Learning
Language learners reading real books
Read something you actually want to finish instead of a graded reader. When a sentence stops you, the translation is already there.
Bilingual reader
Bilingual books used to mean a printed edition someone else decided to make. Here every book you translate becomes one — the source text and the translation aligned paragraph by paragraph, in a reader that keeps your place.
Two layouts
They are not two skins on the same thing. Side by side is for checking a sentence against its source; stacked is for actually finishing the book. Switch mid-chapter.
Original
It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness.
It was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness.
It was the spring of hope, it was the winter of despair.
Translated
Đó là thời kỳ tốt đẹp nhất, cũng là thời kỳ tồi tệ nhất, là thời đại của sự khôn ngoan, cũng là thời đại của sự ngu xuẩn.
Đó là thời đại của niềm tin, cũng là thời đại của sự hoài nghi, là mùa của Ánh sáng, cũng là mùa của Bóng tối.
Đó là mùa xuân của hy vọng, cũng là mùa đông của tuyệt vọng.

Đó là thời đại của niềm tin, cũng là thời đại của sự hoài nghi, là mùa của Ánh sáng, cũng là mùa của Bóng tối.
It was the spring of hope, it was the winter of despair.
Đó là mùa xuân của hy vọng, cũng là mùa đông của tuyệt vọng.
Aligned paragraph by paragraph, so a glance across the gutter always lands on the same sentence.
Read your own book this wayInside the reader
The point of reading bilingually is that you never have to stop. A word, a phrase, a note — all of it happens in place.
Tap a word for a definition, IPA pronunciation with audio, and an example sentence. No second tab, no losing your line.
Select any run of text for an immediate translation, and change the tone if the default reading is not the one you want.
Mark a passage in one of four colours and attach a note. Both stay bound to the passage, not to a page number.
Position, highlights and notes live with the account. Stop on the laptop, carry on from the phone at the same paragraph.
Every word, one tap away
Lack of good sense or judgement — sự ngu xuẩn.
Select, translate, choose a tone
It was the season of Light, it was the season of Darkness.
Là mùa của Ánh sáng, cũng là mùa của Bóng tối.
Mark it, note it, find it later
It was the epoch of belief, it was the epoch of incredulity.
Note — the two clauses mirror each other; keep the parallel in the translation.
Stop here, resume there
Highlights, notes, bookmarks and position all travel with the account.
Who reads this way
A graded reader is easy to read and easy to abandon. A book you actually want to finish is harder — which is exactly why the translation should be sitting next to it.
Read something you actually want to finish instead of a graded reader. When a sentence stops you, the translation is already there.
Give students a side-by-side text so vocabulary and grammar are met in context, with pronunciation audio on the words that matter.
Read a paper or monograph with the original beside the translation and look up technical terms without leaving the passage.
Get through a long document in a language you read slowly, with the original always there to check a phrase against.
About bilingual reading
Layouts, alignment and what the reader can do
Something else?
Contact usA reader that shows the original text and its translation together, aligned so the two stay in step. In DualBook every book you translate becomes a bilingual edition automatically — you do not have to find one that someone published.
It depends on the sentence more than on the reader. Easy narrative goes faster stacked; dense argument, dialogue and unfamiliar terminology read better side by side. Switch whenever a chapter starts fighting you.
Paragraph by paragraph. A glance across the gutter always lands on the same sentence, which is what makes checking a phrase cheap enough that you actually do it.
Yes. Two columns become impractical on a narrow screen, so the stacked layout is the one to use there — a paragraph, then its translation directly underneath.
They live with your account rather than the browser, so you can switch machines and pick up at the same paragraph with your notes intact.
