Optical Character Recognition (OCR) is the translation of images to machine readable text. Our product works best with PDF format documents, which is the de facto standard in electronic discovery exchange. There are currently limitations to OCR technology, such as recognizing handwriting or extremely poor quality scanned text. We use what we have found to be the most accurate OCR engine currently available. OCR technology continues to evolve and improve. If we find an OCR technology that is superior to our current solutions, we will adopt it. We continually evaluate OCR options.
