Concepts, not synonyms
Three concepts give people three different reasons to stop scrolling. You test angles on Facebook, Instagram or LinkedIn instead of testing word order.
The AI ad copy generator for brands. Three ideas, not three rewordings.
DFIRST Ad copy is an AI ad copy generator that turns a short description of what you are promoting into three distinct ad concepts. Each concept has a headline, a two-sentence body and a call to action, written in the tone you choose and only from the facts you give it.
- Three concepts in every result
- Headline, body and call to action
- No invented claims or discounts
What you get. Three concepts from one brief.
Examples in the shape the tool returns, with the brief under each one.
Example output

Three cans, three moods: Tangerine, Grapefruit and Lime. Sparkling citrus water from Barcelona, with zero sugar.

How to write ad copy with DFIRST.
Three steps. The first one starts on this page.

Describe the offer
Write what you are promoting, who it is for and any line or call to action you want kept, then pick Natural, Confident or Playful. The facts in your brief are the only facts the copy will use.
- 02
DFIRST writes three concepts
Each concept takes a different angle on the same product, with a short headline, a two-sentence body and a call to action. Run it again for a fresh set.
- 03
Pick one and keep going
The copy is saved to your session and your Data Room. Download it, or take the strongest headline into a banner or a set of ad creatives.
Made for brands. Not a blank prompt box.
Only what is true
The tool is told to use only the product facts in your brief. It does not add discounts, testimonials or performance claims you did not give it, so there is less to check before an ad goes out.
Your voice in a session
In a session, the agent writes with your Brand DNA, so the voice and the audience come along. The copy can then go straight into a banner.
Who uses it.
Performance marketers
New angles for paid social every week, with headlines short enough for the feed.
Agencies
Three routes to show a client in the first meeting, each with its own headline and call to action.
Founders and small teams
Ads for a launch or a seasonal push, written from the product facts they already have.

Questions people ask.
About Ad copy and how it fits the rest of DFIRST.
How do I write ads with an AI ad copy generator?
Describe the product or offer in the box above: what it is, who it is for and the call to action you want. Pick a tone and continue in DFIRST. You get three ad concepts, each with a headline, a body and a call to action, saved where you can find them again.
Can it write Facebook ad copy?
Yes. Each concept is short enough for Facebook and Instagram feeds: a headline, two sentences of body copy and a call to action. Paste the one you like into your ad account, or press Generate again for a new set. DFIRST does not publish ads for you.
Is it a headline generator too?
Every concept starts with its own short headline, so one run gives you three headlines, each from a different angle. Run it again for more. To see a headline on the image itself, in several sizes, take it into the banner tool.
Will it make up claims or discounts?
No. The tool is told to use only the product facts in your brief and to leave out anything it cannot support, including discounts, testimonials and performance claims. If you want a price or an offer in the ad, write it into the brief.
Does it write in my brand's voice?
The tool writes in the tone you pick and the language of your brief. For your full brand voice, work in a session: with Brand DNA set up, the agent writes ad copy the way your brand already speaks.
Which languages does it write in?
It answers in the language of your brief, so a brief in Polish gets Polish ads and a brief in German gets German ones. To move an ad you already have into another market, use Localize ad copy.
