description: "Browser tool that adds furigana (kana pronunciation guides) above kanji in any Japanese text — context-aware via Sudachi and ModernBERT, so 上 reads correctly as 'うえ' or 'じょう' for the sentence."

Furigana — the small kana written above kanji to indicate pronunciation — is what Japanese readers stop needing as they advance but every learner relies on. Existing tools annotate naively; EzFurigana uses Sudachi tokenization plus a ModernBERT context model so the right reading is picked. Paste any text in, get a properly annotated version out. Free.
