Kotaemon provides two [PaddleOCR](https://github.com/PaddlePaddle/PaddleOCR) readers to enable document ingestion with full layout understanding, including multilingual text, tables, figures, formulas, and seals.
- `PaddleOCRVLReader`: Wraps the PaddleOCR-VL 1.5 visual-language model for robust layout and VQA-based parsing.
- `PPStructureV3Reader`: Uses the PPStructureV3 pipeline for structured layout analysis, including table and chart detection.
Both readers are located under `kotaemon/loaders/paddleocr_loader`.
## Prerequisites
- Install PaddlePaddle:
- Ensure that the installed PaddlePaddle version matches your system configuration and hardware (CPU/GPU). For additional wheel options, refer to the [PaddlePaddle official website](https://www.paddlepaddle.org.cn/install/quick?docurl=undefined).
- Check device support for [PaddleOCR-VL](https://www.paddleocr.ai/main/en/version3.x/pipeline_usage/PaddleOCR-VL.html#inference-device-support-for-paddleocr-vl).
```bash
# CPU
uv pip install paddlepaddle==3.3.0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
# gpu，requires GPU driver version ≥550.54.14 (Linux) or ≥550.54.14 (Windows)
uv pip install paddlepaddle-gpu==3.3.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu130/
```
- Install the PaddleOCR doc parser extras:
```bash
uv pip install -e "libs/kotaemon[paddleocr]"
```
- Configure the device: You can set the `PADDLE_DEVICE` environment variable in your .env file to control the execution device.
```bash
PADDLE_DEVICE=gpu # cpu, gpu:0
```
## Configure the loader
1. Run Kotaemon and open the app UI.
2. Navigate to Settings → File Loader (under indexing or ingestion settings).
3. Select one of the PaddleOCR loaders:
- `PaddleOCR PPStructureV3 (table+figure extraction)`
- `PaddleOCR-VL (VLM document parsing)`
4. Save the settings, then upload or ingest a document. Kotaemon will automatically use the selected PaddleOCR loader during indexing and convert extracted content into Document objects.
