Start with a goal in plain language and a few sentences on what you know. Strive's AI asks a questionnaire written for that goal, then designs the curriculum — modules, lessons, quizzes — which you refine by chatting with it. Each lesson is written the moment you open it and streams in block by block: explanation, code, diagrams, inline checks. Module quizzes test synthesis across lessons; every lesson seeds recall cards returning at 1, 3, 7, 14, 30 days. Free to start, no credit card.
