A few useful answers

Before you turn the page.

How is this different from Kindle + Google Translate?

Letrivio keeps the translation inside the page you are reading. Tap a word, sentence, or paragraph and continue from the same line — no selecting, copying, changing apps, or finding your place again.

Can I use my own books?

Yes. Photograph a printed page or import a PDF. Letrivio turns it into structured, interactive text while keeping page and paragraph references.

Does Letrivio work offline?

Yes. After the required language resources and your chosen on-device model are downloaded, OCR, translation, explanations, and study features work without a cloud inference fallback.

Which languages are supported?

Letrivio currently supports Spanish, English, German, French, Italian, Czech, and Slovak as reading and help languages.

When will Letrivio be available?

The first App Store release is in preparation for iPhone, iPad, and Mac. This page is ready for the final App Store link as soon as the listing is live.
