Quick answer
To write a UGC ad script for an AI spokesperson video, decide on one product, one audience and one message first. Then write a short spoken script in five parts: a hook in the opening seconds, the problem your viewer recognises, the product moment, one piece of proof you can back up, and a clear call to action. Keep it to roughly 35 to 40 spoken words for 15 seconds or 70 to 80 for 30 seconds, write it the way people talk, and read it aloud before you generate. Finally, run honesty checks: an AI spokesperson is not a real customer, so never present it as a genuine testimonial.
Key takeaways
- Start with one product, one audience, one message
- Use a five-part script: hook, problem, product moment, proof, call to action
- Rule of thumb: about 2.5 spoken words per second
- Match the spokesperson and scene to where your audience actually is
- Only claim what you can evidence; no invented results
- An AI spokesperson must not pose as a real customer
- Generate a small batch, compare, retry and keep the best

UGC-style ads work because they feel like a real person talking to you, not a brand shouting at you. With an AI spokesperson, the look is easy. The words are the hard part.
This guide shows you how to write a UGC ad script for an AI spokesperson video, using the UGC studio we cover in Scale.gg Creator Studio: 7 AI Creator Studios for Every Content Format. The structure works in any AI video tool, but the steps follow the four inputs that studio asks for.
What goes into an AI UGC ad?
In the Scale.gg Creator Studio UGC studio, as shown in our video, an ad is built from four inputs, and then the video is generated:
| Input | What you decide | Common mistake |
|---|---|---|
| Spokesperson | Who delivers the message | Picking someone who does not look like your audience’s world |
| Scene | Where they are | A setting that has nothing to do with how the product is used |
| Product | What is being shown | Too many products or features in one ad |
| Spoken script | Exactly what they say | Writing it like a brochure instead of a conversation |
The script carries the message, so most of this guide focuses on it.
Step 1: Who is the ad for, and what is the one message?
Before you write a word, finish these three sentences:
- This ad is for … (one specific type of person)
- They are struggling with … (one problem in their words)
- After watching, I want them to … (one action)
If you cannot finish them in one line each, the ad is trying to do too much. Split it into two ads instead.
Step 2: How do you choose the spokesperson and scene?
Choose a spokesperson and scene that make sense for the viewer. A few practical pointers:
- Match the setting to real use: a kitchen for a recipe planner, a desk for a work tool
- Keep it simple: a plain, believable scene keeps attention on the message
- Stay consistent if you plan a series of ads, so viewers recognise them
💡 Tip: Write a one-line scene note, for example “Bright home kitchen in the morning, product on the worktop”. A clear, specific scene usually gives more believable results than a vague one.
Step 3: How should the product appear?
Decide what the viewer should see when the product appears. Pick one thing: the product being used, the result it produces, or the moment it solves the problem.
Show one product and one main benefit. Extra features belong on your landing page, not in a short social ad.
Step 4: How do you structure the UGC ad script?
Use this five-part structure. It keeps the script short, clear and honest:
| Part | Job | Example line (fictional product) |
|---|---|---|
| Hook | Stop the scroll in the opening seconds | “I used to waste every Sunday deciding what to cook.” |
| Problem | Name the pain in the viewer’s words | “By Wednesday the plan had fallen apart and we were ordering takeaway.” |
| Product moment | Show how the product helps | “Now I fill in this planner once and the shopping list is done.” |
| Proof | One claim you can back up | “It has a page for every week of the year.” |
| Call to action | Tell them exactly what to do next | “Tap the link to see inside.” |
Write it the way people speak: short sentences, everyday words, and “I” and “you” rather than “our customers”. Then read it aloud. If you stumble, the spokesperson will sound awkward too.

Step 5: How long should the script be?
A useful rule of thumb is that natural speech runs at roughly 2.5 words per second. Leave a little breathing room for the product shot and the call to action:
| Ad length | Spoken words (approx.) | What fits |
|---|---|---|
| 15 seconds | 35 to 40 | Hook, product moment, call to action |
| 30 seconds | 70 to 80 | All five parts, briefly |
| 60 seconds | 140 to 150 | All five parts, with a short demo |
If you want a longer ad with several scenes and the same character throughout, the storyboard studio (15, 30 or 60 seconds) may suit the job better than a single UGC clip.
Step 6: What honesty checks does an AI spokesperson ad need?
This step matters as much as the writing. Before you generate, check your script against this list:
- No fake testimonials: the AI spokesperson must not claim to be a real customer or describe experiences nobody actually had
- Evidence for every claim: if you say it, you can prove it; no invented results or income promises
- Platform rules: check your ad platform’s current policy on AI-generated or synthetic media and any labelling it requires
- Advertising rules: in the UK, the CAP Code says ads must not mislead and testimonials must be genuine
- Rights: only use product images, music and brand assets you are allowed to use
⚠️ Warning: A line like “This changed my life, I made £5,000 in a week” spoken by an AI presenter is both a fake testimonial and an unsupported claim. Rewrite it as a plain description of what the product does.
Step 7: How do you generate, compare and improve the ad?
As shown in our video, Creator Studio lets you compare the candidates, retry what needs work and choose what gets saved. Use that to improve one thing at a time:
- Generate a small batch and watch each one with the sound on
- Check the basics: is every word clear, does the product appear, is the call to action audible?
- Change one input per retry, such as the hook line or the scene, so you know what made the difference
- Keep the best in your gallery and note which script version it used
Video workflows show an estimated provider cost before generation, so glance at it before each retry. Our guide How to Estimate the Real Cost of an AI Ad Tool covers budgeting in more detail.

Frequently asked questions
What is a UGC ad script?
It is the spoken script for a user-generated-content style ad: a short, conversational message delivered by one person, usually with a hook, a problem, the product, proof and a call to action.
How many words should a 30-second UGC ad have?
Roughly 70 to 80 spoken words, based on natural speech of about 2.5 words per second.
Can an AI spokesperson give a testimonial?
No. A generated presenter is not a real customer, so it should never claim personal results or pose as a genuine reviewer.
Do I need to label AI-generated ads?
It depends on the ad platform and where you advertise. Check the platform’s current policy on AI-generated or synthetic media before you publish.
What does the Scale.gg Creator Studio UGC studio need?
A spokesperson, a scene, a product and a spoken script. It then generates the video.
Where can I learn about the other studios?

The bottom line
A good UGC ad script for an AI spokesperson video is short, specific and honest. Pick one message, follow hook, problem, product moment, proof and call to action, keep it to the right word count, and never let an AI presenter pose as a real customer. Write one script today, read it aloud, then generate a small batch and compare.
