Argunet Editor

Argunet Editor is a free argument map editor for analyzing and visualizing complex debates. You can use it offline and save your debates on your hard-disk. Or you can use it as a client-server application. This allows you to share your debates and collaborate with others on the Argunet server.

  • Fast sketching mode: You can use Argunet to quickly outline the macro-structure of a debate. Sketching debates is quite intuitive and you will get the hang of it without much effort.
  • Logical precision: In contrast to other argument mapping software, Argunet doesn’t stop there. It gives you the tools to go into every logical detail of an argument. This is where Argunet really shines: Every argument can be reconstructed as a logically valid premise-conclusion structure. Relations between arguments can be  systematically traced back to the logical relations between the sentences used as their premises and conclusions.
  • Support for different methods: Argunet doesn’t impose any special kind of logic or method on you. You can choose your own inference rules or argument schemes. And because it combines argument maps with the traditional “standard form” of single arguments as lists of premises and conclusions, Argunet is open to very different methods of argument reconstruction, ranging from simple mind-mapping to formal logic.

If this all sounds like gibberish to you, don’t worry. We have written some easy tutorials to get you going with your first argument map. This will only take a few minutes.


In order to run Argunet, a Java Runtime Environment 6.0 or higher has to be installed on your Computer. Please verify your current Java version here, and install an up-to-date version if necessary. If you have a 64bit version of your operations system you need to install the 64bit version of Java. If you have a 32bit operations system you need to install the 32bit version of Java. If you don’t know which version of Windows you have, read these instructions by Microsoft. If you don’t know which version of OSX you have, read these instructions by Apple.

Please select the download files for your operations system below and follow the install instructions.

After you installed your version of Argunet we highly recommend that you install the two plugins we currently provide: the yFiles Layouter and yFiles Exporter. Both plugins are provided seperately because they are based on proprietary code of yWorks and cannot be incorporated into open-source software.

To install the Argunet layout and export plugins open the ‘Help’ Menu in Argunet and select ‘Install Argunet plugins’. (Some users report problems installing the plugins. In case you’ve trouble installing them as well, you may consult our Argunet Mailing List, especially this thread.)
