We are building the reliability infrastructure for the internet. Our tools give people the ability to identify signals they can use to determine the credibility of the information they consume.
WikiSignals is an open-source, reference reliability tool. The goal is helping people determine domain-level source credibility. Our focus is Wikipedians but its free for all (see Partners). We gather data from media indexes, ratings agencies, press membership directories, and web-related services. Use the search form above to check any of the (75,749) domains in our database.
