  Live Quiz

Inspiration

Creating quality quizzes manually is tedious, while live quiz platforms often lack intelligent content generation. I wanted to combine AI with real-time multiplayer interactions to build a platform that can generate engaging quizzes instantly and make learning more interactive.

What it does

IntelliQuiz is an AI-powered real-time quiz platform where users can generate quizzes from natural language prompts, configure difficulty and question count, and host live multiplayer sessions. Participants can join using a room code and compete through synchronized timers and dynamic leaderboards.

How I built it

I built IntelliQuiz using Next.js, TypeScript, Tailwind CSS, and shadcn/ui for the frontend, with PostgreSQL and Prisma ORM for data management. Socket.IO powers the real-time quiz experience, while Redis Sorted Sets handle low-latency leaderboard updates. GROQ API is used for AI-based quiz generation.

Challenges I ran into

The biggest challenge was designing a smooth real-time architecture with synchronized timers and instant leaderboard updates. Managing AI API rate limits and planning a scalable approach for future PDF-based quiz generation also required careful system design decisions.

Accomplishments that I'm proud of

I'm proud of building a complete end-to-end AI quiz platform that combines AI-generated content with real-time multiplayer gameplay. Integrating WebSockets and Redis for live interactions with low latency while maintaining a clean and responsive user experience was a particularly rewarding achievement.

What I learned

This project helped me gain practical experience with WebSocket architectures, Redis-based real-time state management, and integrating LLM APIs into production workflows. I also learned how to balance scalability, performance, and user experience.

What's next for IntelliQuiz

I plan to extend IntelliQuiz by supporting PDF and YouTube-based quiz generation, AI-generated answer explanations, personalized learning insights, and improved real-time infrastructure to support larger live events and classrooms.
