This browser extension allows quick translations from Japanese directly in your browser. By selecting text on a web page, the extension shows the translation in a discreet overcard above the selection. It also offers the ability to view the Romanji transliteration of Japanese and easily switch between translation and Romanji.
With automatic language management, cache for performance improvement, and request optimization, the extension provides a fast and smooth translation experience.
