Practise the exam. Recognise your mistakes. Improve in a targeted way.
Ten things that set Sprachfuchs apart from a collection of tasks. The first two are the core: recognising mistakes and practising them in a targeted way.
- Exam practiceExams in the style of Goethe, telc and ÖSD, with a server clock like in the exam.
- Mistake analysis and exercisesYour mistake profile and training that consists only of your own mistakes.
- Feedback on speech and pronunciationSpeaking with an AI partner and a sound comparison that shows where the points go.
- Scored by the institutes’ criteriaWriting and speaking with points and reasons, like the original.
- Explained in your languageFeedback in German, English and Vietnamese.
Your mistakes, across all exercises
A single exam shows you what went wrong on one day. The mistake profile shows what keeps happening to you.
- Mistakes from all sources. From the evaluations of writing and speaking, from gap-fill texts and language-element tasks, from pronunciation exercises and from phrases. If you only get comprehension questions wrong, that does not count as a “mistake”.
- Four categories with a trend. Spelling, grammar, expression and pronunciation, plus the most common kinds, for example case, article or word order. The trend compares with the period before, from seven days up to a year.
- Recurring mistakes. The same place, made several times: this is where practice pays off most.
- Mistake cards. For each category the most frequent mistakes with the number of occurrences. The same place appears once, not ten times.
- Your words with spelling mistakes. A personal list instead of a general vocabulary notebook.

Learn from your mistakes
The core of Sprachfuchs: a test that consists only of your mistakes. Every new mistake makes it fit better.
- 20 tasks from your mistakes. You see the wrong place, in your own texts within the sentence where it stood, and type the correct version. A solved example comes first.
- Adapts to your level. What was wrong most recently comes most often, what you have never practised comes next. What you already had right comes less often. Frequent mistakes count more.
- Mistakes count as improved. As soon as you get a place right, the mistake counts as improved. The tile under “Practise” shows how many are still open and how many are already improved.
- Checked fairly. Quotation marks and final punctuation do not count, whole sentences are accepted too. If you disagree with the solution, you say so with one click.
- In your language. The hints appear in German, English or Vietnamese, the tasks stay German.

Exam mode without loopholes
Exam mode is a calm area of its own: no navigation, no distraction, one column like the exam booklet.
- Server clock. The time runs on the server: reloading or a second tab changes nothing. When time is up, your work is submitted automatically.
- Listening texts like in the exam. Start only once, no rewinding, number of plays according to the exam profile.
- No solutions in advance. Answers and explanations reach the browser only after you submit.
- Pause and carry on. The clock stops, your answers are saved automatically.
Scored in the manner of the institutes
Writing and speaking are scored by AI models following the respective institute, with its criteria, levels and pass rules.
- In the style of Goethe, telc and ÖSD, separately. Point tables and rules are stored as profiles, with sources. What is not secured is marked as open, not guessed.
- Several raters. Independent judgements are combined, and if they differ a third rating decides.
- Mistakes and improvements. A red cross for “instead of”, a green tick for “better”, the differing words underlined, grouped by category. Every mistake moves into the mistake profile and your training.
- Result sheet like on a certificate. Circle charts per part, criteria with comments, one click for detail.
Speaking with an AI conversation partner
More on this: Practise German speaking, B1, B2 and pronunciation practice.
The oral exam is what many people fear most. Sprachfuchs lets you practise it as often as you like, without an audience.
- Sequence like in the exam. The examiner’s instructions, preparation time with notes, then the conversation. The sequence for each part is stored in the profile of the exam style.
- Answers with a voice. You speak, your recording is transcribed, the partner answers in clear German that matches your level.
- Exact to the level. Length, choice of words and speaking speed of the partner follow A1 to C1, never a fixed B2.
Pronunciation that shows where the points go
Several measuring methods work together. The result is not a plain “good” or “bad” but a plan.
- Pauses, speed, intonation. Measured in the browser and compared with a template.
- A card for each sound. How often, in which words, and what the sound sounded like instead, for example ch, sch, ü, ö or r.
- Two suggestions per problem. An exercise and a piece of advice, right at the sound.
- Measured fairly. 100 % means the sound accuracy of a native speaker; measuring artefacts of the technology do not count against you.
The pronunciation evaluation is an orientation for practice, not an exam verdict.
ch (back)
6× off- Buch, noch, auch
- sounded like “sch”
ü
3× off- Müll, über
- sounded like “u”
Explained in your language
You practise German, but you really need to understand the feedback. All explanation texts are available in three languages, with one click on the flag.
- German, English, Vietnamese. Interface, hints and the reasons of the AI evaluation.
- The exam stays German. Only the explanation changes: tasks and your answers stay as they are.
„Wegen“ verlangt den Genitiv: wegen des Regens.
“Wegen” takes the genitive: wegen des Regens.
“Wegen” đi với cách 2 (Genitiv): wegen des Regens.
Concrete topics, checked exams
Good practice needs tasks that sound like a real exam, not like platitudes.
- New exams every week. At every level new practice exams are added weekly.
- Topic bank per level. 40 concrete starting scenes each, with area of life and tension; when an exam is generated no scene appears twice.
- Quality check. Every exam is checked against the profile, solved blind and criticised for arbitrariness.
- Level profiles. Text length, vocabulary, listening speed and strictness of scoring follow the CEFR can-do descriptors from A1 to C1.

Example: how an exam card shows a keyword for each skill.
Phrases, colloquial language and slang
Examples and exercises to look at: Phrases for the German exam, B1 and B2.
Good texts and conversations live from set phrases. There are exercises of their own for that, separated by level.
- Ten exercises. At each level from A1 to C1 one on phrases and one on colloquial language or slang.
- With explanation. Every task shows the solution and says why, including when a phrase is colloquial.
- Feeds into the mistake profile. Sprachfuchs remembers where you go wrong.
Stay on track together
Practising is easier with others. The community is voluntary and for adults only: you decide whether and how visible you are.
- Leaderboard. Learning points by week, month or 60 days, among everyone who can be found or only among friends. What counts is the amount of practice, not the grade.
- Private chat with friends. Text and voice messages, only between confirmed friends. Stored encrypted, without a passphrase and on any device.
- Report and block. You report inappropriate messages with one click, administrators can block accounts. Profile pictures are re-encoded, the original is never stored.
