The calculus was right. The slip came before it.
Not just wrong.
Exactly why.
MYKO marks every line of your handwritten working — photo in, verdicts out — then traces each mistake to the prerequisite that actually broke, and drills you exactly there.
No card needed. From US$38/month after your free week.

The problem
A grade can’t tell you
what broke.
4/7 on a calculus question says marks were lost — not where the maths gave way. So students redo the topic, score 4/7 again, and decide they’re “bad at calculus”. Usually they aren’t. Something two chapters earlier is.

The name
Learning science has a name for the person just ahead of you — the knowledgeable other: close enough to know exactly where you are, far enough ahead to know what comes next. Every strong student has one. Now yours doesn’t depend on luck.
MYKO — My Knowledgeable Other, after the “more knowledgeable other” of Vygotsky’s learning theory.
How it works
Paper in. Root cause out.
Work on paper
Real exam conditions: pen, paper, full working. When you’re done, photograph the page.
Every line, marked
Not just the final answer — each step of the method gets its own verdict.
The real gap, found
Each slip is traced down the prerequisite graph to the skill that actually failed.
Practice that aims
Your next session drills the root, not the symptom — a few questions a day, spaced so it sticks.
01 · Marking
Every step, marked.
A right answer with broken method gets caught. A wrong answer with sound method gets credit. That’s how a real examiner marks — and how MYKO marks.

The calculus was right. The slip came before it.
Correct Method flag Method unsure Partial Wrong
Five verdicts, per step. When the photo is ambiguous, MYKO says method unsure and asks — it never guesses your working into a grade.
02 · Diagnosis
The real gap. Found.
Getting differentiation wrong rarely means differentiation is the problem. MYKO walks the mistake down a prerequisite graph — 546 skills deep — to the deepest skill that’s actually broken.

The real gap: negative indices, not differentiation.

Fix the root and it stays fixed.

A few a day. Aimed.
Short sessions of exam-style questions, weighted to your weakest verified gap, what’s due for review, and what’s next in the syllabus. Answered on paper, marked the same way.

independent checks on every question before it reaches you
Every question is written against the syllabus, then re-derived blind by a second, independent AI that never sees the intended answer — and reviewed by a human before publishing. Disagreements don’t ship.

Your syllabus.
Not someone else's.
Every question, skill, and prerequisite is built for a specific exam board — not a generic “high-school maths” blob.

FAQ
Fair questions.
What is MYKO?
MYKO — short for "My Knowledgeable Other" — is an adaptive maths practice platform. You photograph your handwritten working and get step-by-step marking, plus a diagnostic that pinpoints your exact gaps and targets them with practice. IB Mathematics is live today, with VCE and Singapore MOE curricula rolling out.
How is MYKO different from apps that just give you the answer?
Answer-finder apps hand you the result. MYKO reads YOUR handwritten working and marks it line by line, so you see where your method breaks down — not just whether the final answer is right. It then traces that mistake back to its root-cause skill and gives you practice that fixes the underlying gap.
How does the step-by-step photo marking work?
You solve a problem on paper and photograph your working. MYKO reads each line, marks it step by step, and identifies the first place your reasoning breaks down. A wrong method is flagged even when the final answer happens to come out right — because the method is the skill.
Which curricula does MYKO cover?
Worldwide: IB Mathematics — Analysis & Approaches (AA) and Applications & Interpretation (AI) are both live at SL and HL. Local curricula are rolling out by region: VCE Mathematical Methods and Specialist Mathematics (Australia) and Singapore MOE, with more to follow.
Can MYKO place me wherever I am in the course?
Yes. The adaptive diagnostic places you at your real level, and every practice session targets your weakest skills — whether you are just starting the course or revising for final exams.
What do I need to use MYKO?
Just pen and paper, a device with a camera, and a browser. You do the maths by hand, photograph your working, and MYKO marks it — no special hardware and no app to install.
How much does MYKO cost?
Every account starts with a 7-day free trial — no credit card needed. After that, MYKO is a monthly subscription (with an annual option); current pricing for your region is shown when you sign up, and you can cancel anytime.
