The FiB Chrome extension analyzes your Facebook feed for a url, picture, and text's validity. It was built by four students as part of Princeton University's hackathon, with the challenge to solve Facebook's problem with fake news.

HOW IT WORKS

• The extension goes through your Facebook feed in real time as you browse, and verifies the authenticity of posts. These posts can be status updates, images or links.
• The back-end AI checks the facts within these posts and verifies them using image recognition, keyword extraction, and source verification, and a twitter search to verify if a screenshot of a Twitter update posted is authentic.
• The posts then are visually tagged on the top right corner in accordance with their trust score. If a post is found to be false, the AI tries to find the truth and shows it to you.
