The optical character recognition software is an automatically run process that helps in converting images like PDFs into a searchable & editable file format. Its biggest example is the conversion of a PDF file into a doc file. With Klippa, Nanonets, Docparser, IBM Datacap, AWS Textract, and more tolls, you can do it easily.
But, nothing can beat the efficiency and excellence of bespoke OCR solutions. There are companies, such as Eminenture that does scripting in their own way using Python, and other programming languages and databases for customizing the file conversion via the OCR process. It can also be the best example of bespoke OCR solutions.
