I'd like to scan a good amount of papers I have lying around, with the least possible hassle. I would like to convert them to images using Simple Scan, then convert them to text using OCR. Is there a good OCR app with a GUI that will give me good results at the push of a button?
Have a look at this page.
Tesseract can only read a TIFF file - if you've got a JPEG or PDF or whatever, you'll have to convert it. Also, the filename extension must be .tif, not .tiff, otherwise tesseract errors out.
disclaimer - I am closely connected with the development of this opensource solution
Lios can convert print to text using either scanner or a camera.
It can also produce text out of scanned images from other sources such as Pdf, Image or Folder containing Images.
Program is given total accessibility for visually impaired.
Since I'm closely connected - I would love feedback.
There are few popular OCR command-line tools you can use (I'm not sure if they've GUI):
