  • In this user-friendly chrome extension, you can download the lecture videos in the course content you have already bought on Udemy collectively or individually.

  • If you turn off the "ask where to save before downloading" feature in Chrome settings, you can download in a categorized way. (You can change the settings on "chrome://settings/downloads")

Update notes : v3.1 - fixed stuck problem.
