ABBYY Recognition Server is a powerful, server-based OCR application that processes documents behind the scenes while you work on more important things. It features a graphical workflow tool in the administration console. Features include the ability to watch a folder, OCR the contents, and move it to another folder. If a subfolder is dropped into the watched folder the system can create a corresponding subfolder in the output destination. It can also export documents directly to SharePoint. Another neat feature which was added in version 4 was the ability to determine non-searchable PDF documents in SharePoint, check them out, and then check in a new searchable version.
