1. A method for optical character recognition (OCR) verification, the method comprising: receiving a first character image obtained during an OCR process applied to a text of a first document by an OCR-capable computer-based software application, wherein the first character image is classified by the OCR-capable computer-based software application as being associated with a first character; replacing a first display character of a text of a second document with the first character image, wherein the first display character corresponds to the first character that is associated with the first character image, wherein the second document is unrelated to the first document, and wherein the text of the second document is displayed on a display by a computer-based software application other than the OCR-capable computer-based software application; receiving a correctness evaluation of the association of the first character image with the first character, wherein the correctness evaluation is based upon a response of a user to the display of the first character image in place of the first display character of the text of the second document; and providing to the OCR-capable computer-based software application the correctness evaluation of the association of the first character image with the first character.
