How to make a UGC ad with AI

make.ad’s UGC page (Talking person, under Create in the studio) is the brief form set up for one person in one seat. make.ad draws that person sitting where you describe, looking into their phone’s front camera, and that one picture is the whole video: no cutaways and no b-roll, just them talking to the viewer.

They are photoreal unless you ask for a look. The script is theirs, said straight to camera, and the finished ad is cut like a real post: the quiet before and after each line is trimmed, and every other line is slightly punched in, so each join reads as a jump cut rather than a glitch.

There are two ways to make the person talk, and the choice decides how the voice behaves. Spoken is the default: every line is its own clip of the person saying it, rendered with its own sound on Gemini Omni 1.1 Flash. A take records a voice reading the whole script first, then makes the person say it with one lip-sync render.

Describe the person as a casting note: age, look, where they are sitting, and what they are wearing if it matters. Then say what they talk about: how they found the product, the problem it fixed, one specific detail they noticed, and why the viewer should try it.

The specific detail does the most work. “It’s amazing” sounds like an ad; “it dissolves in about a minute and doesn’t taste salty” sounds like a person. Only write details that are true of your product.

Here is a brief to copy. The brand in it, Fizzline, is made up.

You can also paste a finished script instead of a brief: it is cut into lines, one sentence each, and every word you wrote is kept.

1. Save your brand once: its name, one line about it, the audience, its website and the claims it must never make. The never-claim list is read before an own script is made into anything.
2. Open Create, choose Talking person, and write the brief or paste your script.
3. Pick how it is filmed (spoken or a take) and, for a take, the voice. Pick the language the person speaks if it is not English.
4. Check the quote. Every ad is priced in credits before it starts, and a render that fails gives its credits back.
5. Approve the person. This picture is the whole video, so check the face, the setting and anything they hold.
6. Approve the script. Read it out loud: if a line sounds like a slogan, rewrite it as something a person would say.
7. Watch the finished ad with the sound on. Refilm any spoken line that came out wrong, add captions from the finished video’s page, then download the MP4 or copy a share link.

• One person, one place, one problem. A UGC ad that tries to say four things says none of them.
• Keep lines short. In a spoken ad each line has to fit inside one clip, so the script is written to a word count, and a line that runs long is refused before anything is filmed.
• Open on the problem or a confession, never on the brand name. The first two seconds decide whether anyone hears the rest.
• End on one ask: try it, get a tube, use the code. Two asks halve both.
• Burn captions in. Plenty of people scroll with the sound off, and captions cost nothing on a finished make.ad ad.
• Make three versions with different openings before you judge the angle. A batch makes up to 20 ads with the same settings, one angle each. On the site a batch runs on auto by default, without stopping for reviews; set it to stop at each review if you want to approve every ad.

The person in an AI UGC ad is not a customer, and the ad should not pretend they are. Don’t invent testimonials, results or reviews, don’t claim what your product cannot back up, and follow each ad platform’s rules on AI-generated people and disclosure. The never-claim list on your brand is there to catch the claims you already know are off limits.
