The main objective of the eComparatio project was to develop a software that is able to achieve an extremely accurate alignment of a text-diff-analysis in a synoptic representation. You can use eComparatio as a tool to compare text or as a tool to prepare your digital text edition. It provides superior visualization and it outperforms competitors like Tustep, collateX or alternatives because it is the most powerfull text diff software that also incorporates a solution for text transposition. The tool is realized as an browser based local application.
