Apply for access to the LIWC API


The LIWC API is available exclusively from Receptiviti. It provides approved developers and data scientists with an easy-to use API that delivers deep insights into people’s psychology and cognitive states by analyzing natural language and text.

The LIWC API generates all of the LIWC2015 variables, plus additional measures of psychology, personality, emotion, tone, sentiment and more.

If you're interested in using the LIWC API, please complete the short application form below - it's our way of getting to know you. We review all applications and typically respond to approved applications within 7-10 business days. Please note, we are very selective in our approval process, and only a small number of the applications we receive are approved.
