I will build a rag chatbot for business documents
Zahid
About this gig
Need a chatbot that answers questions from your business PDFs, policies or manuals?
I build custom Retrieval-Augmented Generation (RAG) chatbots that search your content and generate grounded answers. Source citations can help users verify information in the original documents.
I can build:
- PDF and document question-answering
- Business knowledge-base assistants
- Chat interfaces
- Source references and fallback when information is missing
- Python APIs or website integration (package dependent)
Tools include: Python, LangChain or LlamaIndex, OpenAI, Claude or Gemini APIs, and vector stores such as FAISS, Chroma or Pinecone. Ill select the stack to fit your scope.
You receive the agreed chatbot, source code, setup instructions and testing using sample questions. Document limits, interface and deployment depend on the package.
Important: RAG retrieves information from your content; it does not fine-tune or retrain the AI model. API usage, hosting, OCR for scanned files and third-party subscriptions are not included unless agreed.
Message me before ordering with your document types, approximate volume and target platform so I can confirm the right scope.
