Overview

Spokabulary is a web-based tool that lets you create and play word games from your own vocabulary lists. You can choose from different game modes, such as Speak and Spell Challenge or Out of Order. Each game can be customized with AI to create tailored word lists that help students memorize vocabulary more effectively.

• Developed both the frontend and backend using Next.js, and optimized Unity-based games with WebGL to improve page load performance.
• Tuned multi-agent prompts and LLM chatbot behavior to adapt to different vocabulary levels and learning needs.

Impact

• Deployed an AI-powered gamified learning platform used by students to practice vocabulary with interactive 3D characters and conversational agents.
• From Oct 2024 to Jan 2025, the platform reached around 3,000 monthly active users.
