CaptainFact is a collaborative fact-checking tool for YouTube videos.

People help each others to verify informations in this way: 1. Video is added on the website. 2. Statements are extracted from the video. 3. Fact-checkers confirm or refute the statements. All CaptainFact's extension users will see our verifications directly on YouTube video. The fact-checking is done collaboratively. Everyone can share their knowledge to fight against: inaccuracies and omissions; distortions of information (voluntary or not); information put out of context; fake news ; pseudo-sciences, rhetological fallacies, intellectual dishonesty, demagogy, untruths, or other.
