Why a 3-minute diagnosis works

Most learners can name what's hard for them in the abstract, but can't see their own patterns.

  • The 4 prompts are designed to trigger the most common learner mistakes.
  • We surface only the most important recurring patterns — with quotes from your own text, not textbook examples.

If it lands, registering turns those patterns into your first lesson plan automatically.

Frequently Asked Questions

How long does the diagnosis take?
About 3 minutes. You answer 4 short German prompts and we analyze them in 10-15 seconds.
Do I need an account?
No. The diagnosis is completely free with no signup. Your answers are sent for analysis but not stored. If you register afterwards, the diagnosis becomes the seed for your first lessons.
Why is this better than just chatting with ChatGPT?
ChatGPT corrects each message in isolation but doesn't track patterns across sessions. mitDeutsch groups your mistakes by root cause and shows the recurring ones — that's what this 3-minute diagnosis demonstrates.
