I will build an ai chatbot with rag langchain and openai

Want a chatbot that answers from your own PDFs, website and documents, and doesn't make things up? I build AI chatbots with RAG (retrieval-augmented generation), LangChain and OpenAI that give accurate answers and show where each one came from.

I'm a full stack developer with 4+ years of experience building AI chatbots and agents with Python, LangChain, LangGraph and FastAPI. My own RAG assistant answers questions from PDFs and web pages, and falls back to a web search when the documents don't have the answer.

What your chatbot can do:

- Answer questions from your PDFs, web pages and documents

- Show the source of each answer

- Say "I don't know" instead of guessing

- Remember the conversation

- Work through a clean web chat interface

- Use a vector database for fast, accurate search

What you get:

- A tested chatbot trained on your content

- Clean Python code you own

- A short guide on how to add new documents

- Support after delivery

Message me about your documents and what you want the bot to answer, and I'll tell you honestly which package fits.
