Smart.fm (formerly iKnow!) was a social learning- and community website created by Cerego Japan, Inc. The website used spaced repetition algorithms (SRS) to assist users in committing facts to long term memory and increasing learning speed. Users could create, manage and share lists of facts to memorize; as well as learn a number of languages. Progress could be monitored with tests. The data was used to automatically plan a curriculum and learning strategy for the users.In addition to the website base, Smart.fm also had a Facebook application.
