Master concepts.
Not just test scores.
20 focused minutes a day. A learning path built from your child's own baseline test. And mastery that's re-checked 14 days later — so it actually lasts.

Three subjects. One thinking child.
AI now does the rote work. What's left — and what matters — is a child who can reason. Every COPRIMES subscription builds that with three subjects working as one.
Math
Aligned to your exact school curriculum, then paced to your child.
Logic
Our proprietary K–10 curriculum in reasoning and problem-solving.
English
Reading, Vocabulary & Grammar — the skills that power everything else.
From first login to lasting mastery
Start with the truth: the Adaptive Baseline Test
A low-pressure diagnostic that adapts question by question, finds your child's real starting point, and sends you a detailed PDF report.
- No pass or fail — just an honest map of strengths and gaps
- One ABT per subject, each path calibrated separately
A path made for one child: yours
The journey starts where your child is — even if that's a grade back in one strand or two ahead in another. You can reshape it anytime through parent academic support.
- Above grade, below grade, Olympiad or gap-first
- Support-added lessons appear right in the path, in blue
Every lesson, four tracks
Learn it actively. Practice it deeply. Play it for fluency. Prove it in a timed Review. Earn coins and XP for accuracy at every step.
Try the switcher → it's a tour of the real lesson page.
Drag the slider — watch how 1/2, 2/4 and 4/8 always shade the same area of the bar.

Mastery, re-verified 14 days later
Memory fades on a schedule — so we revise on a schedule. Every mastered lesson gets a revision test two weeks on. Pass it, and the concept is yours for good.
- Struggle on the revision? The path quietly re-teaches
- Both scores visible to you, always
Fun, but firm.
Coins and streaks make children show up. Four quiet guardrails make sure every score means real learning.
AI off during checks
The Socratic tutor guides learning and practice — and goes silent on every concept check and test.
Two attempts, both scored
First-attempt accuracy is tracked separately — the difference between knowing and guessing.
Protected review tests
Timed, tab-switches tracked, two pauses max. A mastery score means what it says.
The 14-day proof
Mastery only counts if it survives the revision test two weeks later.
An app worth coming back to, every day
Leaderboards, levels, streaks and badges — every one of them earned through accuracy, never screen time.
One screen that answers "how's math going?"
The curriculum matrix lights up lesson by lesson — green for mastered, amber for in-progress, red where attention is needed, and blue for lessons added just for your child through parent academic support.
- Drill into any lesson for first-attempt accuracy and time per question
- ABT and lesson reports, downloadable as PDFs
Parent academic support, one chat away
Every family gets parent academic support via chat, with full view of your child's data. Ask about progress, reports and learning paths, or request above- or below-grade lessons, specific worksheets, or a full plan — and the path is adjusted accordingly.
Most platforms hand you software and disappear. We don't.
Everything included. One price.
All three subjects, every track, the parent dashboard, reports and parent academic support — from $16.6/month at launch pricing.

Common questions
Is the baseline test stressful for my child?
No — it's adaptive and framed as a "starting point finder," not an exam. It exists so your child never sits through lessons that are too easy or too hard.
Won't the AI tutor just give the answers?
It can't. The tutor is Socratic — it nudges with questions — and it's switched off entirely during concept checks and review tests. Every score is your child's own thinking.
How much time does it take each day?
About 20 focused minutes. The platform rewards accuracy and consistency, never raw hours — the consistency map makes the habit visible and worth keeping.
