How Quiz Crafter Works

Tech Stack Overview

- Frontend: Built with React, providing a clean and responsive interface for quiz creation, question display, and result summaries.

- Backend: Developed using Flask, handling API requests, quiz logic, and AI processing.

- AI Engine: Powered by LangChain and integrated with Gemini or OpenAI’s GPT-4 for natural language understanding and question generation.

Workflow

1. Input Collection:

- The user selects quiz preferences or uploads a document.

- The React frontend sends these inputs to the Flask backend.

2. AI-Driven Question Generation:

- Using LangChain, the backend processes the data and generates questions tailored to the subject and topic.

- For PDFs, LangChain’s document loaders extract text, splitting it into manageable chunks for analysis.

3. Quiz Rendering:

- The generated questions are sent to the React frontend, where they are displayed in an interactive quiz interface.

4. Result Evaluation:

- User responses are sent back to the backend for validation.

- The AI checks answers against a predefined set or uses LLMs to verify correctness dynamically.

Challenges and Solutions

1. Generating Quality Questions

Challenge: Ensuring the questions are relevant, grammatically accurate, and suited to the user’s needs.

Solution: Advanced prompt engineering within LangChain helped refine the LLM outputs for accuracy and variety.

2. Processing Large PDFs

Challenge: Parsing and processing extensive documents without delays.

Solution: The use of LangChain’s RecursiveCharacterTextSplitter allowed for efficient chunking and analysis.

3. Real-Time Responsiveness

Challenge: Maintaining speed and responsiveness while handling AI computations.

Solution: Flask handled API calls efficiently, while React ensured the frontend remained smooth and interactive.

Behind the Scenes: Pages That Make it Work
