Which OCR engine is used by default when using the "Get OCR Text Activity"?

The "Get OCR Text Activity" in the context of Robotic Process Automation (RPA) typically uses the Microsoft OCR engine by default. Microsoft OCR is integrated within many automation platforms, providing efficient text recognition capabilities for images and scanned documents.

Using tools like Microsoft OCR allows for optimized performance in environments where Microsoft technologies are prevalent. It's designed to work well with documents generated in Microsoft applications, but also supports a broad range of image formats and layouts.

In contrast, while Tesseract and ABBYY FineReader are powerful OCR engines, they are not the default choice within the "Get OCR Text Activity." Tesseract, for example, is an open-source optical character recognition engine known for its flexibility, but it may require additional configuration for optimal use. Similarly, ABBYY FineReader is a commercial solution renowned for its accuracy and extensive features, yet it is not the standard engine in most RPA setups unless specifically integrated or configured to be. Google OCR, while capable, is less commonly used in certain RPA tools compared to Microsoft OCR due to the default settings.

Thus, the correct choice highlights the standard technology that delivers reliable results in the context of RPA activities that require text extraction.
