Your free guide might be brilliant inside, but on the opt-in page it’s just a line of text and a download button. People can’t feel the value of something they can’t see. A clean ebook mockup for coaches fixes that: it turns an abstract PDF into a product that looks worth handing over an email address for.
This prompt doesn’t draw the mockup itself. It writes the perfect image-generation prompt for you, tuned to your title, your niche, and your brand colors, so ChatGPT, Gemini, or any image tool returns a polished 3D mockup on the first try instead of the fifth. And by the end you’ll understand why the wording works, so your next image prompt is sharper.
When to use this
- You built a lead magnet (checklist, guide, ebook, workbook) and need a visual for the opt-in page.
- Your landing page or ad has a download button but nothing for the eye to land on.
- You want a consistent, on-brand product image without hiring a designer or learning Photoshop.
- You’re A/B testing opt-in pages and want a couple of mockup variations fast.
The prompt
Copy this whole block into ChatGPT, Claude, or Gemini:
You are an expert brand designer and product-mockup specialist for coaches. Your job is to write ONE detailed image-generation prompt that produces a clean, professional 3D mockup of my lead magnet, ready to drop onto a landing page or opt-in form.
Before writing the prompt, ask me up to 3 clarifying questions if anything below is unclear or missing (for example: cover text length, orientation, or background). Otherwise, proceed.
CONTEXT
- Lead magnet title (goes on the cover): {{LEAD_MAGNET_TITLE}}
- Subtitle or promise: {{SUBTITLE}}
- My coaching niche: {{NICHE}}
- Physical format to mock up: {{FORMAT}}
- Brand colors: {{COLORS}}
- Mood / vibe: {{VIBE}}
TASK
Write a single image-generation prompt (one paragraph, ready to paste into an AI image tool) that describes:
1. The product in 3D: {{FORMAT}}, shown at a slight three-quarter angle so it reads as solid and real.
2. The exact cover text: the title "{{LEAD_MAGNET_TITLE}}" as the dominant element and "{{SUBTITLE}}" smaller beneath it, both clearly legible and correctly spelled.
3. A cover design that fits a {{NICHE}} audience, using {{COLORS}} and a {{VIBE}} mood.
4. Soft, realistic studio lighting with a gentle shadow grounding the product.
5. A clean, uncluttered background (solid or subtle gradient) with empty space around the product for landing-page copy.
6. A square 1:1 composition at high resolution.
CONSTRAINTS
- Photorealistic mockup style, not a flat illustration or clip-art.
- No people, no hands, no logos other than the title text.
- No extra words, gibberish text, or watermarks on the cover beyond the title and subtitle.
- Keep it tasteful and uncluttered; negative space matters more than decoration.
After the prompt, give me: (a) one alternative version with a different background color, and (b) a short list of negative-prompt terms I can add if my tool supports them.
How to customize it
Replace the six {{VARIABLES}} before you send it:
| Variable | What to put | Example |
|---|---|---|
{{LEAD_MAGNET_TITLE}} |
The exact title for the cover | The 7-Day Calm Plan |
{{SUBTITLE}} |
A short promise under the title | Beat burnout without quitting your job |
{{NICHE}} |
Your coaching niche | stress and burnout coaching for working parents |
{{FORMAT}} |
The object to mock up | a hardcover book standing upright |
{{COLORS}} |
Your brand colors | deep teal and warm cream, with a soft coral accent |
{{VIBE}} |
The mood | calm, premium, reassuring |

Here is the exact prompt, filled in for a burnout coach. This is the whole input, nothing hidden:
You are an expert brand designer and product-mockup specialist for coaches. Your job is to write ONE detailed image-generation prompt that produces a clean, professional 3D mockup of my lead magnet, ready to drop onto a landing page or opt-in form.
Before writing the prompt, ask me up to 3 clarifying questions if anything below is unclear or missing (for example: cover text length, orientation, or background). Otherwise, proceed.
CONTEXT
- Lead magnet title (goes on the cover): The 7-Day Calm Plan
- Subtitle or promise: Beat burnout without quitting your job
- My coaching niche: stress and burnout coaching for working parents
- Physical format to mock up: a hardcover book standing upright
- Brand colors: deep teal and warm cream, with a soft coral accent
- Mood / vibe: calm, premium, reassuring
TASK
Write a single image-generation prompt... [rest of the prompt unchanged]
And here is the complete output the model returns:
A couple of quick checks before I write your prompt:
- Should the title appear on one line or stacked across two? (It reads cleaner stacked.)
- Do you want the book photographed on a surface, or floating?
- Plain background or a soft gradient?
If you’re happy to let me decide, here’s the prompt with sensible defaults (title stacked over two lines, book resting on a soft surface, subtle gradient background):
Image prompt:
“Photorealistic 3D product mockup of a hardcover book standing upright, shown at a slight three-quarter angle so the spine and cover both read as solid and real. The front cover displays the title ‘The 7-Day Calm Plan’ as the dominant element, stacked over two lines in a clean modern serif, with the smaller subtitle ‘Beat burnout without quitting your job’ beneath it; all text crisp, legible, and correctly spelled. The cover design suits a stress and burnout coaching audience of working parents: a deep teal background with warm cream typography and a single soft coral accent line. Soft, realistic studio lighting from the upper left, with a gentle natural shadow grounding the book on a smooth cream surface. Clean, uncluttered subtle teal-to-cream gradient background with generous empty space on the right for landing-page copy. Calm, premium, reassuring mood. Square 1:1 composition, high resolution.”
(a) Alternative version — lighter background:
“…identical to above, but place the book on a soft warm-cream background with a faint coral gradient in the lower corner, keeping the teal cover as the visual anchor.”
(b) Negative-prompt terms (if your tool supports them):
people, hands, faces, extra books, cluttered desk, gibberish text, misspelled words, watermark, logo, low resolution, flat 2D illustration, clip-art, harsh shadows, busy background.
That is publish-ready. Paste the image prompt into your tool, generate two or three, pick the cleanest, and drop it on your opt-in page.
Why this works
Three LLM and prompting principles are doing the heavy lifting here. Learn them and every image prompt you write gets better:
- Role priming. The opening line (“You are an expert brand designer and product-mockup specialist for coaches”) tells the model which slice of its knowledge to use. “Make me a book image” pulls the bland internet average; “act as a mockup specialist” pulls the language designers actually use: three-quarter angle, studio lighting, grounding shadow. Always assign a role.
- Specificity in, specificity out. An image is only as good as the words describing it. “A nice ebook cover” gives you a random gradient and fake text. Naming the exact title, the format, the colors, and the composition (1:1, negative space on the right) means the model has nothing left to guess. The detail you put in is the polish you get out.
- Constraints are quality control. The “no people, no gibberish text, no watermark” lines aren’t filler. AI image tools fail in predictable ways, mangled cover text and random clutter being the worst, so naming what NOT to render heads those failures off. And the “ask up to 3 clarifying questions first” line lets the model fill real gaps (one line or two? floating or resting?) by asking instead of guessing, which is the single biggest fix for generic AI output.
Do this now
- Copy the prompt above into ChatGPT, Claude, or Gemini.
- Replace the six variables with your real title, subtitle, niche, format, colors, and vibe.
- Answer the clarifying questions, then paste the image prompt it gives you into your image tool.
- Generate two or three, pick the cleanest, and put it on your opt-in page today.
Pro tips
- Generate, don’t settle. Run the image prompt 2-3 times. AI mockups vary; the best of three is almost always landing-page ready.
- Check the cover text first. If the title is misspelled or garbled, regenerate before anything else; viewers forgive a plain background but not broken text.
- Match the format to the promise. A short checklist looks honest as a flat sheet or tablet screen; a deep guide earns a thick hardcover. Mocking up a 3-page PDF as a 300-page book reads as overpromising.
- Save your winning prompt. Once a mockup style works for your brand, reuse the same wording for every future lead magnet so your visuals stay consistent.
