I've used SimpleOCR, which has a nice GUI for correcting mistakes. Unfortunately it makes a lot of mistakes! (and suffers other bugs and limitations)
On the other hand Tesseract is more accurate but has no GUI at all.
My question is, is there a free OCR program for Windows which has a nice GUI and a low error rate? I want it to highlight suspect words (by OCR uncertainty, not just spell checking) and show the original (bitmap) word while I'm editing the OCRed word similar to what SimpleOCR does.
Open-source would be best, followed by freeware, then trial / demo / crippleware a long way behind.
