What Does The World Think?

🏆 Winner: Most Fun/Creative Project - Perplexity Hackathon

In our increasingly connected yet polarized world, the same claim can be interpreted vastly differently across countries and cultures. "What Does The World Think?" is an AI-powered global opinion analyzer that takes any statement and reveals how it would likely be received across 192 countries worldwide, helping people understand the subjectivity of "truth" and how cultural context shapes consensus.

Watch It In Action

The Challenge We Solved

The inspiration came from realizing how the same claim can be interpreted vastly differently across countries and cultures. We wanted to create a tool that could visualize these global differences in perspective, highlighting how cultural context shapes truth and consensus.

How It Works

The application analyzes claims against the cultural, political, and social contexts of different nations. Users can input any statement and receive a comprehensive Global Truth Index that indicates how universally agreed-upon the claim is. The system then visualizes agreement levels on an interactive world map, providing country-by-country breakdowns with detailed cultural context that explains why different regions might agree or disagree with the claim.

Technical Architecture

We built the application using React with TypeScript for a robust, type-safe frontend experience. The user interface leverages Tailwind CSS and shadcn-ui components to create a responsive, elegant design that works seamlessly across devices. For the interactive map visualization, we integrated Leaflet.js to display global perspectives geographically.

The AI backbone uses the Perplexity AI API for sophisticated global perspective analysis. We developed custom data processing workflows to transform AI-generated responses into meaningful visualizations, requiring extensive prompt optimization to ensure consistent, well-structured outputs across all 192 countries.

Technical Challenges Overcome

One of our biggest challenges was ensuring balanced representation of all global perspectives while accurately mapping country names to geographical data on the interactive map. We had to optimize our prompts to Perplexity AI extensively to produce consistent, well-structured responses that could handle the significant computational demands of analyzing 192 countries simultaneously.

Designing an intuitive user interface that could convey complex geopolitical nuance without overwhelming users required careful consideration of information architecture and visual hierarchy. We implemented robust data validation systems when working with AI-generated content to ensure reliability and accuracy.

Impact and Recognition

The project won the "Most Fun/Creative Project" award at the Perplexity Hackathon, recognizing both its technical innovation and practical value. When I shared the project on LinkedIn, it gained significant engagement from my professional network, demonstrating genuine interest in tools that help people understand global perspective differences.

The application successfully creates an accessible way for people to understand how subjective "truth" can be, making complex global data approachable for users regardless of their technical background. We developed a responsive map visualization that works across all devices and built a robust data processing pipeline that handles AI-generated responses reliably.

Future Vision

We're planning to implement historical tracking features that will show how global opinions evolve over time, adding detailed sources and citations for country-specific perspectives. Future updates will include comparison features for analyzing multiple claims side-by-side and creating shareable reports for educational and research purposes.

We're also exploring opportunities to expand the analysis to include regional variations within countries and developing a mobile application for on-the-go global perspective checks. The goal is to continue making global understanding more accessible and nuanced.
