The Washington Post is spearheading lies in the political arena with the beta version of Truth Teller.
Truth Teller is a software that analyses political speeches, commentary and media pieces for lies. In a way, it is the future of fact checking.
As you watch a video on Truth Teller a rolling transcript plays next to the video highlighting sentences as they are said. When Truth Teller spots a false claim it highlights the quote and displays a link to the fact-check article.
They use the Fact Checker blog, Politifact and FactCheck.org. They are still working on the auto-transcription and some kinks, but the service is truly amazing. Now you can watch political speeches and know they are based in truth -- or lies.
