Check, developed by Meedan, is a platform for collaborative verification of digital media. The Check project builds online tools to improve the investigative quality of citizen journalism and help limit the rapid spread of rumors and misinformation online. Using Check you can quickly build a team, add social media links to fact-check them, set key questions for investigating news items gathered amongst your team.

Check’s browser extension allows you to quickly add media items that you come across on the internet to your Check team for investigation, and answer tasks concerning these items right from within the extension’s sidebar. Here’s how you can use it:

Browse the internet, and find a Tweet, YouTube video, Facebook post or an Instagram photo that you want your team to fact-check and investigate. Click the Check icon, choose one of the projects you want to add this item to, and save it.

The extension also detects if the item already exists in Check, and shows you the relevant tasks to be answered concerning it in the sidebar. Select a task, then highlight text from the page: the text will automatically populate the task answer.

You can also highlight text from an article, a web page, or an incoming WhatsApp Web message. Right click, select the Check icon, and choose one of the projects you want to add this text to.

The extension works on Tweetdeck for web and other tools that operate on the browser.

On Check, you can see this item added as media on your team and you can start the verification process right away. Here’s what you can do on Check for fact-checking:

Add journalists and citizen journalists to your team so that they can contribute to the verification process.

Ask questions about media items, like date, time, location and evidence to help deciding if it’s true or fake.

Add a verification status to each media item you have on your team to reflect the result of the fact-checking process like, verified, false or in progress.

If you work in digital media and want to try out Check as a way to streamline and coordinate your social news gathering and verification workflow, please visit https://meedan.com/en/check.

Is Check Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Check requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Check has earned a fairly good reputation and likely can be trusted.
