You will get custom chatbot for your docs using langchain and GPT | AI agents
Project details
Here's the trimmed version — exactly 1,198 characters:
Looking for an AI chatbot developer who can turn your docs into a smart assistant? I build custom GPT-4 chatbots using LangChain and the OpenAI API that give instant, accurate answers from your own content.
As a Python automation developer with deep AI tools development experience, I specialize in RAG pipelines that connect GPT-4 to your real business data. Need a chatbot for your website, an internal knowledge bot, or a full AI workflow automation system? I build it production-ready.
My prompt engineering expertise ensures the bot answers accurately — with source citations and multi-turn memory.
What you get:
GPT-4 chatbot trained on your docs (PDF, DOCX, URLs, Notion)
LangChain RAG pipeline with vector search & memory
FastAPI backend + chat UI (Streamlit or React)
Optional AI agent setup for AI automation developer workflows
Business automation AI with tool use & web search
Docker + cloud deployment, full source code & README
Let's build a chatbot that actually works.

They get a chatbot that sounds smart but doesn’t help customers.
Or automation that looks good but doesn’t save real time.

• Don’t connect AI to real workflows
• Deliver tools that are rarely used after setup
