Abstract
SMARTRIQS is an open-source add-on to the popular survey platform Qualtics, offering researchers the ability to design online surveys that feature real-time interaction between participants---including live text chat---without requiring researchers to learn any programming language or install any software. Using SMARTRIQS does not incur any additional costs to researchers who have an institutional Qualtrics account. This paper not only provides an overview of SMARTRIQS and its potential applications but also walks readers through the step-by-step instructions for setting up a particular study (Dictator Game with chat). These instructions start from the very basics, assuming no prior expertise in online experimentation, and are accessible to everyone, even those who are less---or not at all---familiar with Qualtrics.
