• Goethe-/ÖSD-Zertifikat B1 — all four modules: Lesen, Hören, Schreiben, Sprechen, with Lesen and Hören module mock exams
• telc B1 and telc B2 — every section, including Sprachbausteine, plus full mock exams
• telc A2
• A1 (Start Deutsch 1) — also offered by the Goethe-Institut as Goethe-Zertifikat A1
• More exams coming soon

SPEAK WITH AN AI PARTNER — IN REAL TIME
The oral exam can be hard to practise alone. In Viobean you talk with an AI Partner, live, the way the Sprechen part really works: introduce yourself, discuss a topic, plan something together. Afterwards you get a transcript and turn-by-turn feedback on grammar, vocabulary, fluency and task completion. Practise until you're ready.

AI FEEDBACK ON YOUR WRITING
Write your letter, e-mail or forum post and get structured feedback in seconds on the criteria examiners use: task completion, coherence, vocabulary, grammar and register. Rewrite, resubmit, and track your practice results.

GRAMMAR LESSONS IN THE LEARN TAB
Short, clear A1 grammar lessons with examples, then practice rounds that bring back what you got wrong until it sticks.

EVERY ANSWER EXPLAINED — IN YOUR LANGUAGE
Viobean doesn't just say "right" or "wrong". Each answer comes with the grammar rule behind it, in any of 30 languages, while you practise in German.

MOCK EXAMS AND RESULTS BY SECTION
Sit a timed mock exam, see your result for each section, and know exactly which Teil to work on next. A daily plan tells you what to practise today.

NOTEBOOK AND FLASHCARDS
Tap any word in a reading or listening task for an instant explanation, save it to your Notebook, and review it as flashcards on a spaced-repetition schedule.
