Anyone know of a free screen capture ocr program that works from batch commands. I have been using ScreenOCR SDK and its perfect. But its $149 and its time limit is up, Any GPL or freeware programs like this out there?

It captures a specific part of the screen, converts it to txt and saves it in a file for me, then I have autohotkey read the txt file and act on the results.
