FactFlow

The production App for the PDF Fact-Check Analysis platform. Built with Django, Python 3.13, and PostgreSQL, optimized with a stateless architectural design.

Key Architecture Features

• Stateless PDF Processing: Zero physical storage writes for uploaded documents to guarantee enterprise-level data privacy.
• Concurrent Fact-Checking: Leverages multi-threading with optimized minimal thread pools to process extracted claims in parallel.
• Automated Live Search: Integrates with concurrent search endpoints to cross-reference statements across web indices dynamically.

    D --> E[4. Garbage Cleanup]
