Read the texts that changed the world
Learn Latin, Ancient Greek, Arabic, French, and German by studying the foundational texts of our civilization.

How it works
Read the original, one passage at a time
Famous texts have been broken down into accessible passages you can learn to read in one sitting.
Guided Reading
Swipe through a passage chunk by chunk. Tap a chunk for its translation, tap a word for its gloss — you assemble the sense yourself.
Passage by Passage
Long works are laid out in passages you can finish. Each one you read is marked, and the book fills in behind you.
Why CodexTutor
Built for serious learners
Every text is analyzed in advance — each word glossed, each line’s grammar prepared.
Tap Any Word
Tap a word for its dictionary form, part of speech, and meaning — then assemble the sense yourself, the way you read with a lexicon. The grammar’s there when you want it, tucked away when you don’t.

Real Texts, Not Textbooks
You're not learning from fabricated examples. Every line and every phrase comes directly from literature that people actually read.
Watch the Book Fill In
Every passage you finish is marked. Watch a whole text fill in behind you, passage by passage, until you have read the thing entire.
Every Language, Done Right
