Doubtbuddy, an IndianMinistry of Education–funded initiative, has set out to tackle one of education’s toughest challenges, helping students prepare for high-stakes exams like JEE Advanced and Gaokao. Traditional learning tools fail to offer deep, contextual guidance on complex problems. In response, Doubtbuddy developed an AI doubt solver that delivers detailed, step-by-step explanations using advanced GenAI techniques.

The result: an intelligent learning copilot capable of understanding student queries, breaking down complex concepts, simulating expert-level reasoning, transforming how students learn and prepare.

About Doubt Buddy

Doubt Buddy is one of India’s leading education companies for students of classes 6 to 12 and engineering and medical entrance exam aspirants, Doubt Buddy provides students with personalized practice, mock tests, previous year question papers, and live doubt resolution which help students learn better and faster. Doubt Buddy covers the syllabus for all school boards across India for Class 6 to 12.

The problem: complex doubts, slow explanations, and limited expert access

Students preparing for competitive exams often struggle with intricate problems that require more than just final answers; they need clear, step-by-step reasoning. Traditional tutoring, forums, and learning apps often fall short, offering vague or incomplete explanations. Students waste valuable time waiting for responses or attempting to decipher unclear solutions, weakening their understanding of the material.

Doubtbuddy identified the need for a scalable, intelligent AI doubt solver, one that could not only solve problems but also teach the method behind the solution.

The solution: an AI doubt solver with explainable intelligence

To bridge the gap between expert-level tutoring and scalable access, Doubtbuddy built a conversational AI doubt solver fine-tuned to handle exam-level academic complexity.

Expert-Level, Step-by-Step Problem Solving

Built on a decision tree-based Llama-3 8B model, fine-tuned on 3 million advanced problems curated by global educators. The system simulates how a seasoned teacher would approach, deconstruct, and solve complex academic queries.

Natural Language Understanding for Diverse Student Inputs

Students can submit queries in natural language or through problem images. The AI doubt solver processes these and responds with structured, multi-step explanations rather than just the final answer.

Always Learning, Always Improving

A feedback loop continuously retrains the model using student feedback, improving accuracy and relevance over time.

The impact: smarter prep, stronger understanding

DoubtBuddy’s AI doubt solver isn’t just another edtech app, it’s a personalized learning copilot.

• 95% accuracy on JEE and Gaokao-level questions
