book cover design

You need an ad for your book or a product launch, and there isn’t much money left for the design.

AI image generators can help you make artwork, explore branding ideas and plan product images without starting from a blank canvas.

The best one for marketing is the one that gives you usable images for your audience; a beautiful picture still needs to work inside the actual ad.

Best ai image generator for marketing

Start with what you need to make. A background for a book promotion is a different job from a logo you’ll put on everything your business sells. Don’t judge both by which tool makes the prettiest picture.

Midjourney, DALL-E and Stable Diffusion are examples of tools that turn text descriptions into images. That gives you a way to try visual ideas. It doesn’t make every result a finished piece of marketing.

I’ve spent hundreds of hours experimenting with Midjourney for personal projects and book cover ideas. Getting great art is exciting, but you can still screw it up with boring text or fonts that don’t fit the genre.

The art is only part of the job.

For an author, compare results against books your readers already buy. Does the image feel like a cozy mystery, or did you accidentally make a horror ad because the lighting looked cool? The same question applies to other products: does this look like something your customers would want?

My guide to AI book cover generators deals with the art and typography problem in more detail. I built a free AI book cover generator too.

If you’re choosing between PlayPlay Design and DALL-E for brand visuals, put the same real job in front of both before deciding. Compare what you can actually use, including the work left after generation. A pile of impressive samples isn’t much help if none of them fit your campaign.

Put your title on a cover. Then make it your own.

How to use ai image generation for branding

Decide what your brand should look like BEFORE asking for images. Otherwise you’ll keep changing direction whenever the generator makes something interesting.

Say you write cozy mysteries. You could explore warm interiors, village streets or illustrated objects. Those might all fit, but mixing completely different styles across every promotion won’t give readers much to recognize.

Make a moodboard first. Keep images that belong together, then use that selection to narrow your descriptions. You’re looking for a consistent feeling, not collecting every pretty thing the tool happens to make.

A prompt could be as simple as: “Illustrated village bookshop at dusk, warm light in the windows, muted blue and cream colors, empty sky above the building for text.”

That gives you something to work with.

You can explore logo ideas or packaging patterns the same way, but don’t get so attached to the first result that you stop looking at how it will be used; a complicated illustration might look amazing on your screen and look like crap when you squeeze it into the corner of an ad (where your logo actually needs to go).

Keep the design simple enough to repeat. If every image needs a completely different font treatment to make it work, go back and look at the images you’ve chosen.

What solutions create product imagery trained on my brand’s specific visual style guidelines?

If you need that level of consistency, ask for examples made to a specific brief. A tool producing an image in your chosen colors isn’t enough evidence that it can follow your whole visual style.

Give it an ordinary job from your business. Use the same product and the same visual direction across several proposed images. Then look at them together, rather than judging each one separately.

Do they belong in the same campaign? Is the product still the thing you wanted to show? How much would you need to fix before publishing?

Don’t pay for a promise of “on-brand” imagery without seeing what that means for YOUR brand. If the results keep pulling you toward a different look, that’s more design work for you, even if generating them was quick.

How to use an ai image generator on the web to create ad creatives

Work backward from the ad. Decide what you’re selling and what the image needs to communicate before writing the prompt.

For a seasonal coffee promotion, a steaming cup in a cozy winter setting is a reasonable starting point. You don’t also need the whole cafe, its history and every pastry on the menu.

  1. Choose the main subject. Give the image something obvious to focus on.
  2. Describe the setting and style. Keep these tied to the audience you’re trying to reach.
  3. Leave room for your headline. Don’t fill every corner with interesting stuff and then wonder where the words should go.
  4. Generate alternatives. Change the part that isn’t working instead of rewriting the entire idea every time.
  5. Add your text and look at the complete ad at the size people will see it.

You can use ChatGPT to help draft taglines, but “sounds clever” isn’t much of a standard. A reader should understand what you’re offering without needing an explanation.

And don’t make everything equally loud. If the picture, headline and logo all fight for attention, adding more effects won’t fix it. My rules of professional book cover design cover hierarchy and immediate visual impact; those are useful things to check in an ad too.

Product mockups and packaging ideas

AI is useful for seeing what a product idea might look like before you commit to it. Try different packaging directions, or explore a setting for a lifestyle image.

“Modern shampoo bottle with a floral label” gives you a starting concept. It doesn’t settle every decision about the actual bottle or packaging. Treat it as something to discuss and revise.

For authors, there’s an easier option when the cover is already finished. My free 3D book mockup tool turns your flat cover into a book image you can download as a transparent PNG or JPG. You don’t need to generate a new interpretation of a cover you’ve already designed.

Use images to plan a sales video

You can also generate scene ideas for a video. Start with the script, then make a rough image for each part that needs a visual.

This is especially useful for figuring out what belongs in the video before spending time assembling it. Keep the scenes tied to the same visual direction you chose for the campaign. A different style in every shot will give you the same problem as a mismatched moodboard.
