Build a website AI chatbot with lead capture using Gemini and Supabase RAG

This workflow deploys a fully customizable AI chatbot that can be embedded on any website, from custom-coded sites to platforms like WordPress. The chatbot is powered by n8n, uses Supabase for memory and RAG, and integrates SerpAPI, Google Calendar, SMTP, and Google Sheets to automate responses, collect leads, and follow up intelligently.

Unlike typical widgets, this bot captures name and email before chatting, enabling personalized, human-like conversations and smart lead tracking. Check [demo here](here)
