ProposalGuard: Grounded AI Proposals with LangGraph
The hallucination problem in AI-generated proposals: polished
output, fabricated claims. ProposalGuard solves it with a 5-node
LangGraph pipeline. Every claim verified against retrieved context,
bias scanned, human-in-the-loop approval before anything ships.
Loom walkthrough: https://www.loom.com/share/41ee4b1157bb4192bc97c20240824a3b
Stack: Python, FastAPI, LangGraph, ChromaDB, Claude API, Next.js, TypeScript.
