We Don't Hand Out Answers. We Teach Thinking.
Every coach follows one rule: guide with questions, one step at a time — so the answer is something your child builds, not something they copy.
Side by side
The Same Question, Two Very Different Teachers
Ask a typical chatbot and an OpenKids coach the exact same thing — then look at what your child actually walks away with.
A typical chatbot
The full answer, instantlyThe answer got copied. Nothing got learned.

Guided, step by stepThe answer is earned — so it sticks.
The evidence
The Research We Build On
None of this is our invention. We took what learning science has already proved and engineered it into every coach.
Attempt First, Then Guidance
What the research says
A randomized controlled study published in PNAS (~1,000 students) found that answer-giving AI made students score 17% worse once it was removed — while a guided version lifted practice performance with no such harm.
What we build in
Every coach asks what your child has tried before explaining anything. Full solutions only unlock after a genuine attempt — we call it the earned reveal.
Socratic Questioning
What the research says
A randomized trial at Harvard found an AI tutor's learning gains came from its pedagogical wrapper — the questions it asks — not from the raw model underneath.
What we build in
That wrapper is our product: one question per turn, one step at a time, the plan stated up front. These are hard rules written into every coach's system prompt.
Retrieval & Spaced Review
What the research says
Decades of cognitive science agree on two of the most reliable effects in learning: testing yourself beats re-reading, and spacing reviews out beats cramming.
What we build in
The mistake book brings every error back later as a re-test with new numbers and a new context. An entry only graduates after two correct re-tests.
From knowing to doing
The Coaching Toolkit
Understanding is step one. Three mechanisms turn "I get it" into "I can do it".
Practice & Marking
Once a concept clicks, the coach writes fresh questions at exactly the right level and marks the answers — praising the strategy first, then pointing at the one thing most worth fixing.
The Mistake Book
Every genuine error is logged as a misconception, not a failure. It comes back later with new numbers and a new context — and only graduates after your child gets the re-test right twice.
The Feynman Check
The final proof of understanding: your child explains the idea back in their own words, as if teaching it. The coach listens for the gaps, then asks the one question that exposes them.
One rule, every age
One Question, Four Ages
Coaches adapt tone, depth and pace to your child's age. Here is how the same fractions question opens at each stage — the first two are generated live by our demo engine.
Tone at this agePlayful and concrete — one tiny idea at a time, everyday pictures like pizza slices.
Generated live by our demo engineGreat question! Fractions — nice, this is one of my favourite things to teach.
Picture a pizza cut into equal slices. The bottom number says how many slices there are in total. The top number says how many slices you get.
Your turn: If a pizza is cut into 8 equal slices and you take 3, what fraction of the pizza is that?
