WICS is a Chrome extension developed by gorbitgames. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. With WICS, users can add and manage custom items for WaniKani, a popular spaced repetition system for learning Japanese kanji and vocabulary.

This extension enables users to leverage the power of the WaniKani SRS (Spaced Repetition System) for their own items. Whether you want to reinforce your knowledge of specific kanji or expand your vocabulary beyond the pre-existing content in WaniKani, WICS provides the flexibility and control to do so.

WICS is available for free, making it accessible to all WaniKani users who want to enhance their learning experience. If you're looking to customize your WaniKani experience and take your Japanese language learning to the next level, WICS is a valuable tool to consider.
