Today I had an image of a document that I needed to convert to text. In this age of free web apps I wondered whether there was a Free OCR web app. I found Jon Galloway’s post which basically concludes there are no satisfactory free OCR app. He did find Microsoft Office Document Imaging acceptable, but its not free and its not on the web. It comes with Microsoft Office XP and Microsoft Office 2003. I also discovered this web OCR app, but I did not get a chance to try it because the document I needed to OCR was in PDF format.
All this got me wondering whether Google will provide a free OCR app in the future. Google is doing a load of OCR work with their Book Search project. Did Google write its own OCR software or did it purchase the software from a third party? Duff Johnson proposes Google wrote its own OCR software. If Google did, it might be easy for them to provide that app free to everyone. Will they?
