1. A computer-based system for generating comparison output files indicating differences in annotations, comprising:

  • a memory storing instructions; and

    a processor configured to execute the instructions to;

    create a first index for a first electronic file;

    identify hidden characters for an insertion point and an end point of a first annotation in the first electronic file;

    identify a first portion of the first index between the identified hidden characters;

    create a second index for a second electronic file different than the first electronic file;

    compare the identified first portion with the second electronic file, to determine whether the second electronic file contains a matching annotation corresponding to the first annotation; and

    generate, based on the comparison, a comparison output file including information for displaying a modified appearance of characters in the first annotation to indicate that the second electronic file does not contain a matching annotation.
