CopyCatch Analyst is a set of programs which together offer detailed numerical, statistical, phrasal and vocabulary analysis of texts.

The programs have been used for authorship identification, witness and suspect statement analysis and stylometry.
History
Under the name of the Vocalyse Toolkit, CopyCatch Analyst has been in use within CFL's consultancy operation for the last 10 years, and has been assembled into a single package since 2003. The suite of programs allows the rapid analysis of suspect documents from 250 words upwards, producing statistical, vocabulary and phrasal information about the texts. It is specifically designed for use with the shorter texts associated with Forensic Linguistics but has also been used on much longer documents, particularly in the area of historical investigation of anonymous texts. The programs are not designed to undertake statistical authorship attribution in themselves, but they do supply the data which can be used in such systems.
