In this video, I’ll walk you through building a smart lead-capturing chatbot using the power of AI (ChatGPT / OpenAI APIs) combined with FastAPI, Socket.IO, and SQLite.

Unlike traditional rule-based bots, this chatbot understands natural language, detects whether the user is interested in your services, and — if they are — politely collects their name, email, and phone number for follow-up.

This is a perfect solution if you’re looking to automate lead generation on your website without complex CRM tools.
