Website AI Customer Support Chatbot

I need a lightweight, AI-powered chatbot that can sit on my website and answer visitors’ questions in real time. It should draw its responses from a FAQ or knowledge-base file I will provide, cover the usual queries about our products and services, and keep the tone friendly and helpful. The interface must be clean, intuitive, and easy to embed with a single script or iframe so I can drop it straight into an existing page for a quick demo or full production use. To keep things simple, no user login is required—just a conversational widget that greets the visitor and responds accurately. Fast response times and graceful fall-backs to a “contact us” prompt when the bot is uncertain are important. You’re free to use the tooling you prefer (Dialogflow, Rasa, LangChain, or a lightweight custom approach) as long as the final package includes: • A working web-based chat widget styled to blend with any modern site • Backend logic that reads my FAQ/knowledge base (markdown, CSV, or JSON) and returns relevant answers • Clear instructions for updating that knowledge base and redeploying • A brief hand-off document covering installation steps and any API keys or environment variables required Once the bot reliably covers the top questions and I can embed it on a test page without extra effort, the project will be complete.
