On every course
Courses work with a keyboard and on phones, tablets and desktops. Each can be read aloud with the spoken word highlighted, and diagrams carry written captions or text descriptions.
Course by course
Each course page lists that course's own accessibility features under “Accessibility and narration”, for example transcripts, adjustable speed, or the option to turn off motion.
