Last updated on 12 May 2026

How can you help your students take a step back and think before sharing information on social networks? Media of instantaneous and sharing, social networks are real click-traps where images and videos circulate and diffuse at the speed of light. How can we avoid falling into the traps set consciously or unconsciously on its new information highways?

Here are three extensions for your browser that will help you find the fake of the real. They will never replace a real thorough check and time for reflection, but they can help avoid the biggest socks.

InVid Verification

This plugin presents itself as a verification ‘Swiss knife’ allowing journalists or citizens to save time and be more efficient in their tasks of checking videos and images circulating on social networks. The extension for Chrome is still a beta version, but updates are regular. The tools provided allow you to quickly get contextual information about Facebook and YouTube videos, perform reverse image search on search engines, capture key images of videos and then be able to improve and explore them through a magnifying glass. A real online detective kit.

Decodex

This plugin offered by the decoder service of the newspaper Le Monde makes it possible at a glance to assess the quality of the site you are consulting. This extension, once installed on your browser, tells you in real time whether the sites and profiles on social networks (Twitter, Facebook, YouTube) that you visit are rather reliable or not.
The Decodex is also more than 900 false information items listed on the decoder website, with detailed decryption accessible in one click. The extension icon, a capital D, will change colour depending on the reliability of the site you are visiting. The yellow colour indicates that there are doubts about the reliability of the information provided on the website. The red clearly indicates that the site is not reliable at all Finally, the creators of Decodex had the good idea to reserve a color, blue, to identify satyric sites that by nature can distort information, but without pursuing a malicious objective

Trusted News

It is somewhat the same principle that governs Trusted News. The extension relies on databases from recognised fact-checking organisations. When you visit a news site, the extension icon in the top right corner of the browser will show you the level of trust attributed. Green colour and words ‘ trustworthy » if the content is found to be reliable, Red colour and ‘u’ntrustworthy if the content is not considered trustworthy, Colour grey finally if the site is not part of the database of evaluated sites. Trusted News only measures sites in English, but it can be a good complement to Decodex.
