WhatsApp with AI: broadcasts and reply templates written in an afternoon

WhatsApp with AI is a Tech and Skill job: a month of short broadcasts plus a set of saved replies, written by the AI you already pay for and sent from WhatsApp Business. Writing and loading it all takes an afternoon, and after that the work is a few minutes a day answering the people who write back. The AI writes; WhatsApp Business sends. You supply the facts, choose who hears from you, and answer the real conversations yourself.

The shape: Tech and Skill

This job is Tech first because the greeting, the away message and the quick replies are set up once and then work on their own. WhatsApp Business has its own tools for a business account: a profile, labels for sorting chats, quick replies you call up with a shortcut, a greeting message for first contact and an away message for after hours. Most of the afternoon goes into setting those up so the words have somewhere to live. If you have not switched from the personal app yet, start at WhatsApp Business and read what the free app does before you write anything.

It is also a Skill job because WhatsApp is a personal channel. Your message lands between a text from someone's sister and a photo from their friend. Writing for that spot is its own craft: short, plain, one point per message, and nothing that reads like an ad. The AI can learn that style quickly if you show it, and it can hold it across a month of messages better than you can on a busy Tuesday.

What that means for you: do the writing in one conversation with your AI, keep the results in one document, and then spend the second half of the afternoon on the phone, saving the replies and messages. Plan to send each broadcast yourself on the day it is due, so you read it once more before it goes.

What you give the AI

Gather these before you open the chat. Every gap you leave is a gap the AI fills with something it made up, and on WhatsApp a made-up price goes straight to a customer's phone.

  • The ten questions customers ask most. Copy them from your real chats, texts and emails, in the customer's own words. "Are you open Sunday?" passes. "General questions" fails.
  • The true answer to each one. Your hours, how booking works, delivery areas, what a deposit covers, how long a job takes. Only facts you can stand behind today.
  • The month ahead. Dates that matter to your customers: a holiday closure, a new item arriving, a booking window opening, a seasonal reminder.
  • Three messages you have sent customers before. Real ones, from WhatsApp or text, so the AI matches how you actually write to people.
  • Your audience in one sentence. "Parents who book swim lessons for kids under ten" passes. "Our customers" fails.
  • Your rules. What you never say, what you never promise, and how you sign off. If you already have a voice guide, paste it. If not, the brand voice guide job takes one sitting and pays off on every channel.
  • How people opt in and out. The sentence you use to ask for permission, and the word someone can send to stop hearing from you.

What comes back

Run this as one conversation. Paste the brief below and fill in the brackets. Read the first two broadcasts before you ask for the rest, and correct the tone in the chat if it misses.

You are helping a small business owner write WhatsApp messages.

The business: [what you do, where, for whom]
Audience: [one sentence]
Rules: [what we never say or promise, how we sign off]
Hours: [your opening hours]
How to stop messages: [the word customers send to opt out]

Messages the owner has sent before:
[paste 3]

Common questions and the true answers:
[paste each question, then its answer]

Dates that matter this month:
[paste each date and what happens]

Write, in this order:
1. A greeting message for someone who writes to us for the first time, under 40 words.
2. An away message for after hours, under 30 words, with our real hours.
3. One saved reply for each question above, under 50 words each, with a short shortcut name for each, like /hours.
4. One broadcast for each date above, under 60 words each. One point per message. Say what changed, why it matters to the reader, and one thing to do next. End each with how to stop messages.

Write the way the owner writes in the examples. Short sentences, plain words. No hashtags, no emoji unless the owner's examples use them, no exclamation marks, no urgency words like "hurry" or "last chance" unless a real deadline exists. Use only facts given above. Mark anything you are unsure of with [CHECK].

What comes back is plain text in four labeled parts. The greeting and away messages go into the Business tools section of the app. The saved replies go into quick replies, each under its shortcut, so typing the slash and the name brings up the full answer in any chat. The broadcasts stay in your document with their dates, ready to paste on the day.

When the month ends, come back to the same conversation. Paste the replies the broadcasts got, including the people who asked to stop, and ask the AI what landed and what to change next month. That loop, real reactions in and better messages out, is the skill getting sharper.

How to judge it

Read every message on your own phone, in WhatsApp, as if a business you barely know sent it. A bad result is easy to spot there.

A bad broadcast reads like an ad. If it opens with your business name, a headline in capitals or "Exciting news", it will be muted. A good one reads like a note from someone the customer knows: "We're closed Monday for the holiday, back Tuesday at 8."

A bad broadcast says two things. A message that announces new hours and a new product and a referral offer gets none of them read. Split it, or cut two.

A bad saved reply is long. If it scrolls past one phone screen, the customer stops reading, so ask the AI to halve it.

A bad saved reply is confident about something you did not give it. Search every draft for prices, dates, guarantees and discounts, and check each one against your own answers. An AI filling a gap will name a delivery fee or a refund window in a calm, certain tone, and the customer will hold you to it.

Bad urgency is a red flag. "Only today" on a message with no real deadline trains people to ignore you, and it is the kind of message that gets a business reported.

Last, search for [CHECK]. Fix or delete every one before anything goes into the app.

What stays with you

The AI writes and WhatsApp sends. Four parts of this job stay with you, and no AI does them.

Who hears from you. Message only people who agreed to hear from you, and keep a note of who said yes. WhatsApp's business policy sets out what it expects from businesses that message customers, and privacy laws where your customers live may ask for more. Ask regular customers to save your number in their phone, and read WhatsApp's help pages for the current rules on who receives a broadcast, because those rules change.

Every fact in every message. Your hours, prices and stock change, and a saved reply does not know that. When something changes, update the quick reply the same day, or it will keep giving the old answer.

The send button. Each broadcast goes out when you tap send, so read it once more on the day. A message written two weeks ago may not fit the day it goes out.

The conversations. The point of WhatsApp is the reply. When someone writes back, answer in your own words, the same day if you can. A saved reply is a starting point you can edit before sending, not a script for every chat. If a question keeps coming back that your replies do not cover, the objection handling job helps you write a real answer once.

App or platform

The one real choice in this job is how far into WhatsApp's tools you go.

If you...UseWhat setup asks of you
Answer customers from one phone and send a few broadcasts a monthThe free WhatsApp Business appSet up the profile, greeting, away message and quick replies; send broadcasts by hand
Have several people answering, or need replies connected to booking or ordering softwareThe WhatsApp Business Platform, through a providerPick a provider, verify the business, get message templates approved; Meta charges per message, so check current rates on Meta's site

Most small businesses never need the platform. Start with the app, and move only when one phone genuinely cannot keep up with the chats.

An editorial example

This is an invented example to show the job, not a real business.

Say you run a small bakery that takes custom cake orders. Customers already message you to ask about flavors, how far ahead to order and whether you deliver. You copy the ten most common questions from last month's chats and write the true answer to each one.

You give the AI those answers, three messages you sent customers in the past, and the month's dates: a closure for a family event, a new seasonal flavor and the cutoff for holiday orders. The AI returns a greeting, an away message with your real hours, ten saved replies under shortcuts like /order and /delivery, and three short broadcasts.

You catch one problem when you read the drafts. The delivery reply promises a delivery radius you never gave it, so you correct it to the real one before saving it. You save the replies on your phone, put the three broadcasts in your calendar with their dates, and send the first one on the day it was meant for.

If you would rather put the same month of news in a longer format, the email newsletter job uses the same inputs.

Frequently asked questions

Can AI send my WhatsApp messages for me?

Not through the chat you already pay for. ChatGPT and Claude write the words, and WhatsApp Business is where they get sent. The free WhatsApp Business app holds saved replies, a greeting message and an away message that go out on their own once you set them. Anything beyond that, such as replies written live by an AI, needs the WhatsApp Business Platform and a provider, which is a bigger setup with per-message charges.

What is the difference between the WhatsApp Business app and the platform?

The WhatsApp Business app is a free phone app for one business, with a profile, a catalog, labels, quick replies, and greeting and away messages. The WhatsApp Business Platform is for larger volume and software connections, usually set up through a provider, and Meta charges for messages sent on it. Most small businesses start with the app and only move to the platform when one phone can no longer keep up.

How often should a small business send WhatsApp broadcasts?

Less often than feels natural. WhatsApp sits next to messages from family and friends, so every broadcast competes with people the reader actually loves. Two to four a month is a pace many small businesses can defend, as long as each one carries something the reader would want: a real change in hours, a new item, a reminder before a deadline. A broadcast with nothing to say teaches people to mute you.

Do I need permission to message customers on WhatsApp?

Yes. WhatsApp's business policies expect people to have agreed to hear from you before you send them marketing messages, and privacy laws in many places say the same. Ask in plain words when you collect a number, note who said yes, and remove anyone who asks you to stop. Read WhatsApp's own business policy for the current rules, because they change and they apply to your account.

Can AI write replies to customer questions on WhatsApp?

AI is good at turning your real answers into short, friendly saved replies that you tap to send. Give it the questions customers actually ask and the true answer to each one, and it returns versions that fit a phone screen. It does not know your prices, stock or schedule unless you tell it, so read every reply before you save it and update the set whenever a fact changes.

Is WhatsApp worth it if my customers are mostly on email?

It depends on where your customers already talk to you. If they text you, ask for a WhatsApp number, or live in a country where WhatsApp is the default way to message a business, it is worth an afternoon. If nobody has ever asked, a well-kept email newsletter will likely reach more of them. Ask a few regular customers which one they would rather hear from before you build either.
