CourseSpeed controls only the video playback interface — the same as adjusting your TV settings. It does not bypass DRM, access protected content, or interact with platform authentication. Q: Why premium? A: Free features cover all core playback controls. Premium unlocks advanced learning efficiency tools and supports ongoing development. Q: Does 1.5x speed really not hurt learning? A: It's the most studied question in educational video research. 24 independent studies confirm: comprehension at 1.5x equals 1x, and learner satisfaction is actually higher at 1.5x.
