Repeat for YouTube™ A-B — HNE Looper
Extension Actions
Loop any YouTube segment with A-B repeat and counts (∞ or N). Clean popup UI, hotkeys, badge. Works on Shorts & YouTube Music.
A-B Repeat for YouTube™ — HNE Looper lets you loop any part of a YouTube video with precision. Set A (start) and B (end), choose Count (∞ or an exact number), and let it play—perfect for practicing music, language learning, tutorials, workouts, or revising lectures.
Why it’s great
Pinpoint loops: A-B repeat any segment to focus on the exact part you need.
Finite or infinite: Loop forever (∞) or exactly N times (e.g., 10).
Popup-only UI: No on-video overlay; nothing interferes with the player.
Hotkeys that play nice: Single-key controls on the YouTube page (R, [, ], ) don’t hijack Cmd/Ctrl+R reload.
Live badge: See R∞, R10, etc. right on the toolbar.
Works everywhere on YouTube: Watch, Shorts, and YouTube Music.
