## Was ist German-OCR-3?
**German-OCR-3** ist eine kompakte, schnelle und voll lokal lauffähige **Vision-OCR-Distribution für deutsche Geschäftsdokumente** — Rechnungen, Briefe, Formulare, Quittungen, Bescheide. Aus dem Bild kommt **strikt validiertes JSON** nach unserem deutschen Extraktions-Schema. Ohne Cloud-Pflicht, ohne Vendor-Lock-in.
Zwei Editionen, beide Apache 2.0, beide unter 3 GB:
| Edition | Ollama | Größe | Zielhardware | Stärke |
|---|---|---:|---|---|
| **Nano** | `Keyvan/german-ocr-nano` | **1.0 GB** | CPU · Edge · Mobile | „läuft überall" |
| **Default** ⭐ | `Keyvan/german-ocr-3` | **2.7 GB** | 4–6 GB VRAM | beste Field-Erkennung |
> **Fine-tuned adapter** für deutsche Geschäftsdokument-Extraktion. Apache 2.0.

## 🎯 Zielgruppen
- **Solo-Builder & Indies** — deutsche Dokumente lokal extrahieren, ohne Cloud-OCR-Kosten.
- **DACH-KMU mit Datenschutz-Anspruch** — lokal / on-prem hosten.
- **Agenturen & Studios** — Open-Source-Fundament unter der eigenen Pipeline.
Wer es **gemanagt** und mit noch größeren Modellen will:
> 🌐 **[german-ocr.de](https://german-ocr.de)** — gehostete deutsche OCR-API mit Premium-Modellen, höherer Genauigkeit, ohne eigene Hardware. Daten bleiben in der EU.
---
## ⚠️ Limitations
- Optimiert für **deutsche** Dokumente — andere Sprachen keine Garantie.
- Beste Qualität bei klaren, hochauflösenden Scans/Fotos.
- Handschriftliche Dokumente: nur begrenzt.
- Bei kritischen Vorgängen (Buchhaltung, Recht): **immer Human-in-the-Loop**.
