# WortKraft — Active German A2/B1 Vocabulary & Context Studio

**WortKraft** is a self-hosted German learning application built to bridge the "1,400-day Duolingo plateau" by transitioning from passive multiple-choice recognition to **active recall, grammatical gender mastery (`der`/`die`/`das`), contextual reading, and targeted sentence production**.
