This extension uses the Sudachi lexical analyzer (WASM build via https://github.com/Benjas333/sudachi-wasm333) and the Mozilla readability library (https://github.com/mozilla/readability) 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 grammar rules (currently JLPT N4/N5 is supported) are underlined in blue, and other matched words in the included JMDICT dictionary are underlined in green. Hovering over words will let you view definitions, part of speech categories, grammar explanations, and links to external sites for learning more.
