Comment Chapters for YouTube™

Timestamped comments are a gift. "1:24 chorus starts here" "8:02 the bit I love" — someone took the time to write it down, so you can go straight to the part you wanted. Now imagine using them as actual chapters. This extension rebuilds that comment into a chapter list with thumbnails and puts it beside the video, highlighting the chapter you are in as it plays. If the description already lists timestamps, those become chapters too — ready the moment you open the video, with nothing to click. ■ What it does ・Turns a timestamped comment into a chapter list in one click ・Builds chapters from the video description too, ready the moment you open it ・Switch between description and comment above the list ・Shows a thumbnail of the moment on every row ・Follows playback and highlights the chapter you are in ・Click a row to jump to that time ・Show the list inside the page, pop it out into a Picture-in-Picture window, 　or fold it down to a small card ・In the Picture-in-Picture window the video plays alongside the list: show both, 　just the chapters, or just the video (side by side when the window is wide) ・Play/pause, chapter skip, volume and playback speed live in the list ・Hold the play or speed button for temporary 2x while you hold it ・Drag it anywhere and resize it. It remembers where you put it ・Every comment you open is kept in a history, reachable from the toolbar icon 　(thumbnail, comment, video title, channel, how long ago) ・Bookmark history entries to keep them (up to 5) ・Available in 10 languages ■ How to use it 1. Find a timestamped comment on a YouTube video page 2. Click "Show as chapters" on that comment 3. The chapter list appears beside the video * When the description has timestamps, the same link appears under the view count. ■ What is stored The comment you opened and details of that video are stored on your device. If you are signed in to Chrome, they sync between your own devices. Nothing is sent to any server of ours. Nothing is sold or shared. You can delete everything from the toolbar icon at any time.
