Project details
You will get a fully functional RAG (Retrieval-Augmented Generation) system that lets your team chat with your documents using AI. I specialize in building production-grade knowledge bases using LangChain, OpenAI, and vector databases like Pinecone or Chroma. Whether you have PDFs, Word files, internal wikis, or URLs — I will ingest, embed, and make them searchable through a conversational AI interface. Unlike generic chatbots, RAG systems answer from your actual documents, reducing hallucinations and keeping answers grounded in your data.
