A personalized learning platform that employs Retrieval-Augmented Generation (RAG) to enable students to interact with their study materials through an AI-powered assistant. The system comprises a web-based interface built with React that allows users to upload educational documents in various formats including PDF, DOCX, TXT, and YouTube video transcripts, which are then processed through a text extraction and chunking pipeline. Document chunks are encoded into 768-dimensional vector embeddings using the all-mpnet-base-v2 sentence transformer and stored in a Pinecone vector database for efficient semantic retrieval. When users pose questions, the system retrieves relevant passages from their uploaded documents and conditions a language model's response generation on this retrieved context, ensuring factually grounded and document-specific answers. The platform includes eight integrated learning modes: interactive chat-based question answering, automated quiz generation, AI-scored mock tests, virtual interview sessions, a swipeable flashcard feed (Doomscroll), per-page PDF analysis with graded questions, in-browser PDF annotation with AI-powered Q&A on highlighted text, and rich note-taking. The backend implements a FastAPI server with asynchronous HTTP endpoints, JWT-based authentication, and hybrid data persistence using MongoDB and Pinecone. The system is designed to improve learning outcomes through retrieval augmentation, reduce hallucination compared to ungrounded language models, and support concurrent users with low-latency responses, thereby democratizing personalized tutoring for students regardless of geographical or economic constraints.
