Youtube Quiz Generator

Pauses YouTube videos at intervals and shows AI-generated multiple-choice quizzes about what you have watched so far.

Turn passive watching into active learning. YouTube Quiz Generator automatically pauses YouTube videos at set intervals and challenges you with AI-generated multiple-choice questions — based on exactly what you've watched so far. Whether you're studying a lecture, following a tutorial, or simply trying to retain more from the videos you watch, this extension keeps your brain engaged by turning any YouTube video into an interactive learning session. HOW IT WORKS At a configurable interval (e.g. every 5 minutes of watch time), the extension pauses the video and presents a short quiz. Every question is generated from the video's actual transcript — covering only the content you've already seen, never spoiling what's ahead. Answer the questions, see instant feedback, then continue watching. Questions are quietly generated in the background before each quiz is due, so the dialog appears the moment the video pauses — no waiting, no loading spinners. WHY YOU SHOULD USE IT Research on learning consistently shows that active recall — being tested on material shortly after encountering it — dramatically improves long-term retention compared to passive re-watching or note-taking alone. This is sometimes called the "testing effect." YouTube Quiz Generator puts this into practice automatically. You don't need to prepare flashcards, pause and write notes, or find a separate quiz tool. Just install the extension, add your API key, and every YouTube video becomes a self-testing session.
