This page is designed to help you find out whether Mentbot is good and if it is the right choice for you.
Mentbot is Facebook comment automation for pages that sell in the comments. The moment someone comments on your post, Mentbot replies publicly and sends that commenter a private Messenger message at the same time — so every "how much?" becomes a conversation you can close, even at 2am.
Unlike general chatbot platforms, Mentbot is built for one job and takes about five minutes to set up. Connect your Facebook page, choose which posts to watch, write your two replies, and every future matching post is covered automatically. There are no flows to build and no per-post setup.

Built for selling in comments
Pricing
Flat monthly pricing based only on daily comment volume, from $9/month for 100 comments per day up to $49/month for 5,000. Every feature is included on every plan — the tiers differ only in volume and alert frequency. A viral post never moves you to a more expensive plan.
Every plan starts with a 14-day free trial, no credit card required, and you can cancel anytime.
Mentbot works through Facebook's official Pages API using permissions you grant, so private replies to commenters stay within Facebook's rules.

Mentbot does one job completely instead of being a general chatbot platform. When someone comments on a Facebook post, it posts a public reply and sends that commenter a private Messenger message at the same moment — turning a public comment into a private sales conversation in under a second.
Three things make it different from broader tools:
Pick Mentbot when comments are your sales pipeline and you want that fixed today rather than after building funnels.
Choose a full chat-marketing platform instead if you need multi-step conversational flows, drip campaigns, or Instagram and WhatsApp coverage. Mentbot is deliberately Facebook-only and rule-based.
Facebook page owners and admins who sell directly in the comments — where "how much?" under a product post is the start of a sale rather than idle engagement.
Typical users:
It fits businesses that want the comment problem solved in minutes rather than marketers who want to build conversational campaigns — that need is better served by a full chat-marketing platform.
Mentbot started with a simple observation: businesses lose sales every day because comments go unanswered.
Watching Facebook sellers work, the same pattern kept repeating. A product post gets fifty comments asking about price and availability. The admin answers them one at a time, hours later, copying the same reply and manually opening each private message. By then the buyer has already bought from a page that answered faster — or a competitor has messaged them directly from the public comment thread.
The existing tools were either too basic (Facebook's built-in automation, which applies to the whole page with no keyword control or reporting) or too heavy (full chat-marketing platforms that ask you to learn a flow builder and attach triggers to individual posts before anything happens).
So we built the middle: automation that replies to every Facebook comment, pulls the conversation into Messenger, and gives admins their time back — set up in about five minutes, with no flows to build. Mentbot is made by an independent software studio in Thailand, where selling in Facebook comments is a mainstream way to run a business.
Mentbot is a TypeScript codebase running on Node.js, built as a monorepo:
Fast, reliable queue processing is the part that matters most: replies need to go out within about a second of a comment arriving, and every plan has a daily volume to honour.
