How to Translate an EPUB Book While Reading

Step-by-step workflow

1. Import the EPUBOpen the book in Reader Alive using Files, AirDrop, iCloud Drive, Wi-Fi transfer or the Share Sheet.
2. Read firstStart with the original text so you keep the author's structure and phrasing in view.
3. Translate selected textUse selected-text translation for sentences, paragraphs or terms that block comprehension.
4. Translate larger sections carefullyUse chapter translation to preview structure, but return to the original when meaning matters.
5. Save your reading flowAfter checking a translation, continue from the same place instead of jumping between apps.

Why not translate everything

For language learning, translating every sentence can reduce practice. A better pattern is to read until you hit friction, translate the passage that blocks you and then continue in the original.

For research, translation can help identify whether a chapter is relevant before you spend time on close reading.

What Reader Alive sends to AI providers

When you explicitly use translation, selected text or relevant excerpts may be sent to an AI service provider to complete the request. Ordinary reading is separate from that action.

This control matters because many readers want AI help only at specific moments, not constant processing of every page.

How Reader Alive supports the workflow

The workflow in this guide is designed for personal files, not for a single-store library. Reader Alive supports EPUB, PDF, MOBI and AZW3, so the same import habits can work across several kinds of books. Files, AirDrop, Finder, iCloud Drive, Wi-Fi transfer and the iOS Share Sheet all matter because readers usually collect books from more than one place.

A good test is to run the workflow with one easy file and one difficult file. The easy file confirms that the transfer path works. The difficult file reveals problems like DRM protection, broken metadata, scanned PDF pages or a format mismatch. Solving those issues early prevents a large library import from becoming messy.

Limits and honest expectations

There are also limits worth stating clearly. Reader Alive is intended for books and documents you can legally import and open. DRM-protected files may not work in third-party readers. Scanned or image-only PDFs can limit text-to-speech, summaries and book-aware questions because those features depend on usable text.

AI features are explicit actions. When you use translation, text-to-speech, summaries, voice input or book-aware chat, selected text, relevant excerpts, audio input or your question may be sent to AI service providers to complete that request. Ordinary reading and file storage are separate from choosing to use an AI feature.

For important study, legal, medical, financial or academic work, verify AI summaries and answers against the original text. The strongest use of Reader Alive is as a close-reading companion: it helps you stay oriented, but the book remains the source of truth.
