Tap a word. Hear it in both.
This is the reader, running in your browser. Tap a word on either side and see its twin.
Made on your computer
Translate a book in the desktop app and give the translation its own voice. Save both in one synced EPUB.
Your place, in both
Save words, find them again, and search both languages at once.
On older iPhones, too
On iOS 15 and 16, two-language books open in a simpler two-pane reader.
Want to try one? The public shelf in Reader has two-language editions to download: Frankenstein in English and Bulgarian, Alice in English and French, A Christmas Carol in English and Spanish, and Dr Jekyll and Mr Hyde in English and Italian. Each is narrated in both languages.
English read by Kokoro, a free voice in Libratory. German by Cartesia, a cloud voice you can add with your own key.
One sentence at a time
Sentence pairs reads each sentence, then its translation. Give each language its own speed, hear it up to five times, and leave a pause to say it back.
Set it up the way you would in the app, then press play.
German twice at its usual pace, then a pause to say it back. Then English once at its usual pace. About 19 seconds a sentence.
Es war in einer trüben Novembernacht, als ich die Vollendung meiner Mühen erblickte.
It was on a dreary night of November that I beheld the accomplishment of my toils.

Tap the tip to hear the word on its own, as many times as you like.
Keep it

- 3. Give each language a voiceThen send the book to your phone. Scan the code on the app's Phone page, or use AirDrop or Files.
Next: say it back, and hear how it went
The pause after a sentence already gives you time to say it aloud. Speaking practice will listen and tell you how close you came.
It is not built yet. If you want it, open the listening options in a two-language book and tap Speaking practice (Beta). Tell us which language you are practising.
Questions
Is it free?
Yes. Reader is free on the App Store, and the desktop app is free for personal use. Online models and voices are optional, and their providers charge for them.
Which languages can I learn?
Any pair the translation model knows. Free voices on your computer read English, German, Spanish, French, Italian, Portuguese, Hindi, Mandarin and Bulgarian, among others. Other languages can use an online voice.
Is the translation made by AI?
Yes. A language model you choose translates each chapter. It reads well, but it can be wrong, so the original is always beside it.
Do I need the internet?
Only to get a book. Reading and listening work offline, with no account.
Is there an Android app?
Not yet. Reader is for iPhone and iPad. The desktop app runs on Mac, Linux and Windows.
