Progressive display rendering of processed text

A method and a system are provided for processing displayed text and progressively displaying results of processing the displayed text. In some embodiments, displayed text may be submitted as processing requests to process portions of the displayed text. The processing may include translation of the portions of the displayed text from a source natural language to a target natural language, grammar checking of the portions of the displayed text, or other types of processing. Each of the processing requests may include one or more complete sentences, or other units of text. Further, each of the processing requests may be submitted independently of receiving a processing response corresponding to an immediately preceding submitted processing request. Changed or annotated text included in processing responses may replace corresponding displayed text.
