Why a dictionary app breaks the story.

Every lookup in another app costs you the page you were on. Lexo keeps the word, the sentence and the translation on the same screen.

Copy, switch, paste, come back

  • You lose your place on every word
  • The translation ignores the sentence
  • Names and tone change from page to page
  • Nothing is saved to learn later

Lexo

  • Original and translation always side by side
  • Tap a word: meaning in its own sentence
  • The whole book translated with one style guide
  • Every word becomes a card, with the page it came from

Two languages, read your way.

Switch reading mode at any moment. Lexo keeps your place on the same sentence.

Side by side

Call me Ishmael. Some years ago, having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.

Whenever it is a damp, drizzly November in my soul, I account it high time to get to sea.

Llamadme Ismael. Hace unos años, con poco o ningún dinero en el bolsillo y nada que me interesara en tierra, pensé que navegaría un poco para ver la parte acuática del mundo.

Cada vez que en mi alma hay un noviembre húmedo y lluvioso, comprendo que es hora de hacerme a la mar.

Questions, answered.

Is Lexo free?

Lexo is free to download, and you can read the first pages of any book for free. Premium unlocks reading beyond the preview and removes the free limits on books and flashcards. Cloud features use Lexo AI coins; check the app for current plans and prices.

Do I need an account?

You do not need to create a Lexo account to start reading. Sign in to your Apple iCloud account if you want to sync between devices or use Lexo AI, which uses iCloud to keep track of your coins.

Which languages can I learn?

Choose the original and translation languages in the app. You can read in languages such as English, French, Spanish, German and Japanese. Available language pairs depend on the translation engine and your device; the language picker shows your options.

Can I use my own books?

Yes. Import your EPUBs and PDFs from Files or iCloud Drive, including comics in ZIP or CBZ archives. Translate a book into a second language, or merge two editions you already own into a parallel book.

How good are the translations?

Translations help you follow the story while keeping the original close by. Quality varies with the language, writing style and translation engine, especially for idioms or unusual dialogue. You can compare both versions and retranslate a paragraph when something looks wrong.

How do comics and manga get translated?

Lexo recognises the text on the page so you can look up words even when there is no selectable text. Lexo AI can translate comic and manga pages into a second edition to read alongside the original. Cloud translation needs an internet connection and uses coins.

What are Lexo AI coins?

Coins pay for cloud features such as Lexo AI translation and AI audio reading. The amount depends on the task and the options you choose. Check the cost in the app before starting, and add more coins when you need them.

Does it work offline?

You can read books and translations already saved on your device and review your saved flashcards offline. On-device translation requires the relevant language downloads first. Downloading books, iCloud sync and Lexo AI features need an internet connection.

Can I export my flashcards?

Yes. Export your flashcards as an Anki deck to keep reviewing in Anki. The export includes your cards and their review progress.

Which devices does it run on?

Lexo is available on iPhone, iPad and Mac, with Apple Watch for quick vocabulary reviews. Your library, reading position and flashcards can sync through iCloud across your reading devices.

Is my reading private?

Your library is stored on your device and can sync through your own iCloud account. On-device translation and text recognition run locally. When you choose a cloud feature such as Lexo AI, the content needed for that request is sent for processing.
