Welcome to TwitterTrails, a tool that allows members of the media to track the trustworthiness of stories shared on Twitter.

We've examined 627 stories through TwitterTrails, so far. For each story, our algorithm measures how widely the story spread and how skeptical users are about its validity. By measuring crowd behavior, the TwitterTrails algorithm allows journalists to investigate claims and determine whether they appear to be true or false. Ask us to investigate a story for you.
