I've been scouring the web for things like this for a while; open source tools that can represent an argument process in a visual manner reminiscent of a workflow. There is obviously kialo.com, but it doesn't quite tick all the boxes IMO. Interest in this kind of thing additionally seems to have died out a few years back. Are we waiting for an AI solution perhaps? In the meantime Argdown perhaps is the closest thing available.
