ExamDiff

ExamDiff is a slim, lightweight software tool to load and compare two different versions of the same document, or two related documents, to see where changes were made. It is a good tool for both students and teachers to review the changes that have been made to a document.

Pros

Quickly compares files for review: Whether you're checking for the first time or comparing files that have been updated a handful of times, ExamDiff will quickly check for differences and display them for you in a visual format that, while not cutting edge in terms of graphics, is very effective in laying out key differences.

Developer friendly output of your files: Saving differences in a standard UNIX DIFF file, the software is designed to display and save content in a format friendly to developers. Settings are highly customizable, and the interface is quick and responsive for moving between changes rapidly.

Cons

Lacks manual or tutorial: While the README file outlines each of the features and most of the options for using them, ExamDiff is limited when it comes to training or tutorials. For non tech-savvy users, the software will be tough to use to its fullest capacity.

Bottom Line

While not a perfect solution and only a nominal replacement for online tools that do the same, ExamDiff is effective for basic comparison functions of text content. Whether you are grading papers or writing your own and need to compare it to another version, ExamDiff will handle the basics effectively.
