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.

Core Features

⚡ Wortschatz-Trainer (SM-2 Spaced Repetition):
- Lückensatz im Kontext: Fill in the missing German word in realistic A2/B1 sentences.
- Aktiv Schreiben (EN → DE + Artikel): Active recall of both the German word and its grammatical gender (der, die, das).
- Artikel & Plural-Blitz: Rapid-fire noun gender and plural drill with morphological suffix rules.
- Karteikarte & Wortbau: Compound word and prefix breakdowns with de-DE native speech synthesis.
📖 Interaktive Leseecke (Graded Reader):
- Pre-loaded practical everyday German scenarios (Bürgeramt, Arztpraxis, Feierabend, Zugfahrt, Flohmarkt) plus custom text import.
- Click any word in any text for instant lemma, gender, plural, English translation, audio pronunciation, and 1-click saving into the SRS deck.
💬 Sprachpraxis (Vocabulary-Targeted Roleplay):
- Multi-turn real-world conversations that challenge you to weave 5 Zielwörter into your German responses, with real-time inflection detection and V2 / subordinate clause word-order coaching.
💾 Server + Local Persistence:
- Syncs vocabulary state across devices via /api/state (/app/data/wortkraft_state.json) with localStorage fallback.
