Shiritai — Furigana Reader for Japanese

Add furigana readings to Japanese text on any web page and explain selected text with study cards.

Read real Japanese, everywhere. Shiritai adds furigana readings to Japanese text on any web page — news, social media, blogs, Wikipedia — and turns every word into a look-up. ★ Furigana on everything Instant readings above kanji on any page. Adjust the reading size to what's comfortable. ★ One-click dictionary Click any word to see its reading, dictionary form, and JMdict definitions — in English, German, Russian, Spanish, or Chinese. Tap 🔊 to hear the pronunciation. ★ See the melody Every lookup draws the word's pitch-accent contour — the rise and fall that makes 箸 (chopsticks) sound different from 橋 (bridge). ★ Know what you know Color words by JLPT difficulty (N5–N1) and hide readings for levels you've already mastered, so furigana appears only where you need it. ★ Reading comfort A reading ruler that dims everything except the line you're on, and optional word spacing (分かち書き) that adds small gaps between words. ★ Go deeper Select any text, right-click → "Explain with Shiritai" for a full breakdown on shiritai.app: translations, grammar, vocabulary, kanji, and a study summary. Everything runs locally in your browser — the tokenizer and dictionary are bundled with the extension. No text is sent anywhere unless you ask for a full explanation. Dictionary: JMdict (EDRDG). Pitch accents: kanjium (CC BY-SA 4.0). Chinese glosses: Tomoshi open data (CC BY-SA 4.0). Kanji levels: kanji-data (MIT).
