Narrated chalkboard
A teacher writes each step by hand and explains it aloud in a natural studio voice, synced to the writing.
Drop in notes, a PDF, or a photo. ReasonBoard writes the lesson out by hand on a chalkboard and teaches it aloud — step by step, with quizzes and a “raise your hand” button, in 13 languages. A teacher checks every lesson before the class sees it, and once it’s downloaded it plays with no connection at all.
