Parallèle Reader

Read the book you love, the original and its translation side by side. Save words and phrases, export your vocabulary. Reading that builds real fluency.

Read the books you love — and, whenever you like, read them in two languages, side by side.

Parallèle Reader is a calm, aesthetic everyday reader for your books. It also has a language companion built in: open a book in its original language and a clean translation appears right beside it — there when you need it, out of the way when you don't.

FEATURES

• Side-by-side bilingual reading in split screen — original and translation, page by page
• Translate on your device with Apple Translate, or connect your own DeepL key
• Hide the translation and reveal it with a tap to test yourself
• Long-press any word or passage to look it up, highlight it, add a note, or save it

WHO IT'S FOR

You just love reading — a distraction-free reader for your own library, with stats that make the habit stick. Language learners — read authentic books instead of exercises; reading in context teaches what flashcards can't. Heritage and bilingual readers — move freely between both your languages on every page. Anyone after a book that was never translated for sale — read the original with a translation alongside.

HOW IT WORKS

Open one of the included classics, or import your own EPUB, PDF, or text file.

In split screen, the original and a clean translation appear side by side, page by page — on your device with Apple Translate, or through your own DeepL key.

Long-press a word or passage to look it up, highlight it, add a note, or save it to your vocabulary. Prefer to test yourself? Hide the translation and reveal it with a tap.

PRICING

Try Parallèle Reader free for 7 days. After the trial, a single one-time purchase unlocks the full app.

PRIVACY

Your reading stays private. iCloud sync is optional and connects only your own devices through your Apple ID — your reading habits never reach our servers. Translate entirely on-device with Apple Translate, and if you add a DeepL key, it's stored securely on your device.

Whether you're rereading an old favorite or finally reading that novel in its original language, Parallèle Reader makes reading feel good — and quietly makes you better at it.
