The headline feature was its "Advanced Document Recognition" engine. Unlike basic converters that treated every page as a giant image, 8.1 performed deep optical character recognition (OCR) that preserved not just text, but columns, tables, fonts, and even bullet-point hierarchies. It was a digital archaeologist, painstakingly reconstructing the original structure of a Word document from the flattened remains of a PDF. For legal assistants, researchers, and financial analysts, this was revolutionary. A scanned contract was no longer a picture; it was data.
