Chrome/Firefox/Opera extension which offers to inform its user about the “safety” of the websites they consult. The mechanism resembles a nudge, since it attempts to modify users’ choice architecture without ever restricting them. The tool does not solely concern news websites and can, for example, inform consumers on the quality of products sold on a website. It is therefore not strictly speaking an anti-fake news initiative. The tool is based on the opinions of users, rather than that of experts. It has been downloaded by more than 140 million Internet users.
