I Built StudyBuddy AI: An Open-Source Study Assistant for Students Using Ollama and Llama 3

A developer built StudyBuddy AI, an open-source study assistant that turns student lecture notes into summaries, quizzes, flashcards, and personalized study plans. The application runs locally using Ollama and the Llama 3 model behind a Streamlit interface, keeping processing on-device for privacy. A classmate responded, "I wish I had this before my last exam.

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend https://dev.to/challenges/hacktoberfest-weekend-2026-10-01 . I built StudyBuddy AI , an AI-powered study assistant designed for students like me and my classmates. A friend mentioned that preparing for exams often takes longer than studying itself. Students spend hours creating summaries, flashcards, and quizzes from lecture notes. To solve that problem, I created StudyBuddy AI. The application transforms notes into: using open-source AI running locally. https://symmetrical-waddle-7j79j569w74364g-8501.app.github.dev/ https://symmetrical-waddle-7j79j569w74364g-8501.app.github.dev/ https://github.com/psanogo/studybuddy-ai https://github.com/psanogo/studybuddy-ai ✅ Note Summarization ✅ Quiz Generation ✅ Flashcard Creation ✅ Personalized Study Plans ✅ Local AI Processing with Ollama ✅ Student-Friendly Interface Repository: Student Notes ↓ Streamlit UI ↓ Ollama ↓ Llama 3 ↓ Summaries | Quizzes | Flashcards | Study Plans The application uses Ollama to run open-source AI models locally while Streamlit provides an easy-to-use interface for students. Open innovation made this project possible. Using open-source AI allows: Because the models are open, anyone can improve, customize, and learn from the technology. For students, that means accessible AI-powered learning tools. Building StudyBuddy AI helped me learn: Most importantly, I learned that a small project can create meaningful impact when it solves a real problem. After seeing the project, one classmate said: "I wish I had this before my last exam." That feedback confirmed that this project addresses a real student need. StudyBuddy AI was built to help fellow students spend less time preparing study materials and more time learning. It uses open-source AI at its core, runs locally with Ollama, protects user privacy, and solves a real educational challenge. Thank you for reading
