§ THE PREPARATION OS · LIVE
You study the syllabus. Thozha studies you.
Thozha is the first preparation platform that actively studies the aspirant - predicting what you'll forget, naming why you missed a question, and rebuilding tomorrow's plan around what's actually slipping.

§ THE PROBLEM
You can't fix what no one is measuring.
Most aspirants follow a static plan, forget half of what they study, and repeat the same kind of mistake for months without realising it. Generic AI apps don't fix this - they just hand you more content.

§ THE PREPARATION OS
Six intelligence engines, running in the background.
Every lesson you read, every MCQ you attempt, every Mains script you upload feeds a system that's actively modelling your memory, your mistakes, and your trajectory to exam day.
§ THE INTELLIGENCE LAYER
Outcomes the OS owns for you.
Each engine is live in production today. They share data, so a forgetting alert today changes tomorrow's strategist plan automatically.
LIVE
Forgetting Engine
Predicts what you’ll forget - before you forget it.
LIVE
Readiness Index
One number that knows your real exam-day score.
LIVE
AI Study Strategist
Today’s plan, rebuilt overnight from yesterday’s data.
LIVE
Mistake Intelligence
Learn why you got a question wrong - not just that you got it wrong.
LIVE
Trajectory Predictor
Where today’s pace puts you on exam day - and what shifts the line.
§ HOW IT FITS TOGETHER
The OS analyses. The Sandbox is where you actually work.
Two layers, one product. The OS watches everything that happens inside the Sandbox - and writes tomorrow's plan because of it.
§ THE BRAINALWAYS RUNNING

§ DEEP DIVE · 01
Stop forgetting concepts you already studied.
The Forgetting Engine watches your retention curve per concept and surfaces items before they slip below 60%. The next morning, those same items show up at the top of your revision queue - without you asking.
- Per-concept retention from your spaced-repetition history
- Auto-tags items below 60% retention as 'at risk'
- Pre-loads tomorrow's revision queue with the right items
- Updates hourly · live, not weekly

§ DEEP DIVE · 02
Stop the pattern, not just the question.
When you miss an MCQ, Thozha asks why in one tap - Qualifier Trap, Factual Gap, Conceptual Gap, or Silly Mistake. Aggregated weekly, it tells you the actual shape of your weakness.
- One-tap categorisation right after a wrong answer
- Weekly aggregate with the dominant category highlighted
- Concrete prose insight, not just bars
- Resets every 90 days so old patterns don't bias today
§ DEEP DIVE · 03
See exam day from where you are today.
The Trajectory Predictor draws your current readiness against Safe / Borderline / Risk zones, then projects where today's pace lands you. Add 30 minutes a day and watch the dashed line shift before you commit.
- Today vs exam day at a glance
- Safe / Borderline / Risk zones drawn from cohort data
- Run scenarios - see the line move before you change your routine
- Updated weekly from your readiness snapshots

§ VOICES
Aspirants the OS is studying right now.
3,200+ active aspirants
“The forgetting alerts caught Article 32 retention dropping three days before I'd have noticed myself. That single feature is worth the SUPER cost.”
Aditya R.
Mains 2025 · Delhi
“Mistake Intelligence showed me 60% of my GS-2 misses were qualifier traps. I had no idea. One week of slowing down on those words and my prelims mocks jumped.”
Ramya K.
UPSC 2027 · Coimbatore
“The trajectory chart told me I'd land at 68% if nothing changed. I added 30 minutes a day. Three weeks later the projection moved to 79%. No other app shows you this.”

§ COMMON QUESTIONS
Before you start.
Don't see your question? Write to the support desk →
Every lesson, MCQ and Mains script you put through Thozha feeds a per-user model: subject ELOs, fatigue patterns, retention decays per concept, and mistake categories. That model is the Digital Twin. Every other engine - the Forgetting alerts, the Strategist, the Trajectory chart - reads from it.
No. Your study data is encrypted at rest, isolated to your account via row-level security in Supabase, and never shared with model vendors. See our Privacy Policy.
Most apps run AI on a question - give it a prompt, get an answer. Thozha runs intelligence on you: predicting forgetting, naming mistake patterns, projecting your exam-day score. The AI tutor is the smallest part of the product.
It's a projection from your weekly readiness trend - directional, not a guarantee. It updates every Sunday and shifts as your behaviour shifts. We'd rather show you the line and let you adjust than promise an outcome.
Free runs the Sandbox (lessons, MCQs, basic insights). SUPER runs the complete Preparation OS - real-time twin updates, unlimited Forgetting alerts, live Readiness and Trajectory, and unlimited Mains/AI usage. You can try SUPER for 7 days for just ₹7.
The mobile app caches lessons, mind-maps and saved MCQ sets in SQLite, so the Sandbox works offline. The OS engines need network for live recompute - they catch up automatically when you reconnect.
