LangChain RAG

Problem

AI can't answer questions about your company's documents, policies, or internal knowledge. Most RAG tutorials are oversimplified—they work in demos but fail with real documents or at scale.

Solution

A production-ready pipeline that lets you ask questions about your own documents.

• Ingest a folder of documents (PDF, TXT, MD)
• Automatically chunk and index
• Ask natural language questions
• Get answers with source citations

Demo

Point it at your policy documents. Ask "What is the refund policy for enterprise customers?" Get an accurate answer with a citation showing exactly where it came from.

Run it
