Corpus Term Frequencies shows overall word frequencies for the entire corpus as well as information about how word frequencies are spread out over documents within the corpus. Hover over column headers and buttons for more information.

Document Term Frequencies shows word frequencies for each document in the corpus. You can see the selected word at the top of the window highlighted in yellow. Its relevance to the documents is shown in the table below.

Wmatrix is a free tool for corpus analysis and comparison. It provides a web interface for USAS and CLAWS, in addition to enabling standard corpus linguistic functions such as frequency lists and concordances.

HyperPo is an important legacy tool, developed as the first web-based text analysis tool aimed at humanities scholars available from 1996 through 2006. Users could input a web address, upload a file or directly enter text for analysis. HyperPo's interface was available in both English and French. Though no longer available for use, a capture of HyperPo can be viewed through the Internet Archive's Wayback Machine.

ABFREQ was a tool for identifying key words within a text developed in the 1980s. It identified key words by comparing thier frequency within the user's text to the frequency of the same words in a control corpus.

This software scans one or many Word DOCX, text and text-like files (e.g. HTML and XML files) and counts the number of occurrences of the different words or phrases. There is no limit on the size of an input text file. The words/phrases which are found can be displayed alphabetically or by frequency. The program can be told to allow or disallow words with numerals, hyphens, apostrophes, underscores or colons, to ignore words which are short or which occur infrequently, and to ignore words (e.g., common words such as 'the', a.k.a. stop words) contained in a specified file. It can also count only words or phrases in a specified list (optionally with pattern-matching). Results can be exported to Excel for further processing. The program works with text in most European languages, and supports the use of regular expressions for specifying words/phrases to count.

This software scans a Word DOCX file or a text file (including HTML and XML files) with text encoded via ANSI or UTF-8 and counts the frequencies of different words. The words which are found and displayed can be ordered alphabetically or by frequency. Characters which can appear in words can be specified, so the program can be told to allow or disallow words with numerals, hyphens, apostrophes, underscores or colons, to ignore words which are short or which occur infrequently, to treat upper/lower case as significant or not, and to ignore words (e.g., common words such as 'this', a.k.a. stop words) contained in a specified file. This software may be used with text in most European languages. The language of the text is detected automatically and (if supported) the corresponding stop words file is optionally loaded. Results can be exported to Excel for further processing. There is also an Advanced Version with greater functionality.

AntWordProfiler is free software for analyzing word frequency.
