Main features
Compare document versions in different file formats. For example, you can compare a text document and an image (a scan, a photo, a PDF document without a text layer, etc.). The compared texts must be written in English or in Russian.
Examine the differences in a handy side-by-side view. Clicking a difference in the results pane will immediately highlight the corresponding fragment in both versions.
Focus on what's really important - insertions, deletions, and other substantial changes to the original text. Minor differences in formatting, fonts, spaces, and tabs will be ignored.
Save comparison results as a difference report or as an annotated PDF document, with each difference highlighted and supplied with a comment.
Start using the program right away, as its uncluttered and intuitive interface is straightforward and self-explanatory.
