AI UGC is short-form ad creative — a creator talking to camera, a hands-on product demo, a faceless voiceover — generated by AI video models instead of filmed by a hired creator. This guide covers what to prepare before your first project, the six steps to produce one ad in UGC Copilot, which engine to render it on, and exactly what that first ad costs in credits.
What AI UGC is (and what it isn't)
User-generated content works in ads because it looks like a person sharing an opinion, not a brand making a claim. AI UGC keeps that format — handheld framing, casual delivery, one person talking about one product — but every element is generated: the on-camera creator, the setting, the voice and the product shots. The current video models (Veo 3.1, Kling 3.0, Seedance 2.0 / 2.5 and Gemini Omni Flash) render native audio, so dialogue, lip movement and room sound come out of a single render instead of a separate dubbing pass.
What it isn't: a way to impersonate a real person. The on-camera creator is either a generated persona who doesn't exist or an AI Twin built from your own reference photos (or those of someone who has given you permission). And it isn't a substitute for knowing your customer. The model renders whatever angle you give it, so the strategy still has to come from you.
What you need before your first project
- A product page or product photos. Paste a product URL and UGC Copilot pulls the product details into the brief. Clean photos on a plain background help the scene images keep packaging and labels accurate — see the product placement technique for getting the product into the creator's hands.
- One sentence on who the ad is for. "Busy parents who meal-prep on Sundays" beats "women 25–45". The script generator writes to a person, not a demographic band.
- One offer and one call to action. A discount, a free trial, a bundle. One ad, one ask.
- A destination platform. TikTok, Instagram Reels and YouTube Shorts all want vertical 9:16. The hook window is tightest on Reels and Facebook (about one second) and a little longer on TikTok and Shorts.
- A credit budget. Every step that calls a model costs credits. The cost section below prices a complete first ad.
Your first ad, step by step
1. Pick a project mode
Every project starts with a mode, and the mode decides which steps you see. Most first projects should use Product / App Ad. The others are worth knowing about:
- Clone a Video — upload a reference ad under 60 seconds (MP4, WebM or MOV). Its hook, pacing, dialogue and scene composition are analyzed, then rebuilt around your product and creator.
- Use My Own Script — paste copy you already have and it is split into scenes for you.
- Creator Video, Podcast / Talk Style and Live Broadcast Moment — creator-led formats that don't need a product.
2. Add the product
Paste the product URL or upload photos, then read the generated description carefully. This text feeds the script and every scene image, so fix a wrong claim here rather than three steps later.
3. Choose who is on camera
You have three options: a one-off AI persona generated from your product and audience brief, a reusable AI Twin, or a faceless format where the product carries the visuals and a voiceover carries the message. Faceless is the lowest-friction start because there is no face to keep consistent. Our faceless UGC guide covers the formats that hold attention without a person on camera.
4. Generate the script
The script step writes several hook options, scene-by-scene dialogue and a CTA, along with a predicted virality score. Treat the first draft as a starting point: tighten the hook until the problem, the result or the product appears in the first line, and cut any claim you can't back up. The hook formulas guide explains which hook categories suit which products.
5. Generate scene images, then render
Each scene gets a still image first — the creator, the setting and the product in frame. Review these before you render; a wrong label in the still becomes a wrong label in the video. Then choose an engine, a quality tier and a clip length. Engines that start from your scene image (Veo 3.1, Kling 3.0, and Gemini Omni Flash when you provide one) keep that exact face. Seedance builds the on-camera person from a text description, so it is a close match rather than the exact face.
6. Finish for the feed
Add text overlays — the editor suggests hook, benefit, urgency and social-proof lines for each scene and offers six style presets with safe-zone guides — then stitch the scenes together. Auto-captions are on by default when you stitch, and everything bakes into the final MP4, so there's no separate editing pass.
Which engine to render your first ad on
There is no single best engine; they trade likeness, clip length and cost against each other. The credit figures below are for one standard-quality 8-second scene, taken from the same pricing constants the app bills from.
| Engine | On-camera likeness | Clip lengths | 8s standard scene | Good first use |
|---|---|---|---|---|
| Veo 3.1 | Exact face from your scene image | 4, 6 or 8s | 40 credits (flat at any length) | Talking-head ads with a specific creator or AI Twin |
| Kling 3.0 | Exact face from your scene image | 5, 8, 10 or 15s | 40 credits | Motion-heavy scenes and longer single clips; native 4K tier |
| Seedance 2.0 / 2.5 | Close match from a text description | 5, 8, 10 or 15s (2.5: up to 30s) | 36 credits | Cheapest drafts and faceless product demos; 2.5 for long single takes |
| Gemini Omni Flash (preview) | Exact when you provide a scene image | 4, 6, 8 or 10s | 40 credits | Fast 720p drafts with native audio |
A sensible default: draft on Seedance 2.0 while you're still changing the script, then render the version you plan to put money behind on Veo 3.1 or Kling 3.0 if the creator's face matters. The AI video model comparisons go deeper on each engine.
What your first ad costs
A typical first project is a three-scene ad of about 24 seconds: one script (1 credit), three standard scene images (1 credit each) and three 8-second renders. At standard quality that comes to:
- Seedance 2.0: 112 credits
- Kling 3.0: 124 credits
- Veo 3.1: 124 credits
Add 1 credit per text overlay, and 1 credit if you run trend analysis first. HQ renders cost more — Veo 3.1 HQ is 130 credits a scene — so save HQ for a version whose hook has already proved itself. The one-time $9 Starter Pack (130 credits) covers a complete three-scene ad at standard quality on any of these engines, and monthly plans start at 500 credits on Creator ($29/month). Current plans are on the pricing page, and the free cost calculator runs the same math for your own scene count.
AI Twins vs one-off personas
A one-off persona is generated per project from your product and audience brief, which makes it ideal for testing which kind of creator your audience responds to. An AI Twin is a persistent creator you build once and reuse in every project: face consistency from five reference selfies, voice cloning from a 60-second audio sample, and locked wardrobe, aesthetic and content style. Use a Twin when the same face needs to carry a whole campaign — a founder, a brand ambassador or a recurring character — because consistency across dozens of videos is what makes a persona feel like a real creator.
Twins count against a plan limit: 1 on Creator, 5 on Pro and 20 on Business. Only build a Twin of a real person with their consent. For a first ad, a one-off persona is usually enough; build the Twin once you know which creator type converts.
Five beginner mistakes to avoid
- Testing one ad. A single video tells you almost nothing. Plan for several hook variations of the same body script and let the platform pick the winner.
- Rendering everything in HQ first. Draft at standard quality, validate the hook, then spend HQ credits on the winner.
- A slow open. On TikTok the hook should land within about 1.5 seconds, and Reels is tighter still. Lead with the problem, the result or the product — never a greeting.
- An engine that can't hold the face. If the same creator must appear in every scene, render on an engine that starts from your scene image (Veo 3.1 or Kling 3.0) rather than one that rebuilds the person from text.
- Skipping disclosure and claim checks. TikTok, Meta and YouTube all have policies on labeling realistic AI-generated content, and advertising rules still apply to what your creator says. Use each platform's AI label where it's required, and keep every claim one you can substantiate.
What to do after your first ad
Once one ad is live, the work shifts from production to testing. Write five new hooks for the body script that performed best — the free hook generator is a quick way to get options — render them as single-scene variants, and cut anything below your hook-rate baseline after a couple of days. Our TikTok AI UGC playbook lays out the full testing cadence, and the software vs freelancer comparison covers when it still makes sense to hire a human.
