Now I know all you geeky writers out there keep your work backed up properly.
But you still may find this website useful. It can take scanned images of typed pages and convert them back to word documents so you edit the text. It can't do handwriting - but it can do typed text. So perhaps your only copy of a script is a printed out hardcopy - now you can retro it back to a computer file. Or if it is from the typewriter era you can now get it in an editable form for the first time ever. It is free - up to 30 pages per day.
Perhaps a more commonly used feature for us would be the 'pdf to word' feature. Take that locked down pdf and turn it into an editable word doc.
