Beyond

Beyond adds an "Open in Beyond" button under any YouTube video. About a minute later you get a page made for that video: a recipe becomes a step-by-step cook-along, a match a goal-by-goal replay, a song its parts, a review its verdicts, a lesson its key points and a quiz that jumps back to the exact moment. Long tutorials and lectures become full courses with a practice terminal, real Python in the browser and checked exercises. Videos play in YouTube's own player and every page credits the channel. Free to start.
