I’m building an AI agent that will live on my website and act as the first-line customer-support rep for visitors with technical questions. The bot must understand and respond to troubleshooting queries in natural, conversational language, draw from our existing knowledge-base or API endpoints for accurate answers, and seamlessly escalate anything it can’t resolve to a human ticketing queue. Here’s what I need from you: • Design and train an NLP model (open-source LLM fine-tuning or a reliable third-party API—your recommendation is welcome) focused exclusively on technical support scenarios for my product. • Develop the chat interface and embed it on the site with clean, responsive front-end code. • Set up backend logic that pulls relevant docs, FAQs, and user account data so replies are personalized yet secure. • Implement a simple intent-confidence threshold that triggers hand-off to live agents via our existing help-desk system. • Provide clear documentation and a handover session so I can maintain and expand the model myself. I’m comfortable with popular stacks like Python, Node.js, or serverless functions—choose the approach that best fits quick iteration and future scaling. Let’s create something that reduces my support load and delights users from day one.
