Facebook Page AI Agent
AI-powered customer support agent for Facebook Pages that answers inquiries, filters duplicate messages, and responds using your knowledge base.

The Problem
Managing customer inquiries on a Facebook Page manually meant slow response times, missed messages during off-hours, and repetitive answers to the same questions.
The Solution
Built an n8n agent connected to Facebook Messenger via webhooks. It filters duplicate messages to avoid double replies, queries a Page Knowledge Base for accurate information, and uses Google Gemini to generate natural, context-aware responses. The agent maintains conversation memory so interactions feel continuous rather than robotic.
Key Outcomes
- Instant responses to customer inquiries 24/7
- Duplicate message filtering prevents spam replies
- Knowledge base integration ensures accurate answers
- Conversation memory for natural, contextual replies
