I will build a custom AI Chatbot or Agent using RAG (LangChain / LlamaIndex)

Get a custom, production-grade conversational AI chatbot or multi-agent system powered by LLMs (OpenAI, Gemini, Claude). I implement Retrieval-Augmented Generation (RAG) using LangChain and LlamaIndex to allow the chatbot to search and retrieve information directly from your internal company knowledge bases (PDFs, Notion, SQL databases, API endpoints).

What's included:
- Custom system prompt engineering and conversation flow design
- RAG pipeline integration with vector databases (Pinecone, Chroma, pgvector)
- Deployment-ready API or simple UI widget integration
- 100% data security and conversational control filters
