Hermesian wins Rep. Jim Himes’ 2025 Congressional App Challenge in Connecticut’s Fourth District
Rep. Jim Himes has named Sierra Mendoza of Greenwich High School as the winner of the 2025 Congressional App Challenge in Connecticut’s Fourth District. Their app Hermesian is a web application for media literacy that uses artificial intelligence to assist users in critically analyzing news.
When asked what inspired the creation of Hermesian, Sierra Mendoza said, “The Washington Post headline, ‘FIRST US CASE OF POTENTIALLY DEADLY CHINESE CORONAVIRUS CONFIRMED IN WASHINGTON STATE,’ sparked my interest in civic awareness and the Hermesian vision precisely four years ago. That one instance helped me to fully comprehend the immediate and significant impact that news has on influencing public opinion, public policy, and our day-to-day existence. I came to see that awareness is the first and most important step toward an informed and functional society; it is not merely an abstract idea.
“But as I committed to remaining informed, I soon encountered the obstacles that many people, particularly my peers, must overcome. Information overload was the first issue; the news seemed to be a never-ending deluge of in-depth articles. Disengagement was the second issue. Consuming news the old-fashioned way can be tedious. Growing skepticism was the third and most important issue. Finding news is no longer as important as trusting it. Cynicism results from the difficulty of determining what is credible in the face of so much contradicting information and covert bias.
“I was motivated to create Hermesian for this reason. I think the experience itself is the issue, not just the content. We must alter the way we engage with information. My answer is Hermesian. It is intended to be a clear, simple, and approachable tool that takes on overload and skepticism head-on. It offers a robust, on-demand AI-powered analysis to help users see through the clutter, rather than just displaying more news. Hermesian fosters trust and enables users to interact with the world critically and curiously by exposing bias, rhetoric, and factuality.”
The 2025 Congressional App Challenge marked another record-setting year for the program. A total of 394 Members of the U.S. House of Representatives hosted App Challenges in their congressional districts, the highest level of participation in the program’s history. More than 13,800 students from across the country participated, submitting over 4,600 original apps focused on real-world challenges ranging from health and accessibility to education, sustainability, and civic engagement.
The Congressional App Challenge is an official initiative of the U.S. House of Representatives that encourages middle school and high school students to learn to code, explore computer science, and build practical technology solutions for their communities. Each participating Member of Congress selects a winning app from their district, and winning teams are invited to showcase their projects to Members of Congress, staff, and industry leaders at the annual #HouseOfCode celebration on Capitol Hill.
The Challenge is proudly bipartisan and reflects a shared commitment to expanding access to STEM education and preparing the next generation of American innovators for the future workforce. The program is a public-private partnership made possible through funding from the Broadcom Foundation, AWS, Infosys Foundation USA, theCoderSchool, Apple, and others.
The 2026 Congressional App Challenge will launch in May, and eligible students can pre-register for the competition now.
