Nuros

Nuros is an AI study app for students preparing for AP exams, the SAT and college work. Upload a PDF, paste a YouTube lecture or name a topic, and it writes structured notes built around concepts. It then generates quizzes, flashcards and full length timed mock exams from your own material, grades them with explanations, and tracks mastery concept by concept. ARC, the adaptive review cycle, resurfaces what you keep getting wrong until it sticks. Web, iOS and Android, with a free tier.
