Brain Buddy – AI Educational Platform

Key Highlights

• Built an AI-powered educational platform featuring a voice assistant, GPT-4-generated personalised lessons, and adaptive exercises dynamically tailored to each student's learning progress and weak areas.
• Integrated OpenAI GPT-4 API for on-demand lesson generation — students describe a topic and difficulty level, and the system generates structured lessons with explanations, examples, and practice questions.
• Implemented a voice assistant using the Web Speech API for speech recognition and synthesis, enabling hands-free interaction for lesson navigation, Q&A sessions, and progress review.
• Designed an adaptive learning engine that tracks per-topic performance metrics, identifies knowledge gaps using spaced repetition principles, and adjusts exercise difficulty in real time.
• Built student and teacher dashboards: students track progress with visual analytics; teachers monitor class-wide performance, assign custom lesson plans, and view individual learning trajectories.
• Developed the frontend with Next.js for SEO-optimised, server-rendered lesson content and used MongoDB for flexible storage of user profiles, lesson history, and performance data.
