About this extension
Rikaitan transforms your web browser into a tool for cultivating Japanese language proficiency, enabling you to make sense of texts which could otherwise be too hard to comprehend. This extension is akin to 10ten Japanese Reader for Firefox and Rikaikun for Chrome, however, it's distinct in its aspiration to be a comprehensive studying aid in contrast to a simple browser dictionary.

After installing Rikaitan, please read the manual to better understand how to use the add-on.
