I built LearnTube AI, a Chrome extension that transforms passive YouTube watching into active learning. It automatically generates AI-powered quizzes during videos, like Coursera’s quiz system — but works on any YouTube video.
It analyzes transcripts, pauses at natural breakpoints, and asks contextual questions to help you retain more. Works fully client-side using Chrome’s built-in Gemini Nano AI for privacy, or optionally via the Gemini API for faster, cloud-based processing.
Key features:
– Auto transcript parsing and quiz generation for any captioned video
– Mid-video and end-of-video quizzes with explanations
– Works offline (on-device mode) or via Gemini API (faster mode)
– Visual quiz markers on the seekbar
– Popup dashboard for managing models, API keys, and progress
Built to make learning from YouTube as focused and interactive as formal platforms like Coursera — but with zero setup for creators.
