About Us

Factchequeado is an initiative created to counter mis and disinformation within the Hispanic and Latino communities in the United States. An innovative project led by, the first Spanish non-profit fact-checking media created to combat disinformation in Spain, and Chequeado, the first fact-checking media organization in Argentina and the Global South.  

Both organizations are characterized by innovation in approaching their audiences, creating proactive communities, fostering collaborative work, expanding journalist’s networks and developing civic technology.

They united forces in 2021 to draw on their proven experience to fill a gap and find a solution for Spanish-speaking communities especially vulnerable to mis-disinformation. This is a community of 60 million Hispanics and Latinos living in the U.S., which by 2030 will represent more than 20% of the country's population. 

As a result, it has become fundamental to produce fact-checked content in Spanish especially aimed at these underserved communities to limit the impact of mis and disinformation by collaborating alongside fact-checking organizations and local media outlets to facilitating their access to verified information through Spanish speaking media in the U.S. and the different platforms they use for news consumption and sharing.

What we do

Factchequeado is:

  • A digital medium of mis-disinformation verification that creates open-source original Spanish content, available on various platforms and social networks.
  • A collaborative alliance with large and small Latino media and fact-checking organizations aimed at increasing the focus on these underserved communities. 
  • A One-on-One community, providing crowdsourcing tools to educate and learn about the informational needs of the different Hispanic and Latino communities in the US, while respecting their language and culture. 
  • A space for training on fact-checking tools and fighting disinformation for U.S. journalists, with a clear focus on Hispanic journalists.
  • An innovation lab to fight disinformation that will develop new formats through experimentation and exploration of new technologies.
  • A database for academics interested in investigating disinformation in Spanish in the United States.

Factchequeado fact-checks the mis and disinformation circulating on social networks and mass media through quality journalism.

We listen to our audience's needs and focus on platforms such as Facebook, TikTok, YouTube, Twitter, WhatsApp, Telegram, and other news outlets, to help citizens know whether the content they receive is accurate, false, based on little or no evidence, or lacks context.

We use investigative and data journalism tools, images, and video verification techniques, which any citizen can learn, to help our community make decisions based on facts, not gossip, rumors, prejudice, or speculation.

Learn with us: training opportunities

We believe that journalism is a service of public interest, and as such, it must be of quality, transparent, innovative, and collaborative.

We believe collaboration with citizens, with local media that help us hear first-hand the relevant issues of the communities, and with the large press -national and international- that follow the public agenda is essential for our denials and fact-checks to go further.

We can all learn to verify information! At Factchequeado, we offer educational tools so that citizens can check the content they receive and avoid sharing unverified content and thus increasing the problem of disinformation.

Become our partner 

At Factchequeado, we believe that journalism is a service of public interest, and as such, it must be transparent, innovative, and of high standards of quality, but above all collaborative.

One of our premises is impact: we want more and more people to have access to verified information and the tools to identify and check if what they consume is true or false, lacks evidence, or needs a better context.

To achieve this, we partner with other media in Spanish and English in the United States, large and small, allowing them to publish our verified quality content for free, in innovative formats, and have access to our educational and pedagogical tools.

In that collaborative synergy, our allies help us understand their communities, their priorities and their needs, which allows our team of talented journalists in the United States to identify the stories and the issues to monitor.

Quality journalism, like what we create at Factchequeado, is expensive. We need funds to produce information based on the best available evidence and present it in a timely manner and in formats that resonate with the community.

Creating a network of media organizations, training journalists, empowering citizens, and building a community of Hispanics and Latinos to counter mis- and disinformation in the U.S. is possible with funding from donors, in addition to Chequeado and financing their respective contributions to Factchequeado. 

We are committed to operating with a diversified funding model, which guarantees our sustainability and autonomy. We are also committed to being transparent about who finances and supports us.

We want to thank the Google News Initiative, which offered us our first grant to launch Factchequeado. Additional thanks go to the American Board of Internal Medicine (ABIM) Foundation, which awarded Factchequeado with a $80,000 prize to combat medical and health misinformation claims, with a focus on those that are trending on WhatsApp. With support from the Knight Foundation ($150,000), we are also working on the project: “Spanish-Language WhatsApp Misinfo Intervention - Staffing: Support fact-checker staffing at Factchequeado to combat Spanish-language misinformation on WhatsApp around the 2022 U.S. midterm elections.”
