I need an AI-driven chatbot embedded directly in my shopping website’s chat widget to handle customer support and field everyday general inquiries. The goal is for visitors to receive fast, accurate answers 24/7 without leaving the site. My current stack is a typical e-commerce front end (HTML/CSS/JavaScript) with a PHP back end, so the bot must slot neatly into that environment. I will provide my existing FAQ, product catalog, and policy documents; your task is to fine-tune the underlying model on this material so replies stay brand-consistent and correct. I’m open to proven frameworks—OpenAI API, Dialogflow, Rasa, or a similar NLP toolset—as long as it delivers reliable intent detection and a simple hand-off to live agents when needed. Key deliverables • Fully integrated website chat widget connected to the chosen NLP service • Custom training/knowledge base built from my content, ready for ongoing updates • Clear documentation on how to retrain, add intents, and monitor conversation logs • Short user test showing it can answer at least 90 % of common questions correctly If there’s a clean path to later expand the bot to order tracking or social channels, flag that in your proposal, but for now the focus is rock-solid on-site customer support.
