This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built I built Study Buddy, a personalized AI study assistant for my brother who usually understand stuff easily but forgets it quite quickly.

This submission for the Hacktoberfest Weekend Challenge is a personalized AI study assistant named Study Buddy. The creator built it for his brother, who often understands new information but struggles to retain it. Instead of having the user reread extensive notes, Study Buddy provides a concise overview of study material and can create a short quiz to test understanding. Key features include:
- Simplified explanations of complex concepts
- Analogies to help explain concepts using real-world examples
- Concise exam-ready answers
- Generated quizzes to assess comprehension
The app utilizes Gemma 4, an open-weight model accessed via the Gemini API. To run the project, users need to install Node.js, clone/download the code, set up a .env file with their Google AI Studio API key, and start the server. The frontend is built using HTML, CSS, and JavaScript.
Study Buddy was designed with open innovation in mind. By using an open-weight model instead of a closed proprietary one, the creator gained greater transparency and adaptability in the AI foundation. The intentionally small MVP scope focuses on the core learning loop: student notes → personal question → personalized response. The AI receives the study material, question, and learning mode, and generates appropriate responses based on the provided instructions.
The project emphasizes using open models to create personalized applications tailored to individual needs, rather than relying on black-box features from closed platforms.
