- A page-difficulty estimate that becomes personalized to your actual vocabulary once you've marked ~10+ words known

Privacy: Tokenization runs entirely in-browser (via kuromoji.js) — no page text is ever sent anywhere. All data stays in local browser storage.

Word definitions use JMdict (EDRDG), used under their licence. Kanji difficulty data from kanji-data (MIT).
