StudyBuddy — Your Personal AI Study Partner

StudyBuddy is an AI-powered study companion created for a friend who frequently studies from extensive notes and PDF documents. This tool aims to streamline the study process by integrating key features into one platform. The main functions of StudyBuddy are to Learn, Summarize, Practice, Ask questions, and Revisit the material.

Users can input their notes or upload a PDF, and StudyBuddy will process them to deliver results. It generates concise, structured summaries of the notes, creates multiple-choice quizzes based on the study material, and provides correct answers and explanations after a quiz attempt. The application also stores quiz history, allowing users to revisit earlier quizzes.

StudyBuddy goes beyond being a generic chatbot. It focuses on a practical study workflow that users can utilize while studying large quantities of material. The demo version can be accessed at https://hactober-dev-challenge1-1.onrender.com/.

The application's codebase consists of a React frontend and an Express/Node.js backend. The backend manages the API layer, AI integration, PDF text extraction, and MongoDB storage, while the frontend provides the user interface and study workspace. The project's infrastructure includes MongoDB Atlas for persistent storage, the Hugging Face Router for accessing open-weight AI models, and the OpenAI-compatible SDK for AI integration.

PDF text extraction is handled by the pdf-parse library, ensuring StudyBuddy can efficiently convert PDF documents into text for analysis. The core AI functionality relies on an open-weight model provided by Hugging Face via their OpenAI-compatible router, with the AI being the backbone of the application.
