Every feature, explained in depth

Seven layers.
One compounding platform.

From SM-2 spaced repetition to Duolingo-style doubt resolution — every feature has been engineered specifically for India's 38M+ competitive exam students and 1.5M+ schools. Here's exactly how each one works.

Core Engine · SM-2

Memory Engine &
MSI Scoring

The foundation of everything. Rattafy's memory engine runs the SuperMemo-2 algorithm — the same science behind Duolingo and every world-class memory system. Combined with our proprietary Memory Strength Index (MSI), it gives every student a brutally honest per-topic score of what they actually know vs. what they think they know.

  • SM-2 algorithm: each card's interval is calculated from your exact recall quality (0–5 grade)
  • MSI = weighted average of recall scores across all cards in a topic, updated every session
  • Ebbinghaus forgetting curve modelled in real-time — R(t) = exp(−t/S)
  • Deterministic scheduler: zero random decisions. Every review is mathematically justified and auditable
  • 4-grade recall system: Again / Hard / Good / Easy — maps directly to SM-2 quality ratings
  • Full event log: every review is immutable, replayable, and auditable — the kind schools trust

Doubt Solver · Interactive NEW

Duolingo-Style
Doubt Resolution

Every student gets stuck. Most skip the concept, re-read passively (which doesn't work), or wait for a teacher. Rattafy's Doubt Solver changes all three. Type any doubt in natural language — get a five-step interactive resolution path: concept overview, visual SVG diagram, fill-in-the-blank, adaptive MCQ, and mastery check. Exactly like Duolingo, but for NEET, JEE, CBSE.

  • Natural language input — ask your doubt exactly as you'd ask a teacher
  • Auto-generated SVG diagrams for circuits, cell diagrams, reaction mechanisms, force diagrams
  • Progressive mastery: overview → flashcard → fill-blank → MCQ → mastery check
  • Adaptive difficulty: system detects struggle and adjusts explanation depth instantly
  • Every resolved doubt updates your MSI score for that concept in real-time
  • Exam-aligned: question style, vocabulary, and depth auto-tuned to NEET/JEE/CBSE/IIT JAM
  • Full KaTeX LaTeX rendering for equations, integrals, and chemistry formulae
  • Free-text follow-ups: ask as many follow-ups as needed in the same session

Learn Mode · Adaptive

Enter a concept.
Get a complete learning journey.

Not a search. Not a video. A structured, adaptive, mastery-driven experience — concept overview, bite-sized flashcards, fill-in-the-blanks, adaptive MCQs, and mastery check — all tuned to your level and exam target. Built like Duolingo but engineered for Indian academic content.

  • Type any concept from any subject: "Newton's Laws", "Meiosis", "Integration by Parts"
  • AI generates a personalised path based on your current MSI for that concept
  • Concept-first: clear overview calibrated to your level before any recall exercises
  • Active recall layers: flashcard → fill-blank → MCQ. Each step builds on the last
  • Adaptive difficulty: struggle on something? It comes back harder. Nail it? Unlock the next level
  • XP and streak tracking baked in — Duolingo-style engagement loop
  • Every journey updates your MSI, feeding the memory engine for future scheduling

The complete learning loop — inside every review session

Review Mode, Learn Mode, and Doubt Mode aren't separate apps. They're one seamless loop. Mid-session, tap Learn on any card to get a full adaptive lesson on that concept — without leaving your session. Tap Doubt to get an AI-generated explanation. Return to the exact card. Your session state is preserved throughout. This is the circular loop that makes Rattafy's retention so much higher than passive re-reading.

School Analytics · Live

Attendance tells you who showed up.
Rattafy tells you who's about to fail.

Every school runs on attendance and marks. Neither tells you what's happening inside a student's knowledge. Rattafy's analytics layer gives principals and teachers live efficiency metrics — per-student MSI scores, retention rates, at-risk prediction, and outcome dashboards. NEP 2020 compliant out of the box.

  • Per-student MSI scores by subject and chapter — visible to teachers and principals
  • At-risk student prediction before the exam — not after the results
  • School-vs-school benchmarking for principals managing multiple campuses
  • Fully auditable event log for every student session — NEP 2020 compliance ready
  • Teacher performance metrics: classes created, tests assigned, grading speed
  • Parent dashboard auto-populated from school data — no separate input required
