When Local AI is enabled, book files stay on your Mac instead of being uploaded.
Mac App Store
Read your EPUB books in any language, privately on your Mac.
Books-translater helps Mac users read foreign-language EPUB and PDF books with local AI translation, original text, translated text, highlights, notes, and export in one reading workspace.
Why offline matters
Your book library should not become upload material.
Offline translation is useful for private notes, paid ebooks, research PDFs, and long books where copying text into a web chat breaks concentration.
Long-form reading
Move through chapters while preserving a stable reading and study workspace.
Export for review
Save a translated EPUB for personal study after the translation is complete.
