Multi-agent AI (LangGraph) to audit AI papers for reproducibility

PaperPulse is a browser-integrated, multi-agent AI system that automatically audits scientific papers, news articles, and web content for methodological rigor, statistical validity, and code-to-paper alignment.

Unlike generic "Chat with PDF" wrappers, PaperPulse orchestrates specialized AI agents to cross-reference claims, search GitHub for official repositories, and flag reproducibility gaps with exact citations.
