Doubtbuddy
AI-Powered Doubt Solving Platform
Transforming Student Learning with AI-Driven Doubt Solving
Algofolks helped Doubtbuddy build a multi-modal AI platform across web and mobile, enabling instant doubt solving, faster responses, and 24×7 intelligent support for students.
Client Overview
Doubtbuddy is an education technology platform focused on helping students get instant help with academic doubts. The product targets school and test-prep learners who need quick, accurate explanations across subjects like Mathematics, Physics, Chemistry, and more.
They wanted to move from a basic Q&A concept to a smart, AI-first learning assistant that:
- Understands text, image, and handwritten questions
- Provides detailed, stepwise explanations
- Works smoothly across web and mobile apps
- Scales reliably during exam peaks
The Challenge
Before engaging Algofolks, Doubtbuddy faced several limitations:
Before: Manual & Slow
- No robust flow for image-based and handwritten questions
- Existing architecture could not scale reliably during high-traffic exam seasons
- The mobile experience was basic, causing student drop-offs
- No intelligent way to personalize learning paths or suggest related questions
After: AI-Powered & Scalable
- Instant AI-powered responses in seconds
- Multi-modal support for text, images, and handwriting
- Scalable infrastructure handling exam peaks
- Polished mobile-first experience
- Intelligent personalization and recommendations
They needed a full-stack upgrade: AI engine, backend orchestration, and a high-quality mobile experience.
Our Approach
We followed a structured plan to convert Doubtbuddy's idea into a scalable product.
Journey & Requirements Mapping
