A mastery-based progression from counting to calculus and beyond — guided by Trinity AI, the voice tutor engine that finds the exact crack in your understanding and repairs it before you build on top of it.
No signup required for the demo. Speak or type your answers — voice runs on-device. Ages 5 to 95.
Math Foundation is a Trinity AI math tutor and math intervention software product that maps math as a dependency graph, diagnoses the misconception behind wrong answers, repairs prerequisite gaps, and uses mastery gates before learners advance.
For families, tutors, homeschool learners, and adults who want personalized math learning with unlimited tutoring and spaced review.
For teachers and schools that need a classroom math gap heatmap, roster-based intervention groups, and evidence of repaired prerequisite skills.
The product combines structured curriculum, Trinity AI tutoring, misconception diagnosis, mastery evidence, and parent or teacher dashboards instead of acting like a generic chatbot or worksheet app.
Traditional classrooms move on when the calendar says so, not when you're ready. One missed concept in grade 4 becomes "I'm not a math person" by grade 9. Math Foundation never moves on until the foundation holds.
Every concept in mathematics, mapped as a dependency graph of atomic skills. You always know exactly what you've mastered, what's next, and why.
A patient voice tutor powered by Trinity AI explains, listens, and re-explains differently — Socratic when you're close, direct when you're stuck. Available every hour you are.
You don't pass with 70%. A skill is mastered when you can do it reliably, explain it, and apply it — then we keep it alive with spaced review.

Most apps say "incorrect — try again." Math Foundation reads the mistake itself and names the exact misconception behind it. Watch:
Wherever you start — age 5 or 50 — a diagnostic places you on the graph, and the path adapts around your gaps. Here's a tiny slice of it.
A 9-node slice of the full graph — the alpha graph now includes 600 authored skill briefs across 60 clusters, with the production roadmap extending toward 2,400+ atomic skills.
A conversational diagnostic finds your true frontier — often surprising. Adults routinely discover gaps from decades ago that explain everything.
Your tutor teaches the skill aloud, checks understanding with questions, and watches you work. Wrong answers aren't failures — they're diagnostic data.
Demonstrate mastery to unlock the next skill. Spaced reviews resurface old skills at exactly the right interval so the foundation never erodes.
Stay ahead of class, or quietly repair the gaps class left behind.
Finally fix "I'm not a math person." Start where you actually are, judgment-free.
See each student's real skill graph. Teach to the gaps, not to the middle.
A complete, sequenced math curriculum with a tutor who never tires.
Free to start. Affordable to master. Classroom and school bundles scale the same mastery graph without per-teacher setup pain.

The full experience
Up to 6 learners, one subscription
Math Foundation can start with one teacher tomorrow and grow into a school-wide mastery layer. Every bundle includes class codes, teacher dashboards, roster import, and gap heatmaps.
For one teacher proving the model with a class, intervention group, or tutoring cohort.
For a year level, department, or multi-class intervention rollout.
For schools that want one mastery progression across grades and support programs.
Anyone from 5 to 95. Kids working ahead of (or catching up to) school, adults finally repairing decades-old gaps, teachers who want to see each student's real skill graph, and homeschool families who need a complete sequenced curriculum. The diagnostic places you where you actually are — no judgment, no grade labels.
Two things. First, the mastery gate is real: you cannot advance past a skill you haven't proven on questions you've never seen, so gaps can't silently accumulate. Second, the tutor diagnoses your specific mistake — answer 35 to 42 − 17 and it recognises the classic column-subtraction bug and re-teaches that, rather than just flashing "incorrect, try again."
Explorer is free forever: full diagnostic, skill graph placement, three tutored lessons a week, and unlimited self-paced practice. Foundation is $19 AUD/month for unlimited Trinity AI voice tutoring and spaced reviews. Family covers six learners for $49 AUD/month. Classroom bundles start at 30 seats, grade-team bundles at 150 seats, and school bundles at 500+ seats.
No — it makes them work better. Classrooms have to move at one speed; Math Foundation repairs and reinforces at yours, then hands teachers a live map of every student's gaps so class time goes where it's needed. Many of our design choices come from teachers, and the educator dashboard is built for them.
The full graph maps 2,400+ atomic skills from first counting through university-level mathematics — arithmetic, fractions, algebra, geometry, trigonometry, calculus and beyond. One unbroken dependency chain: wherever you start, the path to anywhere else is already mapped. The free demo plays a real 17-skill slice of it.
Families and classrooms can buy now through Stripe. Grade teams and schools can calculate a discounted annual rollout, pay through Stripe Checkout, and send onboarding details in the same flow.
