"The easiest way to take notes from videos. Everything synchronized!
"Have you ever been struggling to take notes while watching videos? Not anymore!
"VideoNotes, developed by UniShared (www.unishared.com), currently supports Youtube and Coursera videos and works best for the last versions of Chrome, Firefox, IE and Safari.
"It enables you to:
- Watch videos and take notes at the same time, on the same screen
- Keep the same shortcuts to play/pause your video while writing notes
- Automatically synchronize your notes and video. Just click on a line of your notes to jump to the related part of the video.
"Everything is automatically stored in your Google Drive, to access them everywhere."
