Description
Stop looking up words. Start reading.
Every English learner knows the pain: you open an English book, hit an unknown word on the first page, switch to your dictionary app, look it up, switch back, lose your place, and repeat. By page three, you've given up.
Jinshu eliminates this cycle entirely. Import any English book and every vocabulary word is automatically annotated with translations in Chinese, Korean, or Japanese — right where you need them, right as you read.
SMART VOCABULARY ANNOTATIONS
- Words annotated automatically from a ~30,000-word dictionary with CEFR levels (A1-C2)
- Choose your display: ruby text above words, inline parentheses, or tap-to-reveal
- Set your proficiency level — only see annotations for words you're still learning
- IPA pronunciation for every annotated word
- Translations in 中文, 한국어, and 日本語
TAP ANY WORD TO LEARN IT
- First tap: hear the word pronounced aloud
- Second tap: see IPA, translation, CEFR level, and full details
- One tap to save any word to your vocabulary book with its sentence context
- Saved words become spaced-repetition flashcards — review at scientifically optimal intervals
- FSRS algorithm (used by Anki) schedules reviews so words stick in long-term memory
LISTEN TO BOOKS READ ALOUD
