About

Trilinguo

Features
Read full description

Trilinguo turns any book into a gentle language lesson. Every passage is shown in the original language with translations stacked right beneath it β€” a sentence or two at a time β€” so you learn while you read something you actually want to finish. No flashcards. No drills. No streaks to lose. Just a book, in three languages at once. HOW IT WORKS β€’ Bring a book β€” import your own PDF or EPUB, or open one of a hundred public-domain classics built in. β€’ Read it stacked β€” the original on top, your practice language beneath, and an optional third language below that. One passage per page, nothing else on screen. β€’ Keep the words β€” tap any word for an instant lookup and save it to your vocabulary; highlight and annotate as you go. A HUNDRED CLASSICS, READY TO READ Austen, BrontΓ«, Dickens, Conrad, Twain and more β€” every passage already translated, so the first page opens instantly. Practice languages include Spanish, French, German, Italian, Portuguese, Dutch, Russian, Macedonian, Japanese and Chinese. PRIVATE BY DESIGN No account required. No ads, no analytics, no tracking. Your library, notes and vocabulary stay on your device. Books are sourced from the public domain.
