You'll never miss a Japanese lesson on WaniKani again when you have this handy extension. The WaniKani Notifier sends you alerts when you have more materials to study on the Japanese kanji-and-vocabulary-learning web app.

The extension updates a badge on its icon when you have more things to study. Another convenient feature of this tool is that you only need to hover your cursor on the extension icon to see the time of your next review. It can also send you a desktop notification if you want.

If you want to go to the WaniKani website, simply click the extension's icon on the tool bar of your browser. The tool also syncs itself with Chrome Sync to automatically set your Chrome browsers.
