Step by Step Build an n8n Website AI Agent Chatbot That Reads Your Site

🚧 Build a fully working AI chatbot for your Shopify store in one session—no complex frontend needed. We use n8n’s AI Agent, OpenAI (GPT-4.1 mini), and a Tavily web scraper to handle product Q&A and policies, then embed it via n8n’s official chat widget directly into theme liquid. You’ll learn API setup, memory, domain-restricted scraping, prompt design for conversion, and Shopify integration. We also cover testing, troubleshooting broken links, and next-step upgrades like RAG with Supabase/Postgres and CRM handoffs. What you’ll learn Create an n8n workflow with AI Agent + OpenAI API key & billing Add session memory and when to move to persistent memory (Supabase/Postgres) Configure Tavily for domain-restricted scraping of your catalog & policies Enable public chat, grab the embed snippet, and inject it before theme liquid Write a conversion-aware system prompt (tone, examples, link handling) Test queries (products, shipping) and handle edge cases Resources mentioned n8n AI Agent & Embed (public chat URL + JS snippet) OpenAI API Keys & Billing credits Tavily API (free monthly credits) Optional: Supabase/Postgres for persistent chat history + CRM (e.g., ActiveCampaign) If you want the starter template or the clickable-link fix for responses, comment “TEMPLATE” below and I’ll share it. ⏰Timestamps ================================================ 00:00 – Intro, plan & tooling (n8n, OpenAI, Tavily, Shopify) 01:00 – Build the n8n workflow: AI Agent, OpenAI keys, billing credits 03:20 – Add memory + Tavily scraper, restrict to your Shopify domain 07:55 – Enable public chat & embed widget into theme.liquid 10:45 – Live testing: product discovery, policies, prompt improvements 18:45 – Next steps: RAG (Supabase/Postgres), lead capture, CRM handoff & wrap-up #Shopify #AIChatbot #n8n #OpenAI #Ecommerce #Automation #NoCode #WebScraping #Tavily #ShopifyDev #RAG #Supabase #Postgres #LeadGen #CX 🔗 Tools I recommend for Automation & Ecom ================================================ N8N Affiliate: https://n8n.partnerlinks.io/y101dgxkiu9o Debutify AI Theme: https://www.debutify.com/theme Shopify: https://shopify.pxf.io/c/2789899/1101...
