Coaches keep running the same kind of ad: a crisp headshot, a clean background, a tidy quote. It looks professional, and it gets scrolled past in half a second because it screams “ad.” The creative that actually stops the thumb looks like something a friend posted from their kitchen.
This prompt builds ugc ads for coaches the right way. You describe your niche, your offer, and the real person in the shot, and the AI returns a detailed image prompt engineered to look candid, phone-shot, and native to the feed. By the end of this page you’ll also understand why the UGC look converts, so your next ad brief is sharper than this one.
When to use this
- You’re running Instagram or TikTok ads and your polished creative isn’t converting.
- You want “founder selfie” or “client in real life” visuals without a photoshoot.
- You’re testing cold-traffic ads and need 3-5 native-looking variations fast.
- You sell a lifestyle outcome (calm, energy, confidence) that’s easier to show than to say.
- You need an image prompt that leaves room for a text overlay.
The prompt
Copy this whole block into ChatGPT, Claude, or Gemini:
You are an expert UGC ad creative director who writes image-generation prompts for lifestyle coaches. Your job is to produce ONE detailed image prompt that generates an authentic, user-generated-content-style ad photo that looks like a real person shot it on their phone, not a studio campaign.
Before writing, ask me up to 3 clarifying questions if anything below is unclear. Otherwise, proceed.
CONTEXT
- My coaching niche: {{COACHING_NICHE}}
- What the ad promotes: {{PRODUCT_OR_OFFER}}
- Who is in the image: {{SUBJECT}}
- Where the photo is taken: {{SETTING}}
- The emotion to convey: {{EMOTION}}
- Where the ad will run: {{PLATFORM}}
TASK
Write ONE image-generation prompt (a single paragraph plus a short technical line) that I can paste into an AI image tool. The prompt must:
1. Describe the subject, their expression, posture, and clothing so they look like a real, relatable person, not a model.
2. Place them naturally in the setting with believable, lived-in details (clutter, natural light, real objects).
3. Specify a smartphone-photo look: candid framing, slight imperfections, natural skin texture, available light.
4. Match the emotion: {{EMOTION}}.
5. Match the platform aspect ratio and leave clear space for ad text overlay.
CONSTRAINTS
- Make it read like real UGC, not a polished commercial. No glossy retouching, no stock-photo perfection, no studio lighting.
- Keep the subject's body and hands natural and anatomically correct.
- Do not include logos, watermarks, readable text, or brand names in the image.
- End with a one-line technical spec: aspect ratio, lens/look, and lighting.
After the prompt, give me 2 alternative variations I could A/B test (e.g. a different setting or a different moment).
How to customize it
Replace the six {{VARIABLES}} before you send it:
| Variable | What to put | Example |
|---|---|---|
{{COACHING_NICHE}} |
Your specific niche | habit and energy coaching for burned-out working moms |
{{PRODUCT_OR_OFFER}} |
What the ad promotes | a 5-day reset email course called The Calm Restart |
{{SUBJECT}} |
Who is in the image | a woman in her late 30s in workout clothes at her kitchen counter |
{{SETTING}} |
Where the photo is taken | a sunny, slightly messy home kitchen in the morning |
{{EMOTION}} |
The feeling to convey | relieved, calm, like she finally caught her breath |
{{PLATFORM}} |
Where the ad runs | Instagram Stories and Reels (9:16 vertical) |

Here is the exact prompt, filled in for a lifestyle coach. This is the whole input, nothing hidden:

TASK
Write ONE image-generation prompt... [rest of the prompt unchanged]
And here is the complete output the model returns:
UGC ad image prompt:
Candid vertical phone photo of a real woman in her late 30s standing at her kitchen counter on a weekday morning, holding a mug of coffee with both hands close to her chest. She is wearing a worn grey tank top and black leggings, hair pulled into a slightly messy bun, no makeup or only barely-there makeup. Her eyes are softly closed or half-closed and there’s a small, genuine relieved half-smile on her face, shoulders dropped and relaxed, like she just exhaled for the first time all day. The kitchen is sunny but lived-in: a few unwashed dishes by the sink, a kid’s drawing stuck to the fridge, a bowl of fruit, a dish towel slung over the oven handle, morning light spilling in from a window to the left and catching the steam off the coffee. Natural skin texture with visible pores and a few freckles, soft window light only, slight motion in the steam, the casual slightly-off framing of a photo someone snapped of themselves on a phone. Leave the upper third of the frame relatively clean and uncluttered so ad text can be overlaid there.
Technical: 9:16 vertical, shot-on-smartphone look (wide 26mm-equivalent phone lens, mild grain), soft natural morning window light, no studio lighting, no retouching.
2 variations to A/B test:
Different moment: Same woman, but caught mid-laugh sitting on the floor against the kitchen cabinets with the coffee beside her and a phone in her lap, sun stripes across the floor, like she paused her morning to take five minutes for herself. Same UGC phone-shot look, 9:16, clean space at the top for text.
Different setting: Same woman on her front step or small balcony in a cozy oversized cardigan over the workout clothes, coffee in hand, soft golden early light, a couple of potted plants, looking out and away from the camera with a calm expression. Candid, unposed, phone-shot, 9:16, with open sky at the top for the headline.
That is ready to drop straight into your image tool. One generation, three native-looking ad variations to test.
Why this works
Three LLM principles are doing the heavy lifting here. Learn them and every prompt you write gets better:
- Role priming. The opening line (“You are an expert UGC ad creative director”) tells the model which slice of its knowledge to use. “Describe a photo for an ad” pulls the bland, stock-photo average; “act as a UGC creative director” pulls the candid, conversion-aware version. The role sets the entire tone of the output.
- Specificity in, specificity out. A UGC look lives or dies on small, real details: the messy bun, the kid’s drawing on the fridge, the visible pores. The prompt forces those out of the model by asking for “believable, lived-in details” and “natural skin texture.” Vague input (“a woman in a kitchen”) produces glossy stock imagery; concrete input produces something that looks human. The realism of the image is capped by the specificity of your
{{SUBJECT}}and{{SETTING}}. - Constraints are quality control. The “no glossy retouching, no studio lighting, no logos or text” rules each kill a specific failure mode that makes AI ad images look fake. Telling the model what NOT to do is as powerful as telling it what to do. And the “ask me up to 3 clarifying questions first” line lets it fill gaps by asking instead of guessing, which is the biggest fix for generic, off-brief creative.
Do this now
- Copy the prompt above into ChatGPT, Claude, or Gemini.
- Replace the six variables with your real niche, offer, subject, setting, emotion, and platform.
- Send it. If it asks clarifying questions, answer them honestly, then paste the returned image prompt into your image tool.
- Generate the main version plus both variations, then run all three as ad creative and let the data pick the winner.
Pro tips
- Cast a real-looking person, not a model. “Tired but hopeful, no makeup” beats “beautiful woman” every time for UGC. Relatability is the whole point.
- Name the imperfections. Explicitly ask for grain, slightly-off framing, and clutter. Perfection is what tips viewers off that it’s an ad.
- Protect the text zone. Keep the “leave clear space for text overlay” instruction so your headline doesn’t land on a face.
- Generate in batches and screen for hands. AI still fumbles hands and fingers. Make 4-6 and discard any with anatomy errors before you spend ad budget.
