Tesseract OCR is an open source, highly accurate image to text converter. Nevertheless, Tesseract OCR provides only command line interface.
JATI is just another interface to the Tesseract OCR engine, providing GUI interface to convert an image to text. It can do batch conversion, including converting only portion of the image into text.
