How it works

From any file to a parallel text

Three steps, and the first look is free: every file starts with a preview of its opening before you spend a single page.

  1. 1

    Bring a book or document

    EPUB and text-based PDF work best. Plain text and HTML files work too, or paste text straight in.

Who it's for

For anyone who reads in two languages

A translation replaces the original. A parallel edition keeps both, so you choose how much of each you need.

  • Reading in your second language

    Living abroad, studying in another language, or just more comfortable in your own? The lease, the letter from the tax office, the novel on your nightstand: read the original with a safety net beside it.

  • Learning a language

    Read stories you'd pick anyway, in the language you're learning. When a line stops you, the meaning is a glance away.

  • Bilingual families

    Share one text across two languages, so parents and kids, or grandparents and grandkids, can read the same story, or the same school letter, together.

  • Anyone who needs the original

    Keep the exact wording in front of you, whether it's an author's prose, a paper you'll cite or a clause you'll sign, while a translation carries you through.

Why side by side

The meaning is already on the page

Read in the language you choose and look across only when you need to. A parallel edition keeps you inside the story instead of bouncing between the book and a dictionary.

Als Gregor Samsa eines Morgens aus unruhigen Träumen erwachte, fand er sich in seinem Bett zu einem ungeheueren Ungeziefer verwandelt. Er lag auf seinem panzerartig harten Rücken…

Dictionary

Ungeziefer n.

1. vermin, pests 2. (fig.) …

The dictionary wayStop. Look it up. Lose the thread.

Als Gregor Samsa eines Morgens aus unruhigen Träumen erwachte …

When Gregor Samsa woke one morning from troubled dreams …

… fand er sich in seinem Bett zu einem ungeheueren Ungeziefer verwandelt.

… he found himself transformed in his bed into a monstrous vermin.

Er lag auf seinem panzerartig harten Rücken …

He lay on his armour-hard back …

The DuoText wayGlance across. Keep reading.
Paragraph by paragraph
Every paragraph sits next to its translation, so when a line stops you, the answer is a glance away, not an app away.
The original, kept
A translation alone puts someone else's words between you and the author. Here the author's words stay on the page.
Yours to keep
Download the parallel book and read it offline on your own device, in your own time.

Translation quality

Careful with the words, honest about the limits

Translations that follow the story, not just the words.

Translated in context
Each paragraph is translated as a whole, not word by word, so pronouns, tenses and tone carry from one sentence to the next.
Made for stories
Tuned for fiction: dialogue, narration and long sentences, not menus and manuals.
Nothing goes missing
Every paragraph stays paired with its translation, so you never lose your place.
Honest about the limits
Puns, poetry and dialect can come out flatter than the original. It's a reading companion, not a certified translation.
