AI UGC ads are short videos in the style of user-generated content, a person talking to camera about a product, where the presenter and the voice are generated by AI. They are quick to make and vary. Done honestly, the presenter is clearly an AI person who doesn't exist, and the script makes no claim a real customer couldn't.
What are AI UGC ads?
UGC (user-generated content) ads look like a customer filmed them on a phone: one person, vertical video, talking straight to the camera. Brands pay creators to make them because they feel less like ads. AI UGC video keeps the format but replaces the shoot. You write a script, pick a presenter image and a voice, and a talking-head model animates the presenter so their lips move with the generated speech.
The appeal is speed and volume. Instead of briefing a creator and waiting a week for one video, you can make five hooks for the same product in an afternoon and let the ad account tell you which one works. The risk is honesty: a realistic person praising a product looks like a testimonial, even when nobody ever used it.
How do you write a script for an AI UGC video?
The script carries the ad; the presenter only delivers it. People speak at roughly 2.5 words a second, so a 15-second video holds about 37 words and a 30-second one about 75. Short scripts read better. A structure that works for most products:
- Hook, first two seconds. A problem the viewer recognises: "My skin was always tight by lunch."
- The product, in one line. What it is and what it does, in plain words.
- One proof point you can back up. An ingredient, a feature, a guarantee you actually offer.
- What changed, said as a description, not a result. "It sinks in fast and doesn't feel greasy" instead of "it cured my eczema".
- A clear next step. "Link's below, they ship in two days."
Should AI UGC presenters look like real people?
They can look realistic, but they shouldn't be anyone real. Using a real person's face or voice without consent, or a celebrity look-alike, invites rejected ads and legal trouble. The honest option is an AI-generated person who doesn't exist, used as a presenter rather than passed off as a customer.
That is the rule we follow in Tempomat: every presenter is a photorealistic AI-generated person who doesn't exist, never a photo of a real person. The 8 presenters in our UGC library were generated from descriptions of fictional people, and the picker says so: "AI-generated presenters. None of them is a real person."
The US Federal Trade Commission's rule on fake reviews, announced in August 2024, bans reviews that "misrepresent that they are by someone who does not exist, such as AI-generated fake reviews". Its Q&A adds that the rule "has no blanket prohibition on the use of AI-generated avatars in marketing", but that actors portraying testimonialists can still be deceptive under the FTC Act. In short: an AI presenter is fine; an AI presenter pretending to be a satisfied customer is not.
Do you have to disclose AI UGC ads?
For most ads, Meta handles labelling itself. Its policy on AI in ads, updated June 1, 2026, says that when Meta's own AI tools add an AI-generated photorealistic human, the label appears next to "Sponsored", and that ads made with third-party AI tools are detected through industry-standard signals and get an "AI info" label. So expect a realistic AI presenter to be labelled; our UGC page warns about this before you generate.
Social issue, election and political ads are stricter. Advertisers must disclose photorealistic video or realistic audio made with third-party AI, explicitly including a realistic-looking person who doesn't exist, or Meta rejects the ad. If your brand runs those ads, don't use AI presenters without the disclosure. Rules change, so check Meta's pages before launch; ours were checked on October 4, 2026.
What length and aspect ratio work for AI UGC video ads?
| Choice | Recommendation | Why |
|---|---|---|
| Aspect ratio | 9:16 for Reels and Stories; 1:1 for feed | Meta's Reels ad spec is 9:16 |
| Length | 15 seconds to start; 30 for products that need explaining | Shorter scripts are easier to keep honest and tight |
| Safe zone | Keep faces and captions away from the edges | Meta's Reels spec asks for about 14% clear at the top, 35% at the bottom, 6% at the sides |
| Sound | On, with captions | Meta calls sound optional but strongly recommended for Reels; captions help when it is off |
The 9:16 ratio and the safe-zone numbers come from Meta's Instagram Reels ad specs. For testing, vary the hook first: same product, same presenter, three different opening lines. That isolates the one thing most likely to change results. Run the variants as separate ads in one paused test, give them the same budget, and judge them on cost per result and ROAS rather than on which presenter you like. Once a hook wins, keep it and test the next part of the script. Which tasks around that loop are worth automating is covered in Facebook ads automation.
How much do AI UGC ads cost in Tempomat?
In Tempomat, UGC videos cost 100 credits per started 15 seconds of video. You choose a length of 15, 30, 45, 60 seconds and an aspect of 9:16 or 1:1; the script has to fit the length before any credits move. Voices cover English, Spanish, French. The cost shows on the Generate button, and in chat the agent asks for approval first.
| Length | Credits | Words that fit |
|---|---|---|
| 15 s | 100 | about 37 |
| 30 s | 200 | about 75 |
| 45 s | 300 | about 112 |
| 60 s | 400 | about 150 |
Scripts are checked too. A UGC script that names a celebrity or makes a health, weight or income claim is refused with a plain message, and "Write with Tempomat" drafts a script from your product's real facts. The video lands in your Asset Library, ready to use in a campaign that is built paused.

- 01The script carries the ad: hook, product, one true proof, next step.
- 02Presenters are AI people who don't exist, never real faces.
- 03No testimonials pretending to be customers; no health or income claims.
- 04Expect Meta's AI label; disclose on political and social issue ads.
- 05Start at 15 seconds, 9:16, sound on with captions.
Are AI UGC ads allowed on Facebook and Instagram?
Yes, with conditions. Meta may label ads that contain AI-generated photorealistic people, and political or social issue ads must disclose realistic AI content. The ad must also follow Meta's other standards, such as its health rules.
Can I use an AI avatar as a customer testimonial?
Not honestly. The FTC's fake review rule bans reviews by people who don't exist, and actors portraying customers can be deceptive. Use the AI presenter to describe the product, not to claim personal results.
How long should an AI UGC ad be?
Start with 15 seconds in 9:16. That fits about 37 spoken words, enough for a hook, the product, one proof point and a call to action.
Do AI UGC videos need real actors' permission?
They do if you use a real person's face or voice. Tempomat avoids the question: its presenters are AI-generated people who don't exist.
Pick an AI presenter, a voice and a length, and Tempomat turns your script into a video for a paused test.
