YouTube Looper
Loop any part of a YouTube video in your browser
YouTube Looper lets you repeat any section of a YouTube video instead of looping the whole thing. Paste a YouTube URL, set A and B points, adjust playback speed from 0.25x to 2x, and share the exact loop with a URL. It’s built for musicians learning riffs and songs, but it also works well for tutorials, dance practice, language learning, and any clip you want to replay without fighting the seek bar.
