Readlate: EPUB Translator

Read foreign books with instant original/translation switching. EPUB, PDF, DOCX & TXT support, offline Apple translation packs, and Readlate Pro.

Readlate is a private document reader for people who read books, articles, notes, and handouts in another language. Open a file, translate the whole document with Apple Translation, then switch between the original and translated version whenever you need context.

READ FOREIGN DOCUMENTS MORE COMFORTABLY Readlate is built for foreign-language reading, not quick phrase lookup. Keep your place, return to recent documents, and continue reading after translation without rebuilding your library.

SUPPORTED FILE TYPES Open EPUB, PDF, DOCX, TXT, Markdown, HTML, and JSON files from the Files app, iCloud Drive, email attachments, or any document source available on iOS.

WHOLE-DOCUMENT TRANSLATION Translate full documents with Apple's Translation framework. Language packs can be downloaded from iOS, so supported language pairs can work offline after the required packs are installed.

ORIGINAL / TRANSLATED READING Switch between the original document and the translated version while keeping your reading position. This is useful when you want to check wording, compare meaning, or continue reading in the language that feels easiest.

RECENT DOCUMENTS THAT STAY ORGANIZED Return to your current books and documents from the recent library. Format badges, translated-language labels, and reading progress help you pick up where you left off.

READER TOOLS • Page and continuous scroll reading modes • Adjustable font size and font family • Table of contents navigation • Full-text search • Bookmarks • Custom tap-zone actions • Chapter and paragraph re-translation tools

EXPORT TRANSLATED FILES Save translated results back to the Files app. EPUB and DOCX exports keep their document-oriented workflow so translated material is easier to review or reuse.

PRIVACY-FIRST BY DESIGN Your documents are processed on your device. Readlate does not require an account and does not upload your documents to a Readlate server. Translation uses Apple's on-device/system translation capabilities depending on language availability and installed language packs.

SUPPORTED INTERFACE LANGUAGES Readlate is localized in English, Korean, Japanese, Simplified Chinese, Spanish, French, German, and Portuguese (Brazil).

READLATE PRO — ONE-TIME PURCHASE Readlate includes ads in the free experience. A single lifetime purchase unlocks Readlate Pro: no ads or reward gates, parallel original/translation reading, and bilingual export.
