Built on Knowledge Space Theory

Find the one missing idea that's blocking everything else.

Mastry AI is an adaptive learning platform that maps exactly what a student knows, pinpoints the prerequisite gap holding them back, and builds a personalised path to close it — starting with Class 10 & 12 mathematics.

The problem

Most students aren't behind. They're missing one link in the chain.

Traditional learning moves forward on a schedule, not on readiness — so small gaps compound silently until a subject feels "impossible."

🎯

No personalisation

One pace, one path, for every student — regardless of what they already know or where they're actually stuck.

🗣️

Access & language gaps

Poor teacher-to-student ratios and language barriers limit how much individual attention a student can realistically get.

🧩

Invisible prerequisite gaps

A single missing concept from months ago can quietly block mastery of everything built on top of it.

THE CORE IDEA

The prerequisite knowledge graph — the chain-of-thought for learning.

Every topic is broken into subtopics with explicit prerequisite relationships, built using Knowledge Space Theory (Doignon & Falmagne). Instead of guessing, Mastry AI diagnoses exactly where a student's knowledge state sits on that graph.

The result: a sequence of lessons ordered by "marks-per-hour" — the fastest route from where a student is today to visible score improvement.

Inside the engine

What the diagnostic actually measures

A chapter-wise diagnostic estimates mastery per topic, then the engine sequences lessons by expected score gain per hour of study.

One graph, three ways to use it

Diagnostic

A fast, chapter-wise read on exactly where a student stands.

  • Adaptive question selection
  • Instant topic-level mastery score
  • Identifies the single blocking gap
Core product

The full learning loop — diagnose, learn, practice, re-check.

  • 70+ glossary-first authored lessons
  • Inline hints after incorrect answers
  • Step-by-step working & feedback
  • Ask-a-doubt, personalised to the learner

Curriculum infrastructure

The prerequisite graph and authoring framework as a foundation for any subject.

  • Knowledge Space Theory graph engine
  • 13-rule lesson authoring framework
  • Extensible beyond Class 10 math
How it works

From first question to visible score gain

1

Take the diagnostic

A short, chapter-wise adaptive test locates the student on the prerequisite graph.

2

See the real gap

The engine surfaces the specific prerequisite concept that's blocking progress — not just a weak topic.

3

Learn in sequence

Lessons are ordered by marks-per-hour, so study time goes to the highest-impact concept first.

4

Practice & re-check

Step-by-step marking, inline hints, and doubt-clearing confirm the gap is actually closed.

Stop guessing what a student needs next.

Mastry AI turns a single diagnostic into a clear, personalised path — for Class 10 and 12 students today, and any subject tomorrow.
