Covers, mockups and ad images, made in ChatGPT.

Make a cover, product photos on a tablet and phone, social posts and ad images for your digital product, all in one matching style. Fill in four answers and copy the prompts.

Takes
About an hour
Needs
A ChatGPT account and your product name
Costs
Nothing beyond your ChatGPT plan

By the end of this you’ll have a cover, a product photo, a post, a story and an ad image for your product, all in the same colours and the same look. Your answers below write every prompt for you.

What you’ll need.

Get these set up first. Everything below uses them.

Some of these are affiliate links. If you sign up through one, I may earn a commission, at no extra cost to you. See every tool I use.

01

Tell this page about your product

Your answers write every image prompt below. They stay in your browser and nobody else sees them.

Exactly as you want it spelled on the cover.
Keep it under ten words. Short text comes out cleaner.
Two to four colours. Hex codes are best, plain names work too.
Describe it. A font name helps but ChatGPT may not match it exactly.
Real images only. Every prompt here tells ChatGPT to leave out reviews, star ratings, income figures and "results" pictures. Your images show the product. Your real proof goes in your copy, where you can back it up.
02

Make your cover first

Every other image is built from the cover, so it sets the look for everything that follows.

  1. Open ChatGPT and start a new chat. Keep this one chat for all your product images.
  2. Copy your cover prompt below, paste it in and send it. You can also pick Images from the More menu first, then paste.
  3. Wait for it. Images can take a minute or two.
  4. Read every word on the cover, letter by letter. If anything is spelled wrong, see step 5.
  5. When you’re happy, download it. You’ll attach it to the next prompts.
Your cover prompt
Make a cover for my PDF guide.

- Title, spelled exactly: [PRODUCT NAME]
- Portrait, 2:3, like a book cover.
- The title is the biggest thing on the page and easy to read on a phone.
- One simple picture or shape that fits the topic. No people's faces.

STYLE (use this for every image)
- Colours: [YOUR COLOURS]
- Look: clean and minimal, flat colour, simple shapes, modern
- Clean, uncluttered, plenty of space around the main thing.
- No reviews, star ratings, testimonials, quotes from customers, income figures, screenshots of results or "before and after" claims anywhere in the image.
- Spell every word exactly as I write it. Add no other words.
Want options? Type: "Make 3 different versions of this cover in the same colours." Pick one and carry on with that one.
You’ve got a cover in your colours, with your title spelled right.
03

Put your product on a tablet and phone

A digital product is hard to picture. Showing it on a screen tells a buyer what they’ll actually get.

  1. In the same chat, attach your cover with the + button.
  2. Paste the product photo prompt and send it.
  3. Check the cover on the screen matches your real cover. If it’s changed, type: "Use my attached cover exactly. Don’t redraw it."
  4. Then attach the cover again and send the "what you get" prompt for a wider image, good for your sales page.
Product photo prompt
Use the cover I've attached. Keep it exactly as it is: same words, same colours, same layout.

Make a product photo of my PDF guide called [PRODUCT NAME].
- Show the cover on the screen of a tablet, with a phone beside it showing the same cover.
- The devices sit on a tidy desk in soft daylight, seen from slightly above.
- Square, 1:1.
- Nothing else on the screens. No app icons, no notifications, no extra words.

STYLE (use this for every image)
- Colours: [YOUR COLOURS]
- Look: clean and minimal, flat colour, simple shapes, modern
- Clean, uncluttered, plenty of space around the main thing.
- No reviews, star ratings, testimonials, quotes from customers, income figures, screenshots of results or "before and after" claims anywhere in the image.
- Spell every word exactly as I write it. Add no other words.
“What you get” prompt
Use the cover I've attached. Keep it exactly as it is.

Make a "what you get" image for my PDF guide called [PRODUCT NAME].
- Show the cover on a laptop screen in the middle, with a tablet and a phone around it.
- Lay it out like a neat flat lay, seen from above, with space at the top for a headline I'll add later.
- Landscape, 16:9.

You’ve got two product photos for your sales page and checkout.
04

Make your post, story and ad images

Each place you post wants a different shape. Asking for the right shape up front saves you cropping later.

  1. Attach your cover again and send the social prompt. You’ll get a square post and a story.
  2. Attach the cover once more and send the ad prompt.
  3. Look at each one on your phone, small. If you can’t tell what it is at that size, ask for the product to be bigger.
Post and story prompt
Use the cover I've attached as the reference for colours and look.

Make two images to announce my PDF guide called [PRODUCT NAME]:
1. A square post, 1:1. The cover on a tablet on the left, and on the right in big clear letters: [PRODUCT NAME].
2. A story, 9:16. The cover in the middle third of the frame. Keep the top and bottom fifth clear so the app's buttons don't cover anything.

STYLE (use this for every image)
- Colours: [YOUR COLOURS]
- Look: clean and minimal, flat colour, simple shapes, modern
- Clean, uncluttered, plenty of space around the main thing.
- No reviews, star ratings, testimonials, quotes from customers, income figures, screenshots of results or "before and after" claims anywhere in the image.
- Spell every word exactly as I write it. Add no other words.
Ad image prompt
Use the cover I've attached. Keep it exactly as it is.

Make an ad image for my PDF guide called [PRODUCT NAME].
- Portrait, 4:5.
- The product on a tablet and phone takes up most of the frame.
- No other words, no prices, no "limited time" badges, no arrows.
- It should still be clear what it is when it's the size of a thumbnail.

STYLE (use this for every image)
- Colours: [YOUR COLOURS]
- Look: clean and minimal, flat colour, simple shapes, modern
- Clean, uncluttered, plenty of space around the main thing.
- No reviews, star ratings, testimonials, quotes from customers, income figures, screenshots of results or "before and after" claims anywhere in the image.
- Spell every word exactly as I write it. Add no other words.
Running ads? Make two or three versions of the ad image with different backgrounds so you have something to test. Type: "Make 2 more versions with a different background colour from my palette."

Fix anything with an edit

You almost never need to start again. Tell ChatGPT the one thing to change and to keep the rest.

  1. Click the image you want to change.
  2. To change one part, use the select tool if you see it and highlight that area. Or just name the area in your message, like "the title" or "the plant on the left".
  3. To change the shape, use the aspect ratio option, or say the shape in your message.
  4. Always end with "Keep everything else the same."
Things you can type
Change only the title colour to the darker colour. Keep everything else the same.
The word "[PRODUCT NAME]" is spelled wrong. Fix the spelling and change nothing else.
Make this exact image again in 9:16 for a story.
Remove the plant on the left. Keep everything else the same.
Make the tablet bigger so it fills more of the frame.
Words coming out wrong? Long titles are the hardest part. Ask for one fix at a time. If a word still won’t come out right after two goes, ask for the image with no words and add the title yourself in any design or photo app.
06

Keep every image in the same style

When your cover, posts and ads match, people start to recognise your product before they read a word.

  1. Make every image for one product in the same chat, so ChatGPT can see what came before.
  2. Always attach your cover, or the last image you liked, and say: "Match the colours and look of the attached image."
  3. Paste the style block from your style sheet download under any new prompt you write yourself.
  4. Find any image again in the Library in the ChatGPT sidebar. Every image you make is saved there.
That’s it. A full set of product images in one look, and the prompts to make more.
07

Take your downloads

Tick what you want. Each file is written from your answers in step 1.

Your tools, one more time.

If something goes wrong.

The title is spelled wrong

Click the image and type: "The title should say [your title]. Fix the spelling and change nothing else." If it still won’t come right, ask for the same image with no words and add the title in any design or photo app.

The cover on the tablet looks different from my real cover

Attach your cover again in the same message and say: "Put my attached cover on the screen exactly as it is. Don’t redraw or change it."

Each image looks like a different brand

Go back to one chat, attach the image you like best and say: "Match the colours, lighting and look of the attached image." Paste your style block underneath.

ChatGPT says I’ve hit a limit

It tells you when you can make more images. Come back then, in the same chat, and carry on where you stopped.

It added a review or a number I didn’t ask for

Click the image and type: "Remove all reviews, stars, quotes and numbers. Keep everything else the same." Only use real proof you can back up, and keep it in your copy.

What’s next

Now put those images in front of buyers.
