Lingoku is a browser extension that helps you learn Japanese naturally while watching anime, reading news, or browsing any website. It adds furigana readings above kanji, provides AI powered context specific meanings on hover, and distinguishes keigo politeness levels. You can save words with one click to create flashcards that include the original sentence, AI explanation, and JLPT level. The extension uses spaced repetition to resurface words before you forget them.
