A: Yes. YouTube AI tools cannot access DRM-protected course content on Udemy, Coursera, or LinkedIn Learning. CourseSpeed can — because it captures audio locally while you watch, then transcribes. Q: Does this download or record courses? A: No. CourseSpeed controls video playback speed and captures audio for AI note generation only. It cannot and will not download, record, or redistribute course videos. Audio is discarded immediately after transcription. Q: Is this allowed by learning platforms? A: Yes. CourseSpeed interacts only with the video playback interface, similar to adjusting volume or playback speed in any video player. It does not bypass DRM, access protected content, or interfere with platform authentication. Q: Why another speed controller when there are free ones? A: Most generic speed controllers forget your settings (a widely reported bug), lack AI note-taking, and aren't optimized for course platforms. CourseSpeed was built because the developer personally lost hours of study notes when a generic speed controller's shortcuts reset mid-lecture.
