Most businesses lose leads due

Most businesses lose leads due to slow response. I built a full-stack AI lead capture system that replies within 60 seconds—automatically, 24/7. A mobile-first Next.js page captures leads, while an 8-node n8n workflow logs data to Google Sheets, sends WhatsApp alerts, generates personalized replies via Gemini API, and emails via Gmail. Each step updates lead status in real time. Costs <$1 per 100 leads. Easily customizable via one constants file. Built with Next.js 14, TypeScript, n8n, Gemini API, Twilio, Google Sheets API.
