Why "coprimes"?
Two numbers are coprime when their only common factor is 1 — distinct, yet perfectly paired. That's our model for learning: Math, Logic and English are distinct disciplines sharing one common factor — a child who truly understands.
Understanding is the only thing worth optimizing
We started COPRIMES with an uncomfortable observation: a child can score well at school for years while quietly failing to understand. Predictable exams reward rehearsal. Drills reward repetition. And the gap only shows up later — usually at the worst possible time.
AI makes this urgent. The mechanical parts of every subject are being automated; what remains valuable is exactly what rote learning never built — conceptual depth and the ability to reason. So we built a platform that's structurally incapable of rewarding fakery: baseline tests that find the truth, scoring that separates knowing from guessing, mastery tests the AI tutor can't help with, and revision timed to the forgetting curve.
And because software alone leaves parents alone, every family gets parent academic support via chat. AI-powered, human-guided — that's the whole company in four words.
What we will and won't do
We reward accuracy, not hours
Coins and XP follow first-attempt correctness and genuine completion — never time-on-screen.
We tell you the truth
If the data shows a gap, your dashboard says so. If tutoring isn't needed, we say that too.
We design for the long game
The 14-day revision test exists because we measure ourselves on what a child remembers.
No answer engine
Our AI never hands over solutions, and it goes silent during anything that counts.
No dark patterns
No buried cancellation, no upsells inside a child's app. Cancel anytime before the trial ends and you won't be charged. Ever.
No busywork
If a worksheet doesn't serve a lesson objective, it doesn't ship. English covers three skills deeply, not ten thinly.
