About this extension
This extension uses the Sudachi lexical analyzer and the Mozilla Readability.js library to identify the main content of any page and, when the extension is activated, all Japanese text in the main content will be parsed and highlighted. Words matching known dictionary entries or grammar rules (currently JLPT N4/N5/N3 is supported) are underlined in blue. Hovering over words will let you view definitions, part of speech categories, and grammar explanations.
