All 43 chapters are open, in six tracks and both languages: from your first line of code, through machine learning and deep learning, to language models, agents and the open questions of the field. Every lesson starts with a picture you move, and the code runs inside the lesson.

The journey, flashcards, the level test, chapter exams, XP, levels and badges all work with no account. Premium adds the tutor, voice calls and sync across your devices.

The journey, lessons in three depths, quizzes that start from pictures, flashcards with spaced review and the level test. Your progress, streak and XP stay on this device.

The landing page, the full curriculum map and pricing are live in both languages. The learner app, the placement test and the first chapters are next.
