24/7 Customer Support & Booking AI Agent

Most businesses lose leads because they respond too late. After-hours inquiries, pricing questions, and booking requests go unanswered until the next business day — by then, prospects have already moved on to a competitor who replied faster.

An 8-node n8n AI agent named 'Jarvis' that never sleeps. It uses OpenAI for conversation, Supabase for persistent memory, semantic search over a knowledge base for accurate answers, and Gmail to automatically book discovery calls or escalate complex concerns to human support.
