rbutr tells you when the webpage you are viewing has been disputed, rebutted or contradicted elsewhere on the internet. Last used 2013.

rbutr is a community-driven app which connects webpages together on the basis that one page argues against the other.

Visit a rebutted page and you will be told "There are rebuttals to this page." You can then open up the rebutting article(s).

Found a great rebuttal? Connect it to the page(s) it rebuts so that people reading those articles can know about it.

rbutr maps online rebuttals to bridge echo chambers, promote critical thinking and destroy misinformation wherever it is found.
