The Challenge
Bharat Minds AI, an edtech platform, needed to generate thousands of high-quality exam questions from textbook content across multiple subjects and difficulty levels. Manual creation was taking their content team 3-4 weeks per subject.
Our Approach
Phase 1: Content Extraction
We built an intelligent document processing pipeline using OCR (Tesseract + custom models) and NLP to extract structured content from textbook PDFs, including diagrams, tables, and mathematical equations.
Phase 2: Question Generation
Using fine-tuned LLMs with curriculum-aligned prompts, we built a system that generates questions with:
Phase 3: Quality Assurance
An AI-powered QA layer checks for factual accuracy, difficulty calibration, and curriculum alignment before human review.
Results
Key Takeaways
The project is now in production, powering question banks across 12 subjects for competitive exam preparation.
