Auto Reply
Facebook Marketplace Auto Reply
How to set it up, and when you need an AI agent. By Julien Benaggoune, founder of PilotAgent. Last updated: October 2026
Short answer: you can auto reply on Facebook Marketplace in two ways. Facebook's own Meta AI reply is free: switch it on when you create a listing and it answers "Is this still available?" from your listing details. For everything after that first question, an AI agent such as PilotAgent answers the whole conversation for you: follow-up questions, price, contact details and viewing times. It runs as a Chrome extension in your own Messenger, with no Meta API approval needed.

How to turn on auto reply on Facebook Marketplace
Facebook's built-in Meta AI reply (free)
- Start a new listing on Marketplace.
- Switch on the Meta AI reply option while you fill it in.
- Preview the reply, edit it if you like, and publish.
It answers availability questions from your listing details. Facebook added it in March 2026 and it may not be in every country yet.
PilotAgent, an AI agent for the whole chat
- Add the PilotAgent extension to Chrome and create your account.
- Tell the agent about your listings, prices and rules.
- Open Facebook Messages. Buyers get answers while your computer is on.
Answers every message, not just the first. Most sellers are replying the same day.
Auto reply vs an AI agent: what each one can do
There are three routes to automating your Facebook Marketplace replies. They are not equal, so here is the honest comparison.
| Capability | Meta AI built-in | Saved replies | PilotAgent |
|---|---|---|---|
| Answers “Is this still available?” | |||
| Answers follow-up questions | |||
| Negotiates within a floor price | |||
| Captures name and phone number | |||
| Arranges viewings and test drives | |||
| Replies in the buyer's language | |||
| Works across multiple accounts |
Meta AI's built-in reply is free and worth switching on if you sell casually. It answers the availability question from your listing details, then the rest of the conversation is up to you. Saved replies need a business page and still fire the same canned text at everyone. If your income depends on Marketplace, the conversation after the first message is where the money is.
What PilotAgent's auto reply actually does
Fast, natural replies
Buyers get an answer while they are still looking at your listing. Fast first replies are the biggest factor in whether a buyer shows up.
Negotiates within your rules
Set a floor price per listing. The AI fields lowball offers, counters politely, and holds your line while you do something else.
Captures every lead
Names and phone numbers are pulled out of conversations and filed into a built-in CRM automatically. No more scrolling Messenger to find that buyer from Tuesday.
Arranges viewings and test drives
The AI suggests times from your hours and agrees a viewing or test drive in the chat, so interested buyers commit before they cool off.
Covers the night shift
Most Marketplace messages arrive evenings and weekends. While your computer is on, the AI answers them and you come back to answered buyers and saved leads, not a backlog.
You stay in control
Pause the AI on any single conversation and take over yourself. Resume when you want. Every reply is visible in your dashboard.
Set up auto reply in three steps
- 1
Install the Chrome extension
No Meta API approval, no business verification, no developer account. It runs in your own browser alongside your normal Facebook session.
- 2
Tell the AI about your listings
Set the tone, the facts buyers ask about, and a floor price for negotiation. Takes a few minutes per listing, or set defaults for everything.
- 3
Let it answer
The AI replies to every new message at a natural pace, evenings and weekends too while your computer is on. Leads land in your dashboard CRM. You can take over any chat with one click.

High-volume sellers
Resellers and service businesses running many listings, or many accounts, from one dashboard.
Facebook Marketplace auto reply FAQ
How do I turn on auto reply on Facebook Marketplace?
For simple questions, switch on Meta AI's reply when you create a listing. Facebook then answers "Is this still available?" from your listing details. To answer the whole conversation, including price, viewings and contact details, install an AI agent such as PilotAgent, a Chrome extension that replies in your own Messenger.
Is Facebook Marketplace auto reply free?
Meta's built-in AI reply is free and answers availability questions only. PilotAgent starts at $10 per month for 1,000 AI replies, and Starter and Professional come with a 7-day free trial.
What is the difference between auto reply and an AI agent?
An auto reply sends one answer to one kind of question. An AI agent reads each buyer's message and holds the whole conversation: it answers follow-up questions, negotiates within your rules, asks for contact details and suggests viewing or test-drive times, the way you would.
Is it safe to use an auto reply tool?
PilotAgent works through a Chrome extension in your own browser, replying inside your normal Messenger session at a human pace. It never asks for your Facebook password and only answers buyers who messaged you first. You can pause it on any conversation. Read the full answer on account safety.
Do I need Meta API approval?
No. PilotAgent runs as a Chrome extension, so there is no developer approval, no business verification and no waiting.
Do I need to keep my computer on?
Yes. PilotAgent runs in Chrome on your computer, so it replies while your computer is on and Facebook Messages is open. Many sellers leave an old laptop running. Ask us about a hosted option that runs around the clock (a paid add-on).
Can the auto reply negotiate price?
Yes. You set a floor price and negotiation style for each listing. The AI handles lowball offers, counters politely, and does not go below the limit you set.
Does it reply in other languages?
Yes. PilotAgent replies in the language the buyer writes in, or in a language you choose.
How much does it cost?
PilotAgent starts at $10 per month for 1,000 AI replies. Professional is $20 for 4,000, Enterprise is $50 for 10,000 with webhooks and CRM sync, and Enterprise+ starts at $149 with custom limits. Starter and Professional come with a 7-day free trial.
