WatchOCR is free OCR server for PDFs. Based on Knoppix, WatchOCR uses cuneiform, and exactimage to create text searchable PDFs from image only PDFs. Using the web interface, WatchOCR can be remotely configured to monitor a watched folder for newly scanned PDFs for OCR conversion. Leveraging the power of a liveCD distro, WatchOCR is the fastest way to get an OCR service up and running for your network.
