Inspiration

The digital age is flooded with misinformation. We realized that simple "True/False" fact-checkers aren't enough. They don't answer the why. The real danger isn't just a false claim, but the network of seemingly credible sources that spread it. Our inspiration was to build a tool that reveals this "why" by analyzing the source, not just the story.

What it does

Verifact is an AI-powered analysis tool that acts as your personal intelligence assistant. When you input a claim, it deploys a team of AI agents to investigate. It breaks down the submitted content into individual atomic claims and then searches web as well as the Google-FactCheck database to find relevant sources supporting or opposing the claim. It then generates a final verdict after verifying all the accumulated evidence to tell the user the veracity of the claims submitted.

How we built it

We built Verifact as a sequential, multi-agent pipeline using the Google ADK framework. The system is orchestrated by a main agent that coordinates specialized sub-agents. The pipeline has been deployed on Google Cloud Run. We've incorporated a lot of Google APIs such as Google Cloud Vision API, Google Search API, etc.

What we learned

We learned two key lessons:

An agent is only as good as its tools. The agent's entire perception of the web was filtered through the broken Google Search tool, and no amount of "prompting" could fix it. The solution was to change the tool.
The "data contract" is everything. In a multi-agent system, the exact JSON format passed between agents is critical. A single mismatched or dropped key (like claims being lost before the final agent) breaks the entire pipeline.

What's next for Verifact

Our foundation is solid, and we're excited to build on it. The next steps are to track how misinformation evolves. We plan to add an Event Evolution Tracker to map how narratives spread over time and an Image Provenance agent to detect when images are used in misleading contexts, making Verifact a more comprehensive, end-to-end analysis platform. We also plan on adding a much more powerful video analysis pipeline.
