Facebook AI Agent
Messenger replies, page comment responses, and lead capture — automated on Meta's official API.
Why Your Facebook Page Needs an AI Agent
Your Facebook business page generates messages and comments all day — questions about prices, availability, and orders. When replies take hours, customers move on to a competitor, and your page's response-rate badge suffers.
How the Facebook AI Agent Solves It
Neksio's Facebook AI agent connects to your business page through Meta's official API and answers Messenger conversations and page comments instantly. Powered by RAG on your own business knowledge, it sells, supports, and captures leads 24/7 — with human handoff when it matters.

What a Facebook AI agent does on your Page
A Facebook AI agent answers the people who message your Facebook Page on Messenger, and replies to the questions they leave in your Page and ad comments. It reads each message, understands what the customer wants, and answers in plain language from the business knowledge you give it — prices, stock, delivery times, opening hours, policies.
Because Neksio uses retrieval-augmented generation (RAG), the agent looks up the relevant passage in your own documents before it replies. If the answer is not in your knowledge base, it says so and leaves the conversation in your inbox for a person, instead of inventing something your team then has to correct.
Messenger replies, comments and click-to-Messenger ads
Most Facebook enquiries arrive in three places: direct Messenger chats, comments under your posts, and conversations started from click-to-Messenger ads. The ad conversations are the most expensive to miss — you paid for the click, and a customer who waits hours for a reply rarely comes back.
The agent answers all three within seconds, at any hour. A public comment asking "price?" gets a helpful reply, and buyers are moved into a private Messenger conversation where the agent can answer properly, ask for contact details and pass qualified leads to your team.
Fast, consistent replies also keep your Page's responsiveness high, which is one of the first things a new customer sees when they open your Page.
Built on Meta's official Messenger Platform
Neksio connects your Page through Meta's official Messenger Platform and webhooks, so there is no unofficial automation touching your account. Unlike WhatsApp, Facebook Pages do not need a separate business verification step, so most businesses can connect a Page and go live the same day.
The same agent can also answer on WhatsApp and Instagram from one knowledge base, and every conversation lands in a single inbox. You or your team can take over any chat at any point, from the browser or the Neksio Android app.

Facebook AI Agent FAQs
What can a Facebook AI agent answer?
+
Anything covered by the business knowledge you upload: product details, prices, availability, delivery and return policies, opening hours and FAQs. When a question falls outside that knowledge, the agent says so and leaves it for your team.
Does the agent reply to Facebook comments as well as Messenger?
+
Yes. You choose whether it handles Messenger chats, Page and ad comments, or both. Comment replies can move a buyer into a private Messenger conversation so the details are not discussed in public.
Is the Facebook AI agent built on the official API?
+
Yes. Neksio connects through Meta's official Messenger Platform, so your Page is not exposed to the risks of unofficial automation tools.
How long does it take to set up?
+
Usually minutes. Facebook Pages do not go through the business verification WhatsApp requires, so once your knowledge base is uploaded you can connect the Page and go live the same day.
Can I take over a conversation?
+
Yes. Every Messenger conversation appears in the Neksio inbox and Android app, and you can reply as a human at any time.
Which plan includes Facebook?
+
Facebook is on the Growth plan ($11.99/month), together with Instagram, TikTok, 15,000 AI replies and three team seats. The Free plan covers WhatsApp only.
