Airesis is a free software platform, built by a team of Italian developers and contributors, to enable communities and groups to organize themselves in a productive manner according to the principles of direct democracy and participation. To achieve this goal, the application has been designed as a multifunctional system, which integrates all the tools that can help the development of a community, in particular "social" and deliberative tools. Of the social tools, Airesis offers blogs and a system of promotion of events and meetings with adjoining scheduling. Of the deliberative tools it includes areas for the collection and deliberation of proposals and initiatives, and a voting system aimed to the election of candidates. The platform also allows you to create groups with access to regulation policies and customizable permissions. Since the goal of Airesis is to stimulate participation, great attention has been spent in order to maximize the intuitiveness of the whole platform. The development philosophy is focused on continuous improvement, a kind of evolutionary process based on users feedback. The development team is available to meet the needs of the communities which want to use the software according to the spirit of direct democracy. Source code : https://github.com/coorasse/Airesis
