An AI agent that watches your Facebook posts & ads, replies to comments, answers DMs, and closes sales in Messenger — while you sleep.
When a business runs a Facebook post or an ad campaign, the comments start coming in fast. People ask about price, availability, delivery, features — and they expect a reply within minutes. Not hours.
But most business owners can't sit in front of their screen all day. And hiring someone just to reply to Facebook comments is expensive and still not fast enough. So leads wait. Some of them lose interest and buy from a competitor. Sales that could have been closed in 10 minutes turn into lost opportunities.
I saw this problem and built something that handles the entire conversation — from the first comment to the final sale — without the business owner touching anything.
The moment someone comments on a Facebook post or a running ad, the AI agent jumps in. It reads the comment, understands what the person is asking, and posts a relevant, personalized reply right there in the comment section.
But it doesn't stop there.
It also opens a Messenger conversation with that same person and starts a proper chat — greeting them, answering their questions about the product or service using the actual business information and campaign details, and guiding them toward making a purchase.
The AI isn't giving generic answers. It's pulling from the business database, so it knows the product, the pricing, the offers, and the common questions — and it responds like a trained sales rep would.
When a sale is closed inside Messenger, the agent automatically updates the sales record in Google Sheets and sends the business owner a notification so they always know what's happening without having to check manually.
A business can now run a Facebook campaign and go about their day knowing every single comment is getting a reply, every interested person is getting a proper conversation, and every sale is being recorded — all automatically.
The response time goes from hours to seconds. Leads don't go cold. Sales don't fall through the cracks. And the business owner's time is freed up completely for things that actually need their attention.
Built with n8n for the automation backbone, connected to the Facebook Graph API for comment and Messenger handling, AI language model for understanding and generating responses, and Google Sheets as the sales database with instant notifications to the owner.
If you're running Facebook ads or managing a business page and you're tired of losing leads just because you couldn't reply fast enough — this is exactly what you need. It doesn't replace your brand voice, it becomes your brand voice, available 24/7.
