# Image Data Extractor

Image Data Extractor is a Gradio app for extracting structured JSON from document images with [NuExtract3](https://huggingface.co/numind/NuExtract3).

Upload a receipt, invoice, or other document image, optionally add accompanying text, and choose a JSON template for schema-guided structured extraction. You can also generate a grounded template from the uploaded image before running extraction.

The inference function uses Hugging Face ZeroGPU dynamic GPU allocation. Select ZeroGPU in the Space hardware settings before launching the app.

## Run locally

Install the project dependencies and launch the Hugging Face Spaces entry point:

```bash
uv sync
uv run app.py
```

The Hugging Face Space starts from `app.py`. Model loading and the ZeroGPU pipelines are defined in `model.py`.
