Fact Check Analyzer

An AI-powered fact-checking application that verifies true/false claims against evidence using a two-stage AI pipeline — a guardrail classifier and a fact-check analyzer — with file upload support (PDF, CSV, DOCX, Markdown), DB-level caching, token tracking, rate limiting, a spending guard, cloud provider abstraction with model rotation, and an MCP server for tool integration. Built at Economic Data Sciences as a reference implementation for AI pipeline patterns — demonstrating how to architect production-grade AI applications with provider abstraction, multi-model rotation, cost controls, file processing, and tool integration via MCP.
