What is Jinshu?
Jinshu is a level-aware EPUB reader for English learners. You bring your own real books; Jinshu checks the fit, surfaces repeated above-level words, and adds CEFR annotations, translations, pronunciation, TTS, and review without turning reading into a separate lesson.
Built for learners who would rather read than drill.
Generic readers show the book. Course apps show lessons. Jinshu sits between them: original books stay readable, while level-aware guidance shows which hard words deserve attention before and during reading.
