Bring your own books into duoBooks. Import EPUB and FB2 files straight from your device. You read them just like the books in our catalog. Translate any sentence with one tap. Look up words and save them to your personal dictionary. Importing is free, and your books stay yours.
duoBooks does more than swap one word for another. When you tap a word, it also looks at the whole sentence. So the translation matches how the word is really used. This works for idioms and phrasal verbs too. Tap a sentence and you get a natural translation that keeps the author's tone. An ordinary translator misses this context when you paste in a line.
While you read, save any word to your personal dictionary. Each word is saved with the sentence you found it in. You also get phonetics, synonyms, and definitions. Saved words turn into spaced-repetition flashcards. The review schedule helps you remember them. You can also hear any word or sentence read aloud. Translation works from any book language into any reading language.
