n8n template #3859

Summary

AI Customer-Support Assistant that auto-maps any business site, answers WhatsApp in real time, and lets you earn or save thousands by replacing pricey SaaS chat tools. ⚡ What the workflow does Live “AI employee” - the bot crawls pages on demand (products, policies, FAQs) so you never upload documents or fine-tune a model. No-code setup - Drop in API keys, paste your domain, publish the webhook—ready in \~15 min. Chat memory - each conversation turn is written to Supabase/Postgres and automatically replayed into the next prompt, letting the assistant remember context so follow-up questions feel natural and coherent even across long sessions. WhatsApp ready - Free-form replies inside the 24-ho
