I have that application on my computer.
It came bundled with a Lexmark 3-in-one.
I also wasn't to sure about the size of it versus the benefit.
Basically, it is an OCR ... Optical Character Reader.
I tested it using grocery store receipts.
Scanned 'em and the file, which is not an image file like a Photoshop .png or .jpg, was editable.
I think I had it open in .rtf (Wordpad ... rich text format) 'cause I used boldface & colored type.
I found, after several hours of playing with it, that I had a functional set of techniques worked out
that made it possible to have a easy to read, categorical shopping list complete with current prices.
I was then becoming more selective about how I fed the cashier the groceries in the cart,
to save copy/pasting those receipts.
I tested it on newspaper articles.
I felt like an editor again, chopping up the news and copy/pasting it I saw fit.
It takes some getting used to, some errors are made by it that simply demand correction manually.
Strange new words appear in the middle of sentences,
not bad ... probably 5% ... but there none the less.
The latest copyright date on version 5 is 2001.
It was old software when I got it.
Naturally the folks at ABBYY want to sell me an upgrade, I recall some info provided,
but no nag screens popup at least.
Generally speaking, if you have a scanner, having an OCR program is better than having none.
