I will build a rag ai chatbot with langchain and gpt for your data

Are you tired of basic chatbots that can't answer from your own data, documents, or product knowledge?

I will build a RAG AI chatbot using LangChain and GPT chatbot technology trained directly on your business documents, PDFs, website content, or FAQs. Unlike generic chatbots, this RAG chatbot retrieves real answers from your data using semantic search and a vector database, so it never hallucinates or guesses.

What you get:

RAG AI chatbot built with LangChain chatbot framework

Trained on your PDFs, docs, URLs, or knowledge base

Vector database setup Pinecone, ChromaDB, or FAISS

OpenAI GPT-4 or DeepSeek as the LLM backbone

AI assistant embedded in your website or app

Source code + full deployment support
