Press Information

rbutr is a community driven app which creates links between  webpages where the content of one page is a rebuttal against another. The content may be directly arguing against the original content, or generally presenting contradictory evidence. App users are alerted when they browse a rebutted page, providing them a link through to the rebuttal(s).

rbutr aims to facilitate inter-website debate, guide users to rebuttals of dubious information, and indirectly influence our users so that they approach all online information with an increased level of skepticism and critical appraisal.
