I need a conversational bot that sits on my website and returns precise answers pulled directly from my document collection. The focus is pure information retrieval—no sales pitches or account look-ups—so every feature you build should revolve around searching, parsing and presenting the right excerpts from those files. Here’s what I’m after: • A web-embedded chat interface that blends smoothly with my existing site design. • Back-end logic that indexes my provided documents (PDF, Word and similar formats) and makes them queryable in natural language. • Fast, relevant responses that quote or reference the source passage so the user can verify the answer. • An easy way for me to add, remove or update documents without redeploying the whole system. Acceptance will be based on: 1. Installing the bot on a test page of my site. 2. Demonstrating accurate retrieval from at least five sample documents I supply. 3. Proving that new uploads become searchable in under five minutes. You’re free to choose the stack—whether you lean on OpenAI, LangChain, RAG pipelines, Elasticsearch or another approach—so long as it delivers reliable, low-latency results on the website. Let me know what you’d use, how long it will take, and any hosting prerequisites I should prepare.
