WhatsApp AI Chatbot (GPT-4o + n8n Integration)

smart, human-like responses on WhatsApp—automated 24/7.

This plug-and-play chatbot system lets you deploy an AI assistant on WhatsApp that can hold real conversations, answer questions, and even remember past interactions—all using GPT-4o, LangChain, and n8n.
