Grammatikwerkstatt

Tue, 08 Sep 2026 00:00:00 +0000

I designed and built Grammatikwerkstatt to turn German grammar study into active practice. It combines concise, source-checked explanations with varied exercises that ask learners to choose, build, correct, and write—not just read another table.

The experience covers 128 topics and 2,048 curated exercises from A1 to C1. Mixed sessions bring difficult forms back in new contexts, while progress stays on the learner’s device, so the entire product works without registration, advertising, or tracking.
