WaniKani is a web application that helps people learn Japanese kanji and associated vocabulary. It uses radicals, mnemonics, and a spaced repetition learning system in order to help its users memorize the characters and vocabulary more effectively. The name "WaniKani" is a combination of the Japanese words for alligator (wani) and crab (kani). [2] WaniKani entered beta on May 14, 2012.[3] It moved out of beta on Sept 8, 2015.[4] Initially it had 50 levels, in June 2015 levels 51-60 were added. The first three levels are free.[5]
