Juxta is an "open-source tool for comparing and collating multiple witnesses to a single textual work". Juxta was originally designed to facilitate the scholarly study of the history of a text from manuscript to print versions. Juxta has evolved into a multi-platform desktop application that "allows users to complete many of the necessary operations of textual criticism on digital texts (TXT and XML). With this software, you can add or remove witnesses to a comparison set, switch the base text at will. Once you’ve collated a comparison, Juxta also offers several kinds of analytic visualizations". The standalone Juxta applications facilitates annotation and save the results of collation as an working platform for analysis.
