- List of optical character recognition software
-
An OCR SDK is a software development kit for adding optical character recognition capabilities to forms processing applications, document imaging management systems, e-discovery systems and records management solutions.
In order to avoid the difficulties of incorporating OCR technology, some OCR SDKs contain a high number of APIs, support multiple operating systems and programming languages.
Here is a non-exhaustive comparison of optical character recognition software:
