Check is our flagship software.

It’s an online workspace that lets users verify online photos and text, build datasets and structure open-source investigations.


This award-winning tool connects WhatsApp users to journalists, supports multi-newsroom fact-checking during breaking news, and crowdsourcing of investigative evidence. Check helps journalists, civil society organizations, researchers and human rights investigators on cutting-edge of information gathering and verification.

Open Source Investigations


Journalists, academics and fact-checkers use Check for collaborative reporting on elections. We help these users verify incoming content in real-time.

Open Source

Check allows members of the public to send content from social media and other online spaces to journalists working on investigative projects.


Check allows teams to translate content to and from multiple languages, accommodating both native scripts and common romanizations like Arabizi. The Check interface is localized in multiple languages, including Portuguese, Spanish and Arabic.


Partnering with some of the most prestigious academic institutions in the world, Check facilitates rigorous research into the nature and evolution of misinformation.

When we’re verifying user generated content, it’s very important to be clear and transparent. What’s great about Check is that it lets us show every step we’ve taken along the way. –Eliot Higgins on using Check for Bellingcat investigations

Check supports some of the largest collaborative reporting initiatives in history

During the 2016 presidential election day in the United States, Check supported Electionland, a national reporting effort covering voting problems during the 2016 election. A coalition of organizations – including ProPublica, Google News Lab, the USA TODAY NETWORK, Univision News, First Draft, WNYC, and the CUNY Graduate School of Journalism in New York – worked together to track the voter experience across the country in real time.
