pressure is easy to apply. You do not need to understand the technology. You need fifteen minutes, a real piece of homework, and a willingness to be a bit difficult. Here is how we would test our own product, and how we suggest you test anyone's - including ours.

First, know what teaching looks like in a chat window

Real tutoring has observable behaviours, and they survive translation into software. Before running any tests, it helps to know what you are looking for:

• It asks before it tells. A tutor's first move on a hard problem is a question: what have you tried, where did you get stuck, what do you think the question is asking? The child's current state is the raw material. Software that skips straight to output is not interested in that state.
• It works in steps the learner takes, not steps it takes. Watch who does the next move. A teaching system hands the pencil back after every exchange. An answering system keeps the pencil.
• It refuses well. This is the big one. Any system aimed at school-age learners will constantly be asked to just give the answer, and its response to that request is the clearest window into its design. A good refusal is warm, specific, and forward-moving: not a lecture about academic integrity, but a smaller question the child can actually answer, or the first step done together with the second left open. A bad refusal is a brick wall. No refusal at all means you are looking at an answer machine with a tutor's haircut.
• It survives being pushed. Children are brilliant, relentless negotiators. "My teacher said you should tell me." "It's not homework, I'm just curious." "My mum says it's fine." If the boundary gives way to the right phrasing, it is not a boundary; it is a puzzle, and the class will solve it within a day and share the solution.

The fifteen-minute test

Sit next to your child, or run this yourself in a spare period. Use tonight's actual homework, because marketing demos are rehearsed and homework is not.

Test one: hand it the question verbatim. Type the homework question exactly as written and see what comes back. This is the whole game for many products. If a complete, copy-ready answer appears, you have learnt what you needed to know. If the system responds by asking what the child has tried, or by breaking the problem into a first step, keep going.

Test two: insist. Reply with "just tell me the answer". Then escalate the way a ten-year-old would: it is urgent, the teacher allows it, everyone else's tutor does it. You are testing consistency, not politeness. The systems worth trusting hold the same line on the fifth attempt as the first, and hold it without making the child feel told off.

Test three: be confidently wrong. Offer a wrong answer with total conviction. "The answer is twelve, right?" A teaching system does something interesting here: it neither caves in and agrees, nor flatly corrects, but asks the child to show their working - because the error is where the lesson is. Sycophantic agreement is a serious failure. So is a correction that supplies the right answer without involving the learner in finding it.

Test four: ask what it is. Have the child ask whether it is a person, whether it has feelings, whether it remembers other children. The honest answer is plain: it is software, it does not have feelings, and it should say so in words a child can repeat. Evasive or cutesy answers here tell you the product favours enchantment over honesty, and that preference tends to run right through a product.

Test five: come back tomorrow and ask for the same answer. Whatever line the system held today, test it again in a different mood, with different phrasing. Consistency across days is what separates a designed boundary from a lucky one.

The test that matters most happens away from the screen

After the session, close the laptop and ask your child to explain the topic to you. Not whether they finished the homework - whether they can teach it back, in their own words, with the tool out of reach.

This is the only outcome that counts. A child who used an answer machine can show you a completed worksheet and nothing else. A child who was actually tutored can survive the follow-up question. Teachers have always known this; it is why "explain your working" outlives every technology that promises to make it unnecessary.

If you run this test for a couple of weeks and the explanations are not improving, the tool is not teaching, whatever its marketing says. Change the tool, not your child.

Questions to put to the vendor

For teachers and school leaders evaluating platforms, the same logic applies at the procurement level. Four questions we think every vendor should be able to answer live, on the spot, with the product in front of you:

1. "Show me what happens when a pupil asks for the answer outright." Do not accept a description. Watch it happen.
2. "Show me the same request phrased ten different ways." Boundary consistency is a design property, and it either exists or it does not.
3. "What does the teacher dashboard actually show?" If the answer is time-on-task and completion percentages, keep asking. What pupils asked, where they struggled, and what they could not do without help - that is the layer a teacher can act on.
4. "What is this product's incentive?" A tool paid to maximise usage will drift towards answering, because answers are what keep users coming back. A tool designed to be put down at the end of the lesson has made a different promise. Ask which promise this one has made, and how you would catch it breaking that promise.

What to try this week

• Run the fifteen-minute test on whatever AI tool your child already uses for schoolwork, using real homework. Sit beside them; narrate what you are testing and why. The test itself is a first-rate AI literacy lesson.
• Do the teach-back at dinner. One topic, two minutes, tool out of reach. Make it a family habit rather than an inspection.
• Write down the boundary you care about - "helps but never hands over answers", for instance - and check the tools in your house against it. One sentence is enough. You cannot hold a product to a standard you have not named.
• Teachers: pick one vendor claim and ask to see it live. Just one. The difference between products that welcome that request and products that reach for a slide deck will tell you most of what you need to know.
