HO:PE is a European Commission-funded project that focuses on creating and implementing tools for tackling antisemitism online, hate crimes, and harmful content. Its components, which include a browser extension and a mobile application, aim to make reporting antisemitic content quick and effective, allowing users to report incidents with just a few clicks. HO:PE is designed to support Jewish communities in all 27 EU member states to tackle the growing threat of antisemitism online. This tool will facilitate the documentation and reporting of antisemitic incidents, thereby empowering Jewish communities and civil society organizations to respond more effectively to online hate.
