In plain words
Active Recall is a tool that summarizes online content and stores it in a knowledge graph, then resurfaces the material according to a personalized learning schedule designed to improve retention. It addresses the problem of forgetting most consumed information within a week by strategically timing reviews of key points. The software is designed for students and learners who want to retain and connect information across multiple sources.
