Kotonoki

From anime into kanji, kana, and meaning. Each episode becomes a focused Japanese lesson — with native audio, furigana, and JLPT-aware vocabulary.

Kotonoki turns the anime you already love into a focused Japanese learning routine. Pick a series, tap an episode, and Kotonoki builds a custom lesson around the words actually said in that scene — with kanji on top, furigana underneath, and Hepburn romaji as a safety net.

Built for learners from JLPT N5 (high beginner) through to N1. Pick your level during onboarding and Kotonoki surfaces vocabulary at and slightly above it. Use as many crutches as you need today; drop them as you grow.

Three layers of meaning on every word

• Kanji as the standard Japanese writing
• Kana reading shown above (furigana style) so you're never blocked
• Hepburn romaji underneath, plus a tap-to-hear native voice for pronunciation

How it works

1. Search any anime — Frieren, Spy×Family, Demon Slayer — or browse what other learners have already added.
2. Tap an episode. Kotonoki pulls real Japanese subtitles and extracts the words that matter for your level.
3. Practice with flashcards (kanji + reading + audio), translation choices, and cloze fill-ins.
4. Words you've learned come back at the right moment — Leitner-style spaced repetition tuned to JLPT levels.
