Your Reels ad and the site it points to, made in the same chat

Vertical is where the audience is

The numbers are not subtle. On Alphabet's fourth-quarter 2025 earnings call on February 4, 2026, Google said YouTube Shorts now averages about 200 billion daily views, and that in a number of countries, the United States included, Shorts earns more per watch hour than traditional in-stream video (as reported by TheWrap, checked September 2026). This post uses one platform's figure rather than guessing at the others. One is enough to make the point: the short vertical clip is the format a small business is seen in first.

What a vertical ad needs is also not subtle. A hook in the first second. One promise. One piece of proof. A call to action that names the next step. And a page at the end of the link that keeps the promise the clip made, in the same words, with the price the clip implied and the button the clip told them to press.

The three-tool problem

Ask a creator who runs a small shop, a studio or a service how an ad gets made and you will hear about three tools that have never met.

The result is drift. The ad says “book a free first class” and the page says “trial session, $15”. The ad shows a dish the menu dropped in spring. The call to action says “order now” and the page has a contact form. None of this is a failure of talent. It is what happens when the words live in three places.

One project, one set of facts

On JustCopy the site comes first, and it comes from one sentence. Say what the business is and what the page should do, and the page is on screen in seconds: the services, the prices, the hours, the form or the shop. Change anything by typing the change. That page is now the source of truth, because it is the thing the ad will point to.

Then, in the same chat, ask for the ad. The agent knows the app can make moving video from words, and it knows an ad from a brief is two steps, never one. The first step is the script. It reads the page and writes the scenes: what is spoken and what is shown, with a hook, a promise, proof and a call to action. It uses only the facts on the page and in your message. It does not invent a price, a rating, a number of customers or a guarantee. The script is shown to you as text you can edit before anything is made.

The second step makes the clips. Each scene starts from a picture drawn in your chosen style by Nano Banana 2, which Google publishes as Gemini 3.1 Flash Image. That picture becomes the first frame, so a scene keeps the look the picture was drawn with. Motion comes from Seedance 2.5 through OpenRouter, one clip of 4 to 15 seconds per scene. Narration, if you want a voice, is read from the script. The scenes are assembled with the voice and music into one file with a lasting link, ready to upload.

Because the script was read from the page, the ad cannot promise what the page does not say. Change the price on the page next month and ask for a new ad; the new script carries the new price. That is the whole argument for doing this in one chat rather than three tools.

What a 15-second ad costs

Everything metered on JustCopy has one price, the same on every plan, deducted from a prepaid balance on your account. Video is 50 cents a second. A picture is 15 cents. A reply, which is what the script step is, is 2 cents. Narration is 10 cents a minute. A three-scene, 15-second ad with a voice comes to this:

Two things keep that number honest. Only the seconds actually made are charged: a scene whose clip fails stays a still and the ad still goes out, and a film that fails entirely is never charged. And a scene runs as long as its narration, so a line that takes seven seconds to say makes a seven-second scene. The estimate before you approve reads the words, not just the number you asked for. Watch the total in the chat before saying yes.

Set your expectations on time

The script is fast: under three seconds in our first production run. The clips are not. A 5-second clip came back in about three minutes, and a two-scene ad, with both scenes made in parallel, was ready a little under six minutes after it started. Plan for minutes per clip, made side by side, and do not sit and watch the pane. The app tells you when the ad is ready and the file keeps its link.

One more limit. The video model refuses a photo-real person as a first frame, and the content rules refuse a real person's likeness in any picture. When that happens the clip is made from the words alone, and the reply tells you so. Ads of the product, the room, the plate, the before and after, or a stylized character all work. An ad that needs your own face on camera is still a job for your phone.

What the free plan can try

Building and publishing the site is free and needs no card. In the studio, a free account can also try 5 seconds of video a day at our cost, along with three pictures, twenty replies and two minutes of narration. That is one moving scene of your own product, every day, to see whether the style suits you before you spend anything.

Making a whole ad needs a balance, and a balance needs a paid plan. Hobby is $9.99 a month: your site on your own domain without the badge, five AI builds a day, and pictures, voices and videos pay as you go. The first paid subscription comes with a $2 credit on the balance, about four seconds of video, so the first thing you make is on us. Every plan has a daily ceiling for what an app may spend, set in the project's settings, so a busy week cannot surprise you.

Three messages

1. 1

   Build the site

   One sentence about the business. The page is on screen in seconds, with the offer, the prices and a form or a shop.

2. 2

   Ask for the ad

   In the same chat: "Make a 15-second vertical ad for this." The script step reads the page and shows you the scenes to edit.

3. 3

   Approve and wait

   Say yes. Each scene gets a first frame, then motion. A few minutes later the ad is a file with a lasting link, ready to upload to Reels.

That is the whole workflow. No exporting a script, no re-typing the offer into a prompt, no checking whether the page still says what the ad says. The page is the brief. When it changes, ask for a new ad and the script changes with it.
