Takes a lecture or talk recording of up to 120 minutes and returns study materia
Takes a lecture or talk recording of up to 120 minutes and returns study material: a summary, key terms, flashcards with front and back, and multiple-choice questions with four options, the correct answer and an explanation. Every card and question names the paragraph of the transcript it comes from, and the timestamp of that paragraph is attached so learners can jump to the place in the recording.
