About this app

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 will actually face on exam day. All four skills -- plus Sprachbausteine -- in authentic exam structure.

telc B1 & B2 EXAM FORMAT
Every Modelltest, every Uebungstest, every Pruefungstraining session follows the real exam:
- Leseverstehen -- exam-authentic reading passages
- Hoerverstehen -- listening at exam tempo
- Sprachbausteine -- the grammar section telc actually tests
- Schriftlicher Ausdruck -- written tasks with AI evaluation
- Muendliche Pruefung -- 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 18 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 are ready.
