I Got Distracted Watching a Golang Tutorial. So I Built an Project That Won't Let You.

A developer, distracted while watching a Golang tutorial on YouTube, built LingoLearn for the Lingo.dev hackathon — a tool that turns passive YouTube video watching into active learning by generating quizzes at key moments. The app uses Next.js App Router, Groq for LLM-based quiz generation, and the Lingo.dev SDK for translation into 130+ languages, targeting ~800 million non-native English speakers who consume English YouTube content daily.
