Requal is a free and open-source qualitative data analysis software that improves the reproducibility of qualitative coding by increasing its transparency and reflexivity. Requal is a shiny
application that runs in your browser and provides basic functionality
for annotating documents in plain text with user-defined codes. The
annotated text segments can be filtered and exported. Modules to enhance
reproducibility help users in making their analysis more transparent and reflexive.
To use the server version, you need to install Requal on a server or ask your organization's IT staff to install it for you. The server version is intended for online teamwork or teaching. You can try the demo version on our server:
requal.fsv.cuni.cz/demo/, user: demo, psw: requal123
