Bring your own EPUBs
Jinshu does not lock learning inside a curated catalog. You can import novels, essays, course readings, Markdown, PDFs, and web articles, then keep reading on mobile or e-ink.
Read real books, learn real English
EPUB reader for English learners
Jinshu is built for learners who already have books they want to read. Import an EPUB, keep the original text, and let vocabulary help appear exactly where the hard words show up.
Best for independent readers who want native books, not another closed lesson library.
See vocabulary without leaving the page
CEFR-level annotations, translations, and pronunciation stay inline so the reading flow does not turn into constant dictionary switching.
Turn reading into review
Words you look up or save keep the original sentence and move into spaced repetition, so review starts from the book context.
How it compares
| Generic EPUB readers | Good for layout, weak for language learning. |
|---|---|
| Graded-reader apps | Good for lessons, weak for your own books. |
| Jinshu | Combines personal EPUB reading with CEFR vocabulary support and review. |
Common questions
Can I import my own EPUB files?
Yes. Jinshu is designed around bring-your-own-book reading. EPUB is the best-supported format.
Is Jinshu only for English?
English learning is the core search position, and the app also supports Chinese, Japanese, and Korean annotation systems.
Does Jinshu work offline?
Reading, local dictionary lookup, and imported books work offline. Optional cloud voice and sync features need a network.
