Better OCR API

So I really liked the OCR screenshot plugin that was made a while back. However, I remember that it used tesseract OCR. In my opinion, is a far better engine. Is there a way to use this instead? I don't have enough coding knowledge to build this, but I believe that people other than myself would find it very useful to make a screen capture macro out of this API. There is copyfish, but that only works in chrome.
