What This Skill Does

The smart-ocr skill provides a robust interface for the PaddleOCR engine, allowing your OpenClaw agent to interpret and digitize visual information from various sources. It acts as an optical character recognition powerhouse, capable of processing images, screenshots, and scanned documents. By utilizing advanced machine learning models, the skill accurately identifies text characters, their spatial coordinates, and the confidence level of each detection, supporting over 100 languages. Whether you are dealing with clean digital text or complex handwritten notes, this skill translates visual data into machine-readable strings.

Installation

To integrate this skill into your environment, run the following command in your terminal:

clawhub install openclaw/skills/skills/duykhangdangzn1/smar

Ensure that you have the necessary system dependencies for image processing installed. The skill is designed to run efficiently on both CPU and GPU architectures, providing flexibility for resource-constrained or high-performance setups.

Use Cases

• Digitizing Paperwork: Automatically ingest physical invoices, receipts, or contracts into structured data formats.
• Data Extraction: Pull specific information from screenshots or interface captures for database entry or reporting.
• Language Translation: Detect and translate multilingual text within documents by pairing OCR results with translation modules.
• Accessibility: Transform text contained in static images into selectable, searchable, or accessible formats for assistive technology.
• Business Intelligence: Quickly process identification documents, business cards, or shipping labels during automated workflows.

Example Prompts

1. "Look at this screenshot of the invoice and extract the total amount and vendor name."
2. "Read the handwritten notes from this image and compile them into a plain text summary."
3. "OCR the attached document and translate the detected Chinese text into English."

Tips & Limitations

To achieve the best results, ensure images have high contrast and good lighting. While PaddleOCR is highly effective, extremely degraded or low-resolution images may yield lower confidence scores. If your text is in a specific language, explicitly declare the language code (e.g., 'ch' for Chinese, 'japan' for Japanese) in your configuration or prompt to increase recognition accuracy. For large-scale batch processing, enable GPU acceleration in the configuration settings to significantly reduce wait times. Note that handwriting recognition is supported but may require higher quality inputs than standard printed text to maintain precision.
