The document viewer is separated into three sections.
Along the top of the screen, the paper information bar shows the details about the primary document. This includes the document title, the author, the date the report was processed, the word count, the number of comparison documents provided and how many of those documents matched with the primary document.
The left panel is the paper text. This is the text of your primary document. Matching text is highlighted in a red.
Your comparison documents will appear in the sources panel to the right. This panel details the instances of matching text within the submitted documents.
By default, the doc-to-doc comparison will open the document viewer in the All Sources view. This view will list all the comparison documents you uploaded. Each comparison document has a percentage signifying the amount of content within them that is similar to the primary document. If a comparison document has no matching text with the primary document, it will be shown with a 0% next to it.
Doc-to-doc comparison can also be viewed in the Match Overview mode. In this view, the comparison documents will be listed with highest match percentage first and all the sources will be shown together, color-coded, on the paper text.
