SuperMemo is a software program designed to help users learn and retain information more effectively. It uses a technique called spaced repetition, which schedules review sessions based on how well a user remembers specific information. This method optimizes learning by ensuring that material is revisited just before it is likely to be forgotten. Originally developed by Piotr Wozniak in the late 1980s, SuperMemo has evolved over the years and now includes various features such as multimedia support and customizable learning paths. It is widely used by students, language learners, and professionals seeking to enhance their knowledge retention.
