The words that sell the picture

A good photo still needs a headline, a line of body text and a button. Ad Copy writes 5 complete ads from what you tell it about the product — each one a different way of selling it, each counted against the length the platform cuts at. This guide plays the real screen and shows a real sheet, word for word.

What Ad Copy is

The picture stops the scroll; the words decide whether anyone taps. Ad Copy writes the four parts of an ad — the headline, the main text, the description and the button — as complete sets, so what you get can be pasted straight into the ad manager.

It writes only from what it is told. Describe the product in a sentence or two, pick it from your catalogue, or add your brand voice, and every claim in the result can be traced back to something you said. Anything past the platform's length limit is brought back to a whole sentence before you see it.

Good for

  • Writing the words for an ad you already have a picture for
  • Testing five ways of selling the same product at once
  • Copy in Thai or English from the same brief
  • Catching wording that gets ads refused before you post

How it works, in four steps

  1. 1

    Describe what you sell

    Pick a product from your catalogue, or write a sentence or two about it. The writer uses nothing else, so what you put here is what it can say.

  2. 2

    Choose the angles

    6 ways of selling the same thing. Leave them all on and each ad takes a different one, or say what the ad is for and the matching ones are picked.

  3. 3

    Write the sheet

    5 complete ads in one 2-credit run. The price is on the button before you press it.

  4. 4

    Keep, copy or rewrite

    Copy any box straight into your ad manager, keep the ones you use, and rewrite a single box — a 2-credit change — without touching the rest.

Tell it what you sell

The brief is the only thing the writer knows about the product. There is no research step and no guessing — so a sentence about who it is for and why it is different is worth more than any setting below it.

Choose how to sell it

An angle is the reason a stranger should care: the problem it removes, what changes once they own it, the doubt that stops them buying. Ad Copy has 6, and each one says in its ? what it will give you.

Problem first

Names the annoyance the product removes before it names the product. Works when people do not know they need it.

Social proof

Leads with other buyers. Strongest for something people hesitate to be first on.

Reason to act now

Gives a real deadline or a real limit. Empty urgency reads as pressure and gets scrolled past.

What changes for you

Describes the after, not the features. Good default when nothing else obviously fits.

Answers the doubt

Takes the reason people do not buy and answers it out loud. Useful when the price is the sticking point.

Makes them look

An opening that is hard to scroll past. Risky — it must pay off in the next line or it reads as clickbait.

Write the whole sheet

One press writes every ad at once, each in a different angle. The count is yours — up to 10 — and the price for that count is on the button.

Read it the way the platform will

Each box is counted against the length the platform shows before it cuts the text off. A line that would have run over is ended at its last whole sentence, so nobody reads half a thought followed by an ellipsis.

Rewrite one box, not the ad

When one line is wrong and the rest is right, rewrite just that line. The writer sees the whole card so the new line still belongs to it, and each one is a 2-credit charge — never free, because the whole brief is sent again.

Every ad from one real Thai run, unedited. Button wording stays in English because the ad platforms show their own translated button.

What it checks before you post

Some wording gets ads refused on sight. Ad Copy reads every card against 10 phrases, in English and Thai, and warns on the card that has one — with the reason and a safer way to say it.

Might get this ad rejected

  • “guaranteed”Promising a result is one of the most common rejection reasons. Say what it does, not what it will definitely achieve.
  • “cure”Health claims need evidence most sellers cannot supply, and get ads refused on sight.
  • “are you overweight”Naming a personal attribute back at the reader breaks the personal-characteristics rule.
  • “best in the world”An absolute superlative you cannot evidence. Narrow it to something true and specific.
  • “free money”Reads as a scam signal to automated review whatever the context.
  • “รับประกันผล”Promising a result is one of the most common rejection reasons.
  • “รักษาหาย”A medical claim needs evidence most sellers cannot supply.
  • “ดีที่สุดในโลก”An absolute superlative that cannot be evidenced.
  • “ขาวใสภายใน”A timed cosmetic result promise — a frequent rejection in this market.
  • “ไม่พอใจยินดีคืนเงิน”Only claim a refund policy you actually operate — it is checked.

A warning never deletes anything. Only you know whether a claim is true for what you sell, so the studio points at the phrase and leaves the decision with you. The list is kept in Admin, because what is risky depends on the product and the market.

Once you have kept a few, each card also shows how often you kept that angle before — read from your own library, not from anybody else's. It is the part a general writing tool cannot copy: it gets more useful the more you use it.

Getting more out of it

Six habits that turn a sheet of options into ads that run.

  1. 1Give it one fact nobody else has

    A burn time, a material, who it is for. The writer can only be specific about what it is told, and specific is what gets read.

  2. 2Say what people ask before buying

    Put the usual question in the notes. The “answers the doubt” angle will answer it out loud.

  3. 3Give real proof, or skip the angle

    The writer never invents reviews or sales. If you have a rating or a number, put it in the brief; if not, the proof angle talks about what owners notice instead.

  4. 4Run the angles against each other

    Post two or three cards from one sheet as separate ads. The one that wins tells you how your customers want to be sold to.

  5. 5Rewrite the line, not the sheet

    If a card is nearly right, rewrite the one box — a 2-credit change — rather than running the whole sheet again.

  6. 6Keep what you post

    Keeping is free and teaches the studio which angles you choose, so the next sheet tells you which ones have worked for you.

What it costs

A sheet is priced as one run whatever the angles; a rewrite is priced on its own, because it sends the whole brief again for one line back.

Questions people ask

Does it make things up?+

It is told not to, in every run: no invented reviews, numbers, awards or stock levels, and every claim must come from the brief. If you want proof in the ad, give it the proof.

Which languages does it write?+

The language your screen is in — Thai or English — unless the operator has fixed one. The brief can be in either.

What happens if a line is too long?+

It is ended at its last whole sentence within the limit, so the platform never cuts it mid-word. If that would leave too little, the line is shown in full with a red count instead.

Why does rewriting one box cost credits?+

Because the whole brief, the brand and the card are sent again for the sake of one line. It is a 2-credit charge, never below what it costs to run, and capped at 40 a day.

Can it use my brand voice?+

Yes. Pick a brand from Brand Kit and its tone of voice, audience and values go into the brief with the product.

Will the checks stop my ad?+

No. They warn and explain; they never delete or block. Only you know whether a phrase is true for what you sell.

How many ads can one run write?+

Up to 10. The default is 5, and the button shows the price for whatever number you choose before you press it.
