How to make an AI ad? A step-by-step guide
In short
An AI ad is now a matter of minutes, not days or an agency budget. We show you how to make one step by step — from idea to finished creative.
Not long ago, preparing an ad required a designer, a copywriter and often an agency. Today, thanks to AI, you can create a finished creative — graphics, video, copy and voiceover — yourself in minutes. Here is how to make an AI ad step by step.
1. Start with a clear message
Before you generate anything, write in one sentence: what you advertise, to whom, and what benefit you promise. The more specific, the better the result — AI works best with a precise brief.
2. Generate the ad graphic or video
Describe the scene, product and style (e.g. a luxury perfume bottle on marble, dramatic studio light). Pick a model that fits the need — fast and cheap for tests, flagship for the final creative. For video you describe the scene or upload a product photo and bring it to life with motion.
- Vertical format (9:16) for Reels, TikTok and Stories
- Horizontal format (16:9) for YouTube and Google
- Square (1:1) for the Facebook and Instagram feed
3. Add copy and a voiceover
A good ad is not just an image. Generate a headline and a short description (CTA), and add a voiceover to the video — a natural voice reading your message. All from one prompt.
4. Test several variants
AI's biggest edge is speed. Generate 3–4 variants of the same ad, run them in a campaign and see which performs best. A cheap A/B test that used to be out of reach for small businesses.
Summary
An AI ad is now a real alternative to expensive production. With one prompt you create graphics, video, copy and voiceover — and test what works. In FATTLY you have all these tools in one place.
