PaperPort is commercial document management software published by Nuance Communications, used for working with scanned documents, Depending on the version, PaperPort can use its built-in optical character recognition to create files in searchable Portable Document Format (PDF); text in these files is indexed and can be searched for with appropriate software, such as Microsoft's Windows Search. Earlier versions of PaperPort used Nuance's OmniPage to provide this function.
