Voilaa! — Turning Any YouTube Video into an Interactive Learning App with Google Gemini

This post is my submission for DEV Education Track: Build Apps with Google AI Studio.

What I Built

Voilaa! is a full-stack educational playground that transforms any YouTube video into a rich, interactive learning experience — think live quizzes, flashcard decks, formula simulators, and data visualizations — all generated on-the-fly by Google Gemini AI.

The idea is simple: paste a YouTube URL, choose your academic depth, and within seconds Gemini analyzes the video's content and synthesizes a fully functional, self-contained interactive HTML learning app tailored to that exact lesson.
