Description: Linguistic Inquiry and Word Count (LIWC) is a text analysis technology that calculates the degree to which people use different categories of words across a wide array of texts, including emails, speeches, poems, or transcribed daily speech. This technology can analyze hundreds of standard American Standard Code for Information Interchange (ASCII) text files or Microsoft (MS) Word documents and allows the building of custom dictionaries to analyze dimensions of language relevant to specific interests.

This product can be licensed for either Academic/ University use or Commercial use. License fees for the Academic product license can either be paid as a monthly `rental` or purchased one-time as an unlimited duration license. The Commercial license includes a 30-day trial period and access to the LIWC Application Programming Interface (API) which generates LIWC2015 variables and includes additional features and models for analysis that are not available with the Academic licensed product. Users get the same base product with either license.
