One agent, set up once

Give it what you know, then place it

A CommentWatchDog AI agent is what your business knows and how it speaks, set up once. You place the same agent on the comments under your posts and ads, on your Instagram and Messenger DMs, or both. It answers only from your sources, in the customer’s language, and leaves what it does not know to a person.

  1. 01

    Give it what you know

    Paste a link to your pricing or FAQ page, drop in a PDF, add the questions people ask most. Or tell Build with AI about your business and it sets the agent up as you talk.

    You see exactly what it kept

  2. 02

    Try it before anyone sees it

    The preview beside the editor answers as the real thing would, as a comment or as a message, with what is on screen right now.

    1 AI credit a try, never posted

  3. 03

    Place it where people ask

    An agent answers nothing until you place it: on comments, on messages, or both. Start with drafts you approve.

    One agent, as many places as you like

  4. 04

    Teach it what it missed

    A question it could not answer waits on its page. Answer it once and the next person who asks gets that answer in seconds.

    The most asked sit at the top

Where it answers

One agent, two places

An automation puts the agent to work on a page: on comments, in messages, or both. Both come with every plan from Starter.

Comment moderation

Under your posts and ads

It reads each new comment, decides whether it is a question to your business, and writes the answer from what you gave it. Spam never reaches it: your moderation rules run first.

Any questionKeywords
Every comment that needs an answer, or only comments with your words. Thanks, emoji, tags and spam are left alone, and a reply you wrote yourself still goes first.
Write a draft for meReply by itself
Start with drafts: each reply waits on its comment in your comment inbox until you send it, edit it or throw it away. Switch when you trust them.
Needs reply
When it does not know, the comment is marked Needs reply and waits for you. Nothing is charged.
Let your AI agent answer comments, in the app

DM automation

In your Instagram and Messenger DMs

It answers the messages no keyword automation or welcome claimed first, or one question in the middle of a flow. Every DM setting is on the AI chatbot for DMs page.

Let your AI agent answer messages
One recipe turns it on: every DM nothing else answered gets a draft or an answer, with a cap per day and your hours if you want them.
AI agent answers
A step in the flow builder: one answer to what they last wrote, or a conversation towards a goal, then the flow goes on. When it sends nothing, its ways out say why: they want a person, it didn’t know, or it didn’t run. See the AI agent step.
Hand to a person when
They ask for a human, the agent is not confident, or they say one of your words. The chat waits in the Live inbox and the agent stays quiet there.
What you set

Every setting, in the app’s words

The same labels you will see in the app, what each one does, and the limit behind it.

What it knows

One Knowledge list per agent. Nothing is trained on it: what you add is what it answers from, and you can read every line.

Web pagePages from your website

Paste a link to your pricing, shipping or FAQ page. It is read once, rewritten as customer facts in the page’s own words, checked line by line against the page, and kept with its useful links.

Starter 3 pages, Growth 10, Pro 30, Elite no limit

PDF or documentFiles, even scans

A PDF, Word, Excel or PowerPoint file, text, CSV or an image: a catalogue, a policy, a price list. You see the text it pulled out and can correct it.

Growth and up, and on the trial. Up to 10 MB a file

TextYour own notes

Write or paste anything in your own words: prices, hours, delivery, what is included.

Questions and answersYour exact answers

The questions people ask most, with the answer you want given. An answer you wrote wins over anything a page or a file says.

Build with AISet it up in a chat

Tell the agent’s builder what you sell and paste your site. It reads it and fills the agent in as you talk. To have AI build a whole flow instead, see Build with AI for flows.

How it replies

Who it is, its voice and its rules. Facts go in Knowledge.

ToneFive voices

Helpful, Conversational, Professional, Casual or Funny. Each card shows how it would answer the same question.

Who it isA name and a role, if you want one

Leave it empty and it speaks as someone on your team, saying “we”. It always replies in the customer’s language.

RulesHow it answers, never what it knows

Short replies, no emoji, no delivery promises, their first name, the link in your bio, or rules of your own, one per line.

Try itA live preview

Ask it as a customer would, as a comment or as a message. It answers with what is on screen, saved or not, and nothing is posted or sent.

1 AI credit a try, up to 100 a day. A real answer uses 5

Correct thisFix an answer on the spot

Say what was wrong under a preview answer. It is saved where it belongs, as a question and answer, a rule or a correction in the source, then asked again.

Which comments count as questionsThe question check

Written by AI from what the agent knows and rewritten when its knowledge changes. Type your own wording to take it over.

Used when an automation answers Any question

On comments

The recipe Let your AI agent answer comments, on Instagram and Facebook, on every post, ads only, posts only or the posts you pick.

Any questionWhich comments

Any question answers every comment that needs an answer. Keywords answers only comments with one of your words. Answer every comment, not only questions replies to thanks and compliments too.

Write a draft for meDraft or reply

A draft waits on the comment until you send it. Reply by itself posts under the comment, and you see every one in the inbox.

A reply is up to 500 characters

Add a fallback agentA second agent, then you

When the first agent does not know, a second one gets one try. If nobody knows, the comment is marked Needs reply and waits for you.

You pay for one answer, whichever agent writes it

Limit replies per dayA ceiling for a post that goes viral

50, 200, 400 or 800 replies a day. Past it, comments wait in Needs reply.

Skip some commentsWhat it leaves alone

Comments that are only a tag, only emoji, replies inside another comment’s thread, or that have one of your words.

GenerateOne reply, when you ask

In the comment inbox, Generate writes the reply in the composer from the same knowledge, for you to edit and send.

5 AI credits

In DMs

The recipe Let your AI agent answer messages, or a step in a flow. The AI chatbot for DMs page goes through each setting.

Support agent on messagesEvery DM nothing else answered

The agent answers the Instagram and Messenger messages that no keyword automation or welcome claimed first.

One automatic answer per message

Draft for a person to sendDraft or answer

The agent writes the reply and it waits in the thread until someone sends or edits it, or it answers at once.

Each answer or draft uses 5 AI credits

Hand to a person whenThree ways to a person

They ask for a human, the agent is not confident, or they say one of your words, such as refund, complaint or cancel.

AI agent answersA step in a flow

One answer to what they last wrote, or a conversation that works towards a goal and saves what they tell it. Then the flow goes on.

Four ways out. Nothing is sent on Wants a person, Couldn’t answer or Didn’t run

Notify the teamYou hear about it

A notice when the agent hands over, or on every answer.

When it does not know

It never guesses. It asks you

Before an automatic answer goes out, a second check lists every business fact in it and confirms your sources state each one. One fact it cannot find, a denial included, and the answer is held for a person.

Left to you on purpose
An upset customer, refunds and wrong charges, health, legal or safety matters, abuse, and personal details posted in public get no automatic reply.
Unanswered
Every question it could not answer, from comments and from messages, waits on the agent’s page. Answer one and it becomes a question it knows.
Out of AI credits
It stops answering and the comment or the chat waits for a person. Nothing else stops.
Unanswered, on the agent’s page
In the app

One screen, the preview beside it

How ready it is and Knowledge on the left, the live preview on the right. An agent you have created adds two tabs: Unanswered and Where it answers.

Questions

Questions about AI agents

Short answers before you create one.

Yes. Place an agent on your comments and it answers the questions under your posts, reels and ads from what you gave it, on Instagram and Facebook, through Meta’s official API. It can write a draft for you to send, or reply by itself. Thanks, emoji, tags and spam are left alone.

Yes. An agent is what your business knows and how it speaks; an automation decides where it answers. The same agent can answer comments, Instagram DMs and Messenger chats, and a question it learns in one place it knows in the other. The AI chatbot for DMs page covers the DM side.

It answers only from your knowledge. Before an automatic answer goes out, a second check lists every business fact in it and confirms your sources state each one. If one is not there, a denial included, the answer is held and the question goes to a person.

Pages from your website (one link per page), text you write or paste, your most common questions with their answers, and from Growth, files such as PDFs, Word, Excel and PowerPoint documents and images. The knowledge is placed in front of the agent for each answer; no model is trained on it.

Anything its knowledge does not answer, and five subjects on purpose: an upset customer, refunds and wrong charges, health, legal or safety matters, abuse, and personal details posted in public. On a comment it marks Needs reply; in a DM the chat waits in your inbox and the agent stays quiet there.

Yes. It replies in the language the customer wrote in, whatever language your knowledge is in.

Start with drafts. On comments the reply waits on the comment, and in DMs it waits in the thread, until you send, edit or discard it. Switch to automatic replies once the drafts read the way you would write them.

Starter includes 1 agent, Growth 3, Pro 10 and Elite has no limit. Each answer or draft uses 5 AI credits from your plan’s monthly pool (1,000 on Starter); a question it could not answer costs nothing, and a try in the preview costs 1. See pricing.
