01Company

A great teacher changes everything. Most learners never get one.

Every year, millions of Indians prepare for competitive exams. Most get a question bank, a timetable and a lot of guesswork, and rarely a teacher who knows exactly where they stand and what to do next.

Founded on 15 May 2026 by Ashish Kumar Sah, Eurobook exists to close that gap. We are an AI education company building technology that understands how each person learns (what they know, where marks leak, how fast they work) and turns it into clear, personal guidance every day.

We combine existing AI models with our own assessment, planning and learner-progress software. ExamRocket is the first product built on this work, and it is live today.

AI-based learning

Products that adapt to every learner. Study plans, practice and feedback are shaped by real performance, not a fixed chapter order.

Education, done seriously

Syllabus-aligned preparation for India’s major competitive exams, built for self-learners who study on a phone, in the language they think in.

New AI technologies

Applied research in tutoring models, document intelligence, memory and evaluation: the foundations of tomorrow’s learning tools.

02Flagship product

Meet ExamRocket. Our AI teacher, live today.

ExamRocket is Eurobook’s multi-exam preparation platform. Instead of leaving aspirants with a library of questions, it gives them one focused mission a day, and Maya AI rebuilds each mission around how they actually performed.

ExamRocketexamrocket.in · A Eurobook product
Live

An AI study assistant for structured preparation.

Maya uses available test results to help learners review performance, organise daily practice and ask study questions in English, Hindi or Hinglish. Important answers should be checked against reliable sources.

  • A personal daily mission across a 69-day roadmap
  • A real CBT simulator with negative marking and an English/Hindi toggle
  • Previous-year papers, mock tests and adaptive topic drills
  • A Mistake Book that turns every error into scheduled revision

How the learning loop works

Record: a submitted attempt supplies answers, score and timing information.

Plan: Eurobook’s rules combine topic priorities, exam settings and study time to select available practice and revision.

Explain: Maya receives the question, conversation and available study context to generate an explanation through Bedrock.

Check: AI answers can be wrong. Learners can report issues; a stored solution passing source and format checks is not a guarantee of correctness.

How Maya AI works

One loop, repeated every day of the mission. Study today, let Maya AI learn from it, and start tomorrow with a plan built for you.

  1. 01

    Study today

    Finish today’s plan: subject practice blocks, mistake review and quick recall.

  2. 02

    Maya AI analyses

    It reads accuracy, speed and weak areas from the work the learner actually did.

  3. 03

    Tomorrow’s plan unlocks

    The next day is rebuilt around whatever slowed the learner down. Miss a day, and the plan adapts instead of breaking.

Four commitments behind every product decision at Eurobook.

  • Learning comes first

    Learner data is used to personalise learning and run the service. We don’t sell personal data, and it is encrypted in transit.

  • Built for Bharat

    Mobile-first, bilingual and free to start, designed for self-learners in every part of India.
