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. de-de groups your mistakes by root cause and shows the recurring ones — that's what this 3-minute diagnosis demonstrates.
