I will build an AI chatbot that answers your customers from your documents

About this service

I help small teams turn scattered documentation into a useful customer-support chatbot. I build the retrieval and answer flow in Python with FastAPI, LangChain or LangGraph, a vector database, and the LLM provider that fits the project. The chatbot can answer from PDFs, help-center pages, product documentation, or internal knowledge, cite the source passages, refuse unsupported questions, and hand off uncertain conversations to a human. My process is simple: review your content and the questions customers ask, define the answer and escalation rules, build the ingestion and retrieval pipeline, connect the chat channel, then test it against a real evaluation set. I have built hybrid RAG and GraphRAG systems using vector, full-text, and graph retrieval with reranking, as well as multi-channel conversational systems. You receive a working first version, setup notes, test cases, and a clear path to update the knowledge base.

What Phan needs from you to start

Please provide: 1) the documents or help-center links the chatbot should use, 2) 10–20 real customer questions with the preferred answers, 3) the channel for the first version, such as a website widget or Telegram, 4) your preferred LLM or hosting constraints if you have them, and 5) the success criteria, for example citation accuracy, response time, or escalation behavior. Never send passwords or private API keys in chat; use a secure handover method for credentials.
