Inspiration

“When we abandon facts, we abandon freedom.” — Timothy Snyder.

Misinformation is lethal:

• 232 000 Americans died in 15 months after vaccine-hoax posts deterred them from a free COVID shot.
  
• 330 000 South Africans lost their lives—and 35 000 babies were needlessly infected—because one speech denied the HIV-AIDS link.
  
• The viral Cluely “cheat-on-everything” AI now pumps out polished essays, deepfakes, even fake lab data, eroding trust in all AI. Every new pandemic and every election is a bigger target. That’s the blaze—Truely is our fire-extinguisher.

What It Does

Truely is a plug-and-play browser extension that unleashes a fleet of AI agents the instant a page loads:

How We Built It

Frontend:

• WXT (Web Extension Toolkit) for modern Chrome extension development with TypeScript
  
• Svelte 5 for reactive, component-based UI with excellent performance
  
• TailwindCSS for utility-first styling and responsive design

Backend:

• Chrome Extension Manifest V3 for secure background service workers and content scripts
  
• LETTA AI API for intelligent fact-checking and misinformation detection
  
• Anthropic Claude API as a secondary AI agent for robust analysis
  
• Custom DOM parsing engine to extract and clean webpage content for AI analysis
  
• WebExtension Messaging API for secure communication between extension components
  
• UUID-based action tracking for managing multiple fact-checking annotations

Architecture

Accomplishments We’re Proud Of

• Built a real-time AI fact-checker that flags misinformation directly in the browser
• Designed interactive annotations with clear, cited corrections that don’t interrupt reading
• Engineered a smart DOM pipeline that filters only essential user-visible content
• Shipped a performant and secure Manifest V3 Chrome Extension with advanced background capabilities

Learnings & Challenges

• Parsing complex, inconsistent DOM structures across the web
• Compressing large webpage text into limited AI context windows without losing key facts
• Building a seamless system to highlight and annotate dynamic content without breaking page layout
• Coordinating responses across multiple AI agents with different output formats

What’s Next

• Cross-page memory: Agents remember what you’ve seen and flag contradictions or recurring misinformation across sites.
• Custom AI agents, made by users: Anyone can deploy browser-native agents using just a prompt
• Monetization through agent marketplaces: Users can create, share, and even monetize their own agents via blockchain-powered rewards

Truth has a new home address: your browser. We’re not just fighting misinformation—we’re making honesty the default experience on the internet. Join us.
