Mentbot VS ManyChat

Mentbot's answer

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:

• No flow builder and no per-post setup. You set one rule for the page and every future matching post is covered automatically, so a post published at midnight is automated because it exists.
• Features built for selling in comments, not for marketing funnels: automatic comment hiding so competitors cannot poach your buyers, replies to image and sticker comments, and alerts when a Messenger conversation goes unanswered.
• Flat pricing by daily comment volume with every feature on every plan and unlimited Facebook pages, so a viral post never pushes you into a more expensive tier.

Mentbot's answer

Pick Mentbot when comments are your sales pipeline and you want that fixed today rather than after building funnels.

• Five minutes to full coverage. No visual flow editor to learn and no attaching triggers to individual posts. Platforms like ManyChat and Chatfuel are more powerful overall, but that power costs setup time you may not want to spend.
• Nothing gets forgotten. Page-wide rules mean every future post is automated by default, which matters if you publish product content daily.
• Predictable cost. Flat monthly pricing by daily comment volume instead of per-contact billing, so a post that goes viral does not increase your bill.
• A human closes the sale. Mentbot opens the Messenger conversation, then alerts your team when a reply goes unread — because in comment-selling the close rate lives in fast human follow-up, not deeper automation.

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.

Mentbot's answer

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:

• Online sellers and small e-commerce brands running daily product posts, live selling, or CF-style ordering, who lose buyers when a comment sits unanswered for an hour.
• Small teams and page admins who cannot staff the inbox 24/7 and need every late-night commenter answered and followed up.
• Anyone paying for reach with ads or content who wants the resulting comments captured instead of leaking to faster competitors.

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's answer

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's answer

Mentbot is a TypeScript codebase running on Node.js, built as a monorepo:

• Website — Astro, with Tailwind CSS
• Dashboard — Next.js and React
• API — ElysiaJS
• Background jobs — BullMQ with Redis, which handles the comment webhooks and reply queue
• Integration — Facebook Graph API (Pages and Messenger), using permissions granted by the page owner

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.
