Build your vocabulary in historical languages by reading iconic texts in Latin, Greek, French, Arabic, and German. Instead of practicing language with boring stock sentences, read the real texts that shaped civilization. For centuries, scholars learned languages by studying significant texts, not canned exercises. In CodexTutor, we are inspired by that approach. HOW IT WORKS A passage arrives as a stack of cards, one chunk of the original on each. Read it. Tap to check the translation. Swipe right if you had it, left if you didn't. Tap any word for its dictionary entry: headword, part of speech, what it means. No hovering crib telling you what the sentence says. The lexicon is at your elbow and the meaning is yours to assemble. At the end, you will be able to read the whole passage. Then, you will move on to the next passage! VOCABULARY THAT KNOWS YOUR TEXT Every text carries its own vocabulary, ordered by how often each word appears in that text — not a generic frequency list. When previewing vocabulary, high frequency words are prioritized. The system is meant to making reading the real text easier. THE LIBRARY Readers can choose from iconic texts in Latin, Greek, Arabic, French, and German. Modern languages and some ancient texts have audio. Homer and Virgil. More texts are always being added. WORKS OFFLINE. NO ACCOUNT. Texts download once and stay on your phone. There is no sign-in, nothing to subscribe to, and nothing about your reading leaves your device.
