Youtube Chapter Progress is a free Chrome extension developed by DInteractive. This extension modifies the Youtube video page by adding a progress bar under the active chapter in the Chapters list. The progress bar displays the time remaining in that chapter, allowing users to easily track their progress within the video.

With Youtube Chapter Progress, you not only have a visual representation of the overall progress of the video, but also the ability to see how much time is left in each chapter. This feature is particularly useful for longer videos with multiple chapters, as it helps you navigate and jump to specific sections more efficiently.

Additionally, the extension offers the option to display a permanent progress bar beneath the main video player. This bar remains visible even when you're not interacting with the video player, providing a constant visual reference of your progress.

Customization options are available, allowing you to adjust the visibility of the progress bars. You can choose to display the chapter bar only when hovering over the active chapter by clicking on the extension icon.

Please note that the progress bars added by Youtube Chapter Progress are not interactive. They solely serve the purpose of displaying the progress of the video and the chapter independently.
