AI UGC video generator

Build the script first, then generate it. The dialogue and the picture come out of one sampling pass, so nothing has to be lip-synced afterwards.

Ad angle

About 7.2s of speech, 0.7s over. Cut roughly 2 words.

Your generation prompt

A woman in her 20s-30s, in a bright cafe, presenting the product. They speak on camera, in English, saying: "I've been using this for a couple weeks now, and honestly, it's held up better than I expected." Shot in 9:16 aspect ratio as a 10-second UGC-style ad, handheld and casual, natural lighting.

Copy it and run it anywhere. It is a plain prompt, not a lock-in format. The reason to run it here is that the dialogue comes out of the same sampling pass as the picture, so there is no voiceover to sync afterwards.

What people get wrong about AI UGC ads

These are questions advertisers were actually asking each other, not a feature list. Where the honest answer is unflattering to the category, it says so.

Why did one 5-minute clip cost more credits than ten short ads?
Lip-sync compute scales with duration, not with whether the result was any good. A single long take re-solves mouth shapes across every frame, and if the take is unusable you paid for all of it. Generate in 5 to 8 second beats and stitch them. Sync comes out cleaner, and a bad beat costs you one beat instead of the whole ad.
Can I see what a generation costs before I run it?
Yes. The price is quoted from duration, resolution and model before you submit, and the credits reserved are that same number rather than an estimate settled later. A generation that fails releases its reservation, so you are not charged for output you never received.
My AI presenter looks slightly different in every batch. Does that matter?
It matters more than any single batch looks. Brand recall is built on one face staying the same across months of impressions. A presenter that shifts a few percent per batch reads as a different person by the tenth flight, and the recall you paid to build resets. Lock the character reference and the voice and reuse them across variants rather than re-rolling the actor per campaign. This is a discipline the tool supports, not a problem any generator has fully solved: if absolute consistency over years is the requirement, a trained digital twin is a different and more expensive product category.
What should the script actually sound like?
Like one person telling one friend about something they bought, not like a commercial. Long polished copy is the most common reason a technically perfect generation still reads as an ad. Write the first line as the thing you would say out loud, keep it under about fifteen words, and put the product in the second sentence rather than the first.
Do AI UGC ads actually convert, or do people scroll past them?
Both happen, and which one you get is mostly decided before you open a generator. Reported results in advertiser communities range from ROAS of 3 to 4 down to click-through below the same brand’s real-creator footage. The ads that underperform tend to be the ones trying to pass as a real person recommending a product. The ads that work use a synthetic actor for the thing it is good at, which is testing ten angles in a day, and keep the product footage real.
Do I have to disclose that the actor is AI?
Increasingly yes, and in more places than the law strictly requires. New York requires synthetic-performer labelling on advertising, the EU AI Act transparency article applies from August 2026, and Meta labels generated creative automatically whether or not you declare it. Plan the ad so disclosure costs you nothing. The campaigns that lost the most to labelling were the ones whose entire premise was that the viewer believed a real person was speaking.
How many versions of an ad do I actually need?
The bottleneck is angles, not polish on any one clip. Advertisers working this way generate ten to fifteen concepts from a single product and cut fast, which is a schedule real creator shoots cannot match. That is the honest position of AI UGC: a middle layer between static ads and expensive creator content, used to fill the testing gap rather than to replace the creator whose footage wins.

Five angles, and the prompt each one produces

Every prompt below is assembled by the same code the builder above runs, for one example product. The speech estimate is how much of the clip the spoken line uses, which is the number that decides whether a line has to be cut.

Generated clips are not shown here yet. We would rather leave this space empty than fill it with footage that was not produced by this product for a real campaign, which is the same standard the section above asks advertisers to hold themselves to.
