AI Taxi Booking Chatbot

I’m ready to add an AI-powered chat experience to my custom-built website (JavaScript front end with a .NET back end). The goal is simple: guide visitors through a short conversation that captures three things—pickup address and contact details, destination and any special instructions, and the pickup time—then pass that data straight into our existing order-processing logic. You’re free to recommend whether Google Gemini, OpenAI’s ChatGPT, or another LLM is the smartest choice for this workflow; I’m interested in hearing pros, cons, and any cost or latency considerations. Whichever model we use, I’ll need the chat widget embedded without disrupting current pages or load times. Key deliverables • Conversational flow design and prompt engineering for the three data points above • Front-end chat widget (JS/HTML/CSS) and posting tthrough an API • Validation and error-handling so incomplete or ambiguous answers are re-asked gracefully • End-to-end test cases showing data posted into our staging environment • Flexibility to alter the model in the future Success is the chatbot going live on our production site, reliably collecting those booking details, and handing them to our back-end exactly as if a user had filled out a form. If this sounds straightforward, let’s get started.
