LingoReader: Book Translator

LingoReader is a free ebook reader and book translator in one app. Read your own books offline, with no ads and no account, and translate a whole book with AI when you need it. Reading is free; translation is paid separately.

Books with translation in minutes
Add a book in Spanish, German, French or another language, and AI translates the whole book: chapters, dialogue and structure stay in place. The finished translation stays on your phone and works offline, and the original is always one tap away.

A reader with translation for language learners
Read books in a foreign language with the translation at hand: check the translation where the original is hard, then go back to the language you are learning. Learning a language with books is easier when bilingual reading takes one tap.

AI book translator:
• more than 40 languages, 13 of them quality-checked;
• the whole book is translated, not single phrases;
• names and terms stay consistent across the book;
• several translations of one book, picked right in the reader;
• export to EPUB.

A comfortable EPUB, FB2 and PDF reader:
• opens EPUB, FB2, PDF, TXT, MOBI and AZW3 without DRM;
• font, size, spacing, margins and page color;
• page turning or scrolling, volume key page turns;
• reading aloud with your phone's voice;
• audiobooks in MP3, M4A and M4B with chapters, speed and a sleep timer;
• light and dark themes;
• the app speaks 12 languages;
• bookmarks, table of contents and search in the book;
• quotes with color highlights and notes.

Reading statistics: time, speed, day streak and rereading history.

Sync: keep your books, translations, progress, bookmarks and quotes on your own Google Drive and open them on another phone.

Privacy: your books stay on your device and, if you turn on sync, on your own Google Drive. Book text goes to the server only when you start a translation yourself, and it is deleted within a day after the translation ends. You can delete your account in the app.

This app is for your own files: there is no built-in book store.

Reading, statistics and export are free. Book translation is paid with characters: you top up your balance after signing in with Google, and purchased characters don't expire.
