Inspiration
- The rapid spread of misinformation in the digital age, amplified by social media and unverified news sources, inspired us to build this tool
- Traditional fact-checking methods are slow, often manual, and lack real-time adaptability to dynamic information flows.
- Perplexity’s Sonar Pro API, with its real-time web search and advanced reasoning, provided a unique opportunity to build a
What it does
- Our platform that analyzes news articles, breaks them into individual claims, and verifies them using Perplexity’s Sonar Pro API.
- It fetches real-time articles via NewsAPI, personalizes content based on user interests, and stores data in MongoDB.
- Then, the platform ranks sources using authenticity and tonality metrics, provides highlighted source excerpts, and generates shareable reports
How we built it
- The platform integrates Firebase Authentication for secure email/password signup, email verification, and profile management, storing user data (country, interests) in MongoDB for personalization.
- We use NewsAPI api-key to fetch, store and use(ONLY THE METADATA NOT ARTICLE CONTENT) in UI which are then evaluated by the users.
- Perplexity’s Sonar Pro API powers the core processes like Claim Segmentation, Fact Analysis, Source Ranking.
- React frontend delivers a responsive UI with dark/light mode, claim breakdowns, and KPI cards (True/False/Misleading/Unverifiable), Source evidence excerpts,
- The feed leverages Sonar Pro’s image extraction, and multiple images are used as part of social networking feed
Challenges we ran into
- choosing the right news provider api was initially tough & time consuming needed a lot of R&D on similar tools.
- Implementing text highlighting for source excerpts faced cross-browser compatibility issues,
Accomplishments that we're proud of
- Built a scalable fact-checking platform powered by Sonar Pro’s real-time web search.
- Developed a tier-based source ranking system with authenticity and tonality metrics, enhancing transparency in source evaluation.
- Implemented seamless text highlighting for source excerpts, improving user experience by reducing manual search time.
- Created a collaborative feed with Sonar Pro-extracted images, driving community engagement and trust in shared reports.
What we learned
- We learned to optimize large-context API integrations like Sonar Pro for cost and performance, balancing real-time data needs with system efficiency.
- Navigating compliance requirements deepened our understanding of data privacy in user-driven platforms.
What's next for Fact Analyzer Platform
- Implementing custom models & algorithms for source verification & ranking
- expanding personalization with AI-driven topic recommendations, and supporting additional languages using Sonar Pro’s multilingual capabilities
- We plan to introduce real-time collaboration tools for users to co-analyze articles, enhance the feed with sentiment-based filtering, and optimize image compression for faster load times.
