About this app

Learn a language by reading the books you love. Biblyx turns any EPUB, PDF, or TXT into personalized vocabulary lessons — tap any word, get an instant translation, and remember it for good.

Unlike traditional language learning apps, Biblyx uses real books as your lessons. Your books are the lesson. Read real novels, classics, articles, and stories in the language you’re learning, and build your vocabulary from the words that truly matter to you.

No childish games. No generic courses. Just you, your books, and real reading.
