A-B Loop — Video Repeat

About

A-B Loop repeats a section of any video, over and over. Set an A point and a B point on the timeline and the video loops that exact segment endlessly — perfect for practising a guitar riff, re-listening to a phrase in a language, drilling a dance move, or reviewing one part of a lecture.

Open a page with a video, set A and B, done. No account, no sign-up, nothing to configure.

🔁 LOOP ANY VIDEO SEGMENT
• Click Set A where the segment starts and Set B where it ends — the video instantly repeats just that part, on a smooth loop.
• Optional repeat limit: loop a fixed number of times (say 5) and then stop, or leave it on ∞ to loop forever.
• Clear it in one click to go back to normal playback.

🎬 WORKS ON THE VIDEOS YOU ACTUALLY WATCH
• YouTube, Vimeo, online course and lecture players, music sites, and any page with a standard HTML5 <video> element.
• Picks the video you're actually watching — even if several are on the page.
• Built on the browser's native video controls, so it's fast and reliable and doesn't break when sites change their layout.

💾 SAVE LOOPS AND COME BACK
• Name and save a loop (for example "Chorus" or "Solo") and it's remembered for that website.
• Reopen the page later and re-apply a saved loop with one click.

🔒 100% LOCAL & PRIVATE
• Everything runs on your device. No servers, no account, no network requests, no data collection.
• Your loop points and saved loops stay in your browser and never leave it.
• No ads, no tracking.

🔑 MINIMAL PERMISSIONS
• Uses only activeTab + scripting, and only for the page you're on — no host permissions, so it doesn't run on pages in the background. storage is used only to remember your saved loops.

A-B Loop is a playback tool: it only changes where a video you're already watching is playing from, exactly like dragging the progress bar back yourself. It does not download, record, or copy video.

Free, no ads, no tracking.
