Paste a link, press play, and let the video repeat — for practising an instrument, drilling a phrase in another language, learning choreography, or re-hearing an explanation. Everything runs in your browser on top of YouTube’s official embedded player: no account, no downloads, and no analytics or tracking of its own. Inside the player, YouTube’s own terms apply.
Mark A and B to repeat one passage, adjust the speed, save labelled loops, keep private per-video notes, or copy a share link containing only public playback state. Local labels and notes never enter the link.
