Argüman is a collaborative argument mapping and analysis platform. It allows users to visually map out arguments, objections, premises and fallacies. The open-source project was developed between 2014-2015 primarily by members of the Python Istanbul community. It currently supports English, Turkish and Chinese and uses technologies like Python, Django, and databases to allow over 4,000 users to create and analyze nearly 15,000 premises and 1,900 arguments.
