Facebook Messenger AI Agent (n8n)
n8n agent that answers Facebook Page messages 24/7 using a Google Docs knowledge base and Gemini with session memory.
Problem
Small businesses miss leads and frustrate customers when Facebook Page messages go unanswered outside business hours.
Approach
Built a fully automated Facebook Messenger AI agent using n8n that receives incoming messages via webhook, pulls a custom Google Docs knowledge base as its memory source, processes the message through a Google Gemini AI model with session memory for context, and sends intelligent replies back through the Facebook Graph API, all without human involvement.
Outcome
24/7 AI-powered Facebook Messenger responses with business-specific knowledge and conversation memory.
