Are Big Publishers Using AI Book Covers? What It Means for Your Book
- ✓Wired reports that staff at HarperCollins, Simon & Schuster and Hachette have watched AI being used for cover copy, publicity and cover art, often without the author being told.
- ✓The tool is the smaller problem. The secrecy is the bigger one, and readers punish a book they suspect of hiding it.
- ✓When you self-publish, nothing lands on your cover without your say. Make that call deliberately and be open about it.
- ✓A raw AI image is usually too small, in screen colours and blind to your spine. A press exposes all three.
- ✓Let AI help with the thinking and sketching, then hand the finish to a designer and a proper typeface.
On 10 October 2026, Wired published a report built on conversations with more than two dozen people working inside the biggest publishing houses. Gizmodo ran with it the same day, under a headline that lands like a slap: as they supposedly battle AI slop, major publishers are reportedly covering their books in it.
We read it closely, because covers are what we handle all day. Ex Why Zed prints books for authors, artists and small presses, and self-published titles are the biggest single group in our portfolio of real print jobs.
We should also be honest about where we stand. Our own Artwork Hub gives authors copy and paste prompts for building press ready covers in ChatGPT and Claude. So this isn't a lecture about keeping machines away from books. It's the view from the people who put those covers on a press: what went wrong at the big houses, and how you can do better with your own.
What staff told Wired about AI inside the big houses
The report centres on HarperCollins, Simon & Schuster and Hachette. According to the employees Wired interviewed:
- Tools including ChatGPT, Claude and Jasper have drafted back cover blurbs, publicity material and pitches.
- Image generators have been used on cover art.
- Authors were frequently left in the dark.
- HarperCollins reportedly runs an internal "AI Champions" scheme, and Simon & Schuster reportedly dangled a $10,000 staff prize for AI ideas before easing off after complaints.
The publishers dispute parts of that picture. Hachette told reporters it supports AI for operational work that helps authors reach more readers. Simon & Schuster said staff may use a small number of vetted tools and that nobody is obliged to.
The timing is what makes it sting. In May, the Big Five jointly sued Meta, alleging copyright infringement in the training of its Llama models. Taking a tech giant to court over AI while quietly running your own covers through it is exactly the contradiction Gizmodo's headline went after.
These are claims from anonymous staff, reported by Wired and summarised by Gizmodo and IBTimes UK. Some of the detail is contested, so we've linked every source at the bottom of this page.
The silence bothers us more than the software
Picking up a tool is a choice. Using it on somebody's book without telling them removes that choice. A cover is the first promise a book makes to a reader, and the author's name is printed right across it. If an image generator made that promise, the author should know before the files go anywhere near a printer.
Readers notice, and they don't forgive easily. Minotaur Books, a Macmillan imprint, dropped a deal reported at around $2 million for the debut novel Call Me, I'll Hide the Body after fourteen bidders had chased it, because of doubts over whether the manuscript was written with AI. Deadline pointed out that AI elements can also tangle up copyright registration and chain of title. Suspicion on its own was enough to sink it.
Agents are now writing protection into their contracts. Some require publishers to promise they won't feed unpublished manuscripts into large language models to churn out marketing copy.
That's the real lesson for anyone printing their own book. You are the publisher, so the decision belongs to you, and so does the honesty. If AI made your cover art, say so in the credits, the same way you would credit an illustrator or a photographer. If it didn't, you're free to say that too, and plenty of readers now look for it. Our comparison of self-publishing and traditional publishing covers the other freedoms that come with owning the whole process.
Why a raw AI image prints soft, dull and short of a spine
Park the ethics for a moment and look at the file itself. The prompts on our Artwork Hub exist because AI artwork keeps tripping over the same three hurdles: wrong size, no bleed and words parked too close to the edge. A book cover adds a few more.
1. Resolution: the maths rarely adds up
Print wants roughly 300dpi at the size the picture will actually appear. An A5 front cover with 3mm bleed measures 154 × 216mm, which needs about 1,819 × 2,551 pixels. Plenty of image generators still hand back files somewhere between 1,000 and 2,000 pixels across. Stretch a 1,024 pixel square over that A5 front and you're printing at around 120dpi: fuzzy edges and smeared detail the second someone picks the book up. Upscaling software adds pixels, but it has to invent whatever goes in them.
2. Colour: made for a screen, printed in ink
AI images arrive in RGB, the colour space of glowing screens. Presses lay down CMYK inks. The electric blues and neon pinks that generators adore sit outside what those inks can reach, so they print flatter than you expect. Convert early and judge the cover in CMYK before you fall in love with it. Our explainer on whether print will match your screen shows why.
3. Spine and back cover: the generator only sees the front
A paperback cover is one long piece of artwork running from the back, across the spine, to the front, with bleed all round. Spine width depends on your page count and paper, which no image tool can guess. It won't leave a clear patch for your ISBN barcode either. Work the width out with our spine calculator, then build the full wrap from our cover templates.
4. Lettering: still the giveaway
Generators have got better at text, yet titles still come back with odd letterforms, lumpy spacing and the occasional bonus letter. Even when the spelling survives, generated type rarely carries the authority of a well chosen typeface set with care. Create the image without words, then set your title and name properly. Our guide to the best fonts for self-published books is a good place to start.
| Typical AI image | An A5 paperback cover ready for press | |
|---|---|---|
| Size | Often a square of 1,024 to 2,048px | About 1,819 by 2,551px for the front alone |
| Colour | RGB | CMYK |
| Bleed | None | 3mm on every edge |
| Spine | Missing | Exact width for your pages and paper |
| Type | Generated, often flawed | A real typeface, kept 5mm inside the trim |
Where AI earns its place on a cover project
We would never tell an author to ignore a tool that saves money and gets ideas moving. The knack is using AI where its weaknesses don't matter and keeping people where they do.
Sharpen the brief
Ask ChatGPT or Claude to help you describe your book, your readers and the covers you admire in your genre, then turn all that into a clear brief for a designer.
Sketch directions
Generate rough visuals to show what you mean. Treat them like doodles on a napkin, never as finished artwork.
Hire the finish
Take the brief and the sketches to a designer or illustrator. Our guides to finding a book designer on Fiverr or on PeoplePerHour, and to finding an illustrator for a self-published book, walk you through it.
Building it yourself?
Paste our exact prompt from the Artwork Hub. It tells ChatGPT or Claude your finished size, makes it add 3mm of bleed and keeps every word at least 5mm in from the trim.
Credit what you used
A line on the imprint page or in the acknowledgements is enough.
Our posts on using AI to illustrate a children's book and on using ChatGPT to print a children's book go deeper into that workflow.
A sun, a toad and a melting planet
Whatever tools sit behind a cover, the ones that work on a shelf commit to a single idea. Three from books we've printed:
None of these needed photorealism. Each one backs a single image and pairs it with lettering that suits the book. That focus is a design decision, and it's exactly what prompts tend to blur, because a generator leans towards the average of everything it has seen. If you want to train your eye, our six steps to mastering book cover design and our round up of twenty brilliant book covers are full of examples.
Paper and finish then do half the work. Matt lamination keeps soft watercolour tones calm and free of glare, while a cloth hardback stamped in gold foil, like the Victorian Writers Then and Now title we printed, gives a literary book weight before anyone turns a page. No image file can choose those for you.
Every file we print gets a human look first
Here's our 2p in practical form. Whatever made your cover, a real person at Ex Why Zed opens the file before it goes near a press, and the check costs nothing. We look at size, bleed, resolution, spine width and where your words sit, and if something is going to print soft or dull we say so plainly and help you put it right.
You can order a single copy and hold the finished cover before you commit to a full run. Paperbacks reach you in around five days, hardbacks from seven, and UK delivery is free. Our book printing service has the full details, and our self-publishing book printing page walks through formats and bindings.
Made your cover with AI, a designer or a bit of both? Send it over and we'll tell you honestly how it will print.
Send us your cover →Questions authors are asking us about AI covers
Yes. Nothing stops you, and we'll print it like any other file. Sales platforms set their own rules, though. Amazon KDP, for example, asks you to declare AI generated content, images included, when you publish. Check the current terms wherever you plan to sell.
That depends on where you live and how much of the work is yours. In the US, the Copyright Office has refused to register images made entirely by AI, and UK law on the question is under review. We're printers, not lawyers, so if rights matter (selling translation or film rights, say) get proper advice. Commissioning an illustrator with a clear licence sidesteps the issue.
Aim for 300dpi at the finished size, bleed included. For an A5 front, that means at least 1,819 pixels wide by 2,551 tall. Our Artwork Hub lists page sizes with the bleed already added.
Yes. We check it by hand like any other file and tell you if the resolution, colour or bleed needs attention before anything is printed.
