Download for MacPrivate library
Read and translate books from your own collection without using the app as a book source.
Local AI
Read your books in any language when privacy matters.
Books-translater is for readers who want EPUB and PDF translation without sending their library through a web-based copy-paste workflow. Local AI keeps translation on your machine when enabled.
Local workflow
A private reading workspace for long-form translation.
Local AI is most useful when the document is long, personal, paid, or sensitive enough that uploading it to a browser translator is not the right workflow.
Offline sessions
Keep studying even when a web translator is unavailable or distracting.
Readable output
Use translation as a companion to reading, notes, highlights, and export.
FAQ
