boltQuiz

💡 Inspiration

As an instructor, managing quizzes, grading, and providing meaningful feedback can be incredibly time-consuming and repetitive. I needed a solution that would streamline this process—enabling quick, high-quality quiz creation and automatic evaluation using AI. That’s how boltQuiz was born.

⚙️ What It Does

boltQuiz empowers educators to:

• ✨ Instantly generate quizzes using OpenAI, from a simple topic or prompt

• 🧑‍🎓 Allow students to take quizzes through:

  • 📝 Form Mode
  • 💬 Chatbot Mode
  • 🎙️ Voice Mode (powered by ElevenLabs)
  • 📹 (Coming Soon) Video Avatar Mode via Tavus

• 🤖 Automatically evaluate responses using OpenAI — considering accuracy, response time, and generating personalized feedback

• (Future) 📊 Monitor performance in real-time with an intuitive dashboard

🛠️ How We Built It

• Frontend & Backend: Built using Next.js 14
• Database: PostgreSQL
• AI Integrations:
  • 🤖 OpenAI API – for quiz generation and intelligent evaluation
  • 🔊 ElevenLabs API – for voice synthesis and speech recognition Note Try to use Tavus but not success.

🚧 Challenges We Ran Into

• Hosting and connecting to the PostgreSQL database
• API integration setup and authentication
• Difficulty integrating Tavus video avatars
• Managing real-time, multi-modal quiz delivery (especially voice) with low latency
• Designing fair evaluation for open-ended responses with personalized suggestions
• Still have trouble with Evaluating quiz with Generative AI to make it precise.
