Study Loop - YouTube Learning Loop Tool

Efficiently review YouTube video sections with AB loop. Track mastery and visualize study progress.

━ What is Study Loop? ━ Study Loop is a Chrome extension that lets you select any segment of a YouTube video to repeat in a loop — perfect for mastering difficult content. Whether you're studying for a certification exam, improving your language skills, or learning a new skill from video courses, Study Loop keeps you focused on what matters. ━ Key Features ━ [AB Loop Playback] Set a start point (A) and end point (B) on any YouTube video to loop that segment repeatedly. Use keyboard shortcuts (A / B / L) for fast, seamless control. [Segment Saving & Management] Save difficult segments with custom names and tags (up to 5 segments in the free version). View all saved segments in the side panel — click any segment to jump to it and start looping. Track mastery with three levels: Unlearned → Learning → Mastered. [Loop Interval] Automatically pause after reaching point B, display a countdown, then resume from point A. Gives you built-in thinking time to recall what you just heard before the next repetition. [Courses & Folders] Organize videos into courses by topic (e.g., one course per exam or subject). Use folders within courses for further categorization. [Study Statistics & Calendar] A monthly calendar shows your daily study activity at a glance. Track total study time, mastery rate, and consecutive study days. [Badges] Earn achievement badges as you reach learning milestones. Stay motivated. [Color Themes] Choose from Dark, Light, or Natural themes to match your preference.
