How to Make AI UGC Ads: Script, Avatar, Voice and Rules

An AI UGC ad is a short, phone-style video in which an AI-generated presenter, or an AI clone of you, talks about a product the way a real person would. You make one in five steps: write a 15 to 30 second script, generate the presenter, add a voice, edit it like a native post, and label it where the platform asks. The rule that keeps you safe is simple: an AI presenter can recommend your product, but it cannot pretend to be a customer who used it.

What counts as an AI UGC ad

UGC stands for user-generated content: videos that look like an ordinary person filmed them on a phone. Brands pay creators for this style because it feels like a recommendation, not an advert.

AI UGC keeps the look and replaces the filming with generation. That lets you test many hooks in the time it takes to brief one creator. There are three practical ways to do it.

Every AI UGC ad, whichever route you pick, goes through the same five steps.

Step 1: Write a script that sounds like a person

Most AI UGC ads fail at the script, not the video. A strong script has five beats:

1. Hook. The first two seconds: a line or an action that makes the right person stop scrolling.
2. Problem. The annoying situation your buyer recognizes.
3. Product moment. The product doing its job on screen.
4. Reason to believe. One fact you can prove, such as a material, a guarantee or a price.
5. Call to action. What to do next, in plain words.

Keep it to one product and one benefit, and write for the ear: short sentences, contractions, the odd half-sentence. In the US, the FTC's Endorsement Guides say an advertiser needs proper evidence for claims made through endorsements, exactly as if the brand said them, and that covers anything your AI presenter says.

Here is the prompt I start from with Claude. Replace the bracketed parts.

You write UGC-style ad scripts for [PRODUCT], sold to [WHO BUYS IT].
Use only these facts and add no others: [3 TO 5 TRUE FACTS, PRICE, OFFER].

1. Write 10 hooks, each under 12 words. Start mid-action or mid-thought. Do not name the brand in the first line.
2. Write 3 scripts of 60 to 75 spoken words with these beats: hook, problem, product moment, one provable reason to believe, call to action.
3. Do not write customer results, before-and-after claims, or lines like "I've used this for weeks". No health or money promises.
4. After the scripts, list every claim they make so I can check each one against my facts.

When a draft slips, push back in the same chat. One short exchange usually fixes it:

If you write ad scripts every week, a reusable brief inside Claude Code saves a lot of repetition. The Claude Code for marketers guide shows how to set one up.

Step 2: Generate the presenter

Pick one route per ad. You can mix routes across a campaign, and you should test them against each other.

Option A: a template tool

Higgsfield's Marketing Studio has a UGC Videos category in Faceless, Talking Head and Silent formats. You upload a product image, or a reference ad you are allowed to use, and it rebuilds that structure around your product.

Option B: your own AI clone

A clone works well for founders, because the audience already knows the face. In Higgsfield you train a Soul ID on 20 or more photos of yourself, then make the clone talk in Lipsync Studio. The Higgsfield tutorial walks through the training step by step.

Only train on your own photos, or on photos of someone who has given you permission. Higgsfield's instructions and its terms both require that permission, and getting it in writing protects you later.

Step 3: Add the voice

You can get speech in two ways, and each has a clear use.

For separate tracks, ElevenLabs is the usual choice. Its Instant Voice Cloning works from a short, clean sample, while Professional Voice Cloning needs a long recording and a verification step, and only clones your own voice.

Two small fixes make any AI voice sound more human. Spell your brand name the way it sounds if the model trips on it, and add a comma wherever a real person would take a breath.

Step 4: Edit it like a native post

Match what people already scroll past every day: vertical 9:16, fast, and readable with the sound off.

• Open on movement. Start the action in the first second. A still first frame reads as an advert.
• Burn in captions. Large, high-contrast words carry the message for people watching on mute.
• Show the real product. AI models often redraw labels, small text and logos, so use real footage or a real product photo for close-ups. The AI product photography guide covers how to keep the product accurate.
• Cut every pause. Then cut a little more.
• Hunt for AI tells. Check hands, teeth, packaging text, wobbling logos, lip sync on long lines and background people who change shape.
• Make hook variants. Change only the opening across 3 to 5 versions, so you learn which hook works.

Step 5: Label it and keep it honest

What the FTC cares about

The FTC's rule against fake reviews and testimonials took effect on October 21, 2024, and courts can impose civil penalties for knowing violations. FTC staff say the rule has no blanket ban on AI avatars: an avatar testimonial breaks the rule when the testimonial underneath is fake or false, although avatars can still be deceptive under the wider FTC Act (FTC Q&A on the rule).

The Endorsement Guides add three points that matter for AI UGC:

• Actual consumers. An ad that presents people as actual consumers should use actual consumers in the audio and video, or clearly disclose that they are not.
• Real use. If the ad says the endorser uses the product, that person must really have used it.
• Clear and conspicuous. A disclosure has to be hard to miss. If a claim is both shown and spoken, disclose it on screen and out loud.

In plain terms, your AI presenter can explain, demonstrate and recommend in the brand's voice. It should never say "I've used this for a month and it changed everything", because nobody did.

What the platforms require

Pre-launch checklist

Run through this list before any AI UGC ad goes live. Tick each item on the final export, not on a draft.

What to do next

Pick one product and run the script prompt until you have 10 hooks you like. Make three ads that differ only in the hook, label them, and run them next to one real customer video on the same budget, so you learn what your audience trusts. If you want to see the full workflow done on screen, from moodboard to voice to final edit, it is the core of the Creators course.
