Overview
Adds furigana only to kanji above your JLPT level.
Stop drilling flashcards and start reading real Japanese — news, X (Twitter), blogs, lyrics, manga sites — at exactly your level. Adaptive Furigana adds furigana (readings) to Japanese on any website, and the Pro version shows them ONLY on the kanji that are still above your JLPT level. The kanji you already know stay clean, so you read at the edge of your ability — true comprehensible input, right in your browser. ▍ Why learners love it • Read native content sooner — no more bouncing to a dictionary every other word • Learn by immersion — see readings only when you actually need them, and watch them disappear as you level up • Built for JLPT — set your level (N5–N1) and the extension adapts to you ▍ Free • Furigana on any Japanese site — readings above every kanji so you can read anything today • Click-to-define — click any word for its reading, part of speech, and meaning • Meanings in English or Korean (한국어 뜻 지원) — pick your language in the popup • 100% offline — tokenizer and dictionary are bundled in. No servers, no tracking, no account. Nothing you read ever leaves your device. • Per-site on/off, adjustable ruby size and color ▍ Pro (one-time purchase, no subscription) • Adaptive furigana — readings ONLY on kanji harder than your JLPT level (N5–N1) • Full dictionary — every sense of a word, tagged by part of speech • Example sentences — real Japanese with English translations • Read-aloud — hear native-like pronunciation (text-to-speech) Perfect for self-learners, JLPT candidates, anime & manga fans, and anyone doing immersion. The free version stays fully functional forever. ▍ Privacy No data collected, stored, or transmitted. Everything runs locally in your browser. Dictionary: JMdict/EDICT (EDRDG).
