Loop any section of a YouTube video. Paste a URL and set your A–B points.
No saved loops yet. Set A–B points and press Save.
YouTube's built-in controls let you replay an entire video, but there is no way to lock a specific section on repeat. An AB loop player solves this by letting you mark a start point (A) and an end point (B), then automatically looping only that segment — indefinitely and without interruption.
LearnLooper's AB loop player works entirely in your browser. Paste any public YouTube URL, set your A and B points with a single click, and the player handles the rest. No extension to install, no account required — just open the page and start looping.
