Riyarchy is an online collaborative argument tree platform where users can submit arguments to the issues they care about. These arguments will then be public for everyone to review and refute if deemed necessary.
Riyarchy's mission is to conclude debates that should have ended long ago, and it does this by being able to summarize the argument tree using rules of simple logic. By showing that most or all undefeated arguments on a particular issue support a certain side, Riyarchy effectively proves that one side is correct, and the other side is false.
