Pass the DTZ — on the first attempt
The DTZ (German integration exam) gates residency and citizenship. People preparing juggle books, YouTube and scattered PDFs — with no real exam simulation, no feedback and no explanation in their own language.
We built AstroLingua as a complete DTZ trainer: every exam part across listening, reading, writing and speaking, an AI conversation partner with Azure neural voices (DE/AT/CH accents), essay grading by photo or text, and a Leitner spaced-repetition system for vocabulary — UI in 12 languages, explanations in the learner’s mother tongue.
A learning platform that realistically simulates the DTZ instead of just collecting material: 2,900+ words, grammar A1–B2, AI coaching and real exam tasks — free during beta.
- All four skills: listening, reading, writing, speaking
- AI conversation partner with 6 Azure neural voices
- Essay grading by photo or text, Leitner vocabulary
