Final Guardian

Inspiration

I wanted to create a tool that genuinely helps students prepare for exams—something more intelligent than flashcards and more engaging than passively reading notes. I asked: what if students could upload their lecture slides, class notes, or key summaries, and instantly generate interactive quizzes, get AI-based evaluations, and even chat with a tutor trained on their own content?
That’s how FinalGuardian came to life.

What it does

FinalGuardian is an AI-powered exam preparation assistant. It allows students to:

Upload their own notes or lecture slides
Automatically generate topic-based quizzes
Submit answers and receive feedback with explanations
Chat with an AI tutor that can answer questions based on their uploaded materials

How we built it

Frontend: Built with Streamlit for quick iteration and responsive design
Backend: FastAPI manages APIs for quiz generation, evaluation, and conversation
Embeddings: Azure embeddings + ChromaDB for semantic search
LLM Integration: Azure OpenAI (GPT-4) for generating quiz questions and providing explanations
LangChain: Used to integrate tool-based retrieval and agent flows
Deployment: Streamlit Community Cloud (frontend) + Render (backend)

Challenges we ran into

Due to token limits in Azure OpenAI, I had to trim input documents and optimize prompt length. I also had to abandon memory support in the conversational agent to stay within token budgets.
In addition, rate limiting and other API issues led to various failures that required robust error handling.

Accomplishments that we're proud of

As an AI beginner, I gained hands-on experience with real-world AI application techniques
Designed and implemented a complete educational tool in a short time
Integrated LangChain's agent and retriever system with real use cases
Managed to connect user-generated content with LLMs in a seamless pipeline
