Use your own library
Import EPUBs directly instead of waiting for a store catalog to support the book and language combination you need.
Inline vocabulary help beyond the Kindle ecosystem
Kindle Word Wise alternative for your own EPUBs
Word Wise made lightweight hints feel natural inside Kindle books. Jinshu brings that pattern to learner-owned EPUBs, with CEFR filtering and review built for language study.
Best for readers who like inline hints but want control over their own files and devices.
Filter by learner level
CEFR levels let you reduce noise instead of showing every possible hint.
Move from hint to memory
Saved words keep their sentence context and become review material.
How it compares
| Kindle Word Wise | Great inside supported Kindle books. |
|---|---|
| Generic EPUB readers | Flexible files, but little language scaffolding. |
| Jinshu | Inline vocabulary support for your own EPUB files, with CEFR and SRS. |
