Brainscape is a mobile learning platform that uses spaced repetition to help users learn new information more quickly based on cognitive science principles. Users can create their own flashcards or use pre-made content on various topics. When reviewing flashcards, users self-assess how well they remember the information, which helps strengthen memory retrieval before the next review. This spaced repetition combined with self-assessment is designed to optimize the intervals at which information is repeated to best aid long-term retention. Brainscape offers both a platform to collaboratively create flashcards and a marketplace of expert-created content on diverse subjects.
