"Decidim es una plataforma digital de democracia participativa desarrollada por el Ayuntamiento de Barcelona. Sus creadores la definen como un proyecto tecnopolítico que implica multitud de códigos más allá del informático. Emerge como ejemplo de lo que denominan “redes políticas" caracterizadas, frente a las “redes sociales”, por hacer del vínculo político y la construcción de inteligencia y voluntad colectivas el centro de su diseño y estructura. Este modelo de software libre tiene su réplica en Pamplona a través de Erabaki.” [Source](http://participa.pamplona.es/noticia/conferencia-decidim-redes-politicas-y-tecnopoliticas-para-la-democracia-participativa/) Decidim vs. CONSUL [feature table](https://docs.google.com/spreadsheets/d/e/2PACX-1vTKzaH-l8v-VeBdxVl2yfxmcJoruXkjCUIR9vkZVchlmC1ixW3HqSLzFQ264PRmagJU0GvpRd5WmMq9/pubhtml) and [blog post](https://xabier.barandiaran.net/2019/01/14/comparativa-decidim-vs-consul/) Watch: [Decidim and the Municipal Action Plan in Barcelona: co-producing and auditing public policy through a political network](https://www.youtube.com/watch?v=M0AbzoC1t78&t=2689s) featuring Pablo Aragón (Universitat Pompeu Fabra, Spain) Virgile Deville (Open Source Politics, Code for France, Democracy Earth) at mySociety's TICTeC

"Spam moderation, automatic translation, and accessibility. Spam moderation uses machine learning to flag suspicious content, reducing moderator workload while balancing accuracy and multilingual adaptation. The platform supports automatic translation, enabling inclusive discussions by integrating services like eTranslation. We have a pilot with the EU project IDEM to enhance accessibility for diverse users, with tools simplifying information for people with disabilities, seniors, and migrants in multiple languages."
