Dualex teaches you both sides of a language: the formal academic register (CEFR A1.1–C2.2) AND the everyday street language people actually speak.

📘 Academic Track (Blue Path)
Structured CEFR lessons from complete beginner (A1.1) to advanced (C2.2), covering grammar and vocabulary for real progression. The German Academic track is independently audited — A1–B1 levels align to Goethe-Institut standards.

🗣️ Street Language Track (Orange Path)
Learn the language people actually speak — real everyday expressions and casual conversation you won't find in a textbook. The German Street Language track is audited and verified with zero critical or major findings.

🧠 Smart Review (SM-2 spaced repetition)
Our review system tracks what you know and when you're likely to forget it — so you revise at the optimal moment. Every flashcard adapts to your performance.

🔊 Natural AI Voices (Wavenet TTS)
Listen to any word or sentence in natural voices, with adjustable speed.
