Viobean - German Exam Prep
Viobean
Prepare for the telc B1 & B2 Deutsch Zertifikat — not random practice.
Viobean is AI-powered exam prep built around the telc exam format. Every task, every scoring dimension, every exam section mirrors what you'll actually face on exam day. All four skills — plus Sprachbausteine — in authentic exam structure.
telc B1 & B2 EXAM FORMAT
Every Modelltest, every Übungstest, every Prüfungstraining session follows the real exam:
• Leseverstehen — exam-authentic reading passages
• Hörverstehen — listening at exam tempo
• Sprachbausteine — the grammar section telc actually tests
• Schriftlicher Ausdruck — written tasks with AI evaluation
• Mündliche Prüfung — all three Teile (Teil 1, 2, 3) with a conversational AI partner
AI EXPLAINS WHY — IN YOUR LANGUAGE
Every answer comes with a detailed grammar explanation, not just "right" or "wrong." Our AI teaches you the rule behind the answer so the next similar question gets easier. Available in 24 languages — read explanations in your native tongue while you practice in German.
AI WRITING EVALUATION
Submit your letters and essays and get structured feedback in seconds: grammar, vocabulary range, register, coherence, task fulfillment — the same dimensions a human rater scores. Rewrite, resubmit, watch your scores improve.
AI SPEAKING — REAL-TIME CONVERSATION
Have an actual German conversation with an AI partner that plays the examiner role:
• Teil 1 — introduce yourself and answer follow-ups
• Teil 2 — discuss a topic with a partner
• Teil 3 — plan something together
You get transcripts, turn-by-turn feedback on pronunciation, grammar, fluency, and task completion. No tutor scheduling, no exam-day nerves — practice until you're ready.
EXAMS SUPPORTED

TRACK YOUR PROGRESS
Practice history, past recordings, written submissions, and per-section scores all stay with you. See what's improved, identify weak spots, go into the exam knowing where you stand.
