How to Spot AI-Generated ‘Slop Books’ Before You Buy
Poorly written fakes are everywhere online, sometimes mimicking the work of human authors

Key takeaways
- AI-generated copycat books may mimic real titles, undercut their prices and contain low-quality or inaccurate information.
- Parents and grandparents have unwittingly bought AI-generated children’s books, which often include awkward language and odd illustrations.
- Before buying, read sample pages for errors or nonsensical writing, check reviews and look for the Authors Guild’s Human Authored certification.
A few weeks after Liane Moccia’s herbal-medicine book, The Herbal Fertility Handbook, was published in the fall of 2025, two AI-generated, copycat versions appeared on Amazon. “They had the exact same title as mine,” says Moccia, 52, of Andover, Massachusetts.
Moccia and her publisher successfully petitioned Amazon to stop selling the imitators — apparent “AI-slop books” (low-quality books churned out with AI software) that were produced quickly to mimic her title as it rose in online sales rankings.

Priced to undercut Moccia’s well-researched guide, the AI-generated books were poorly written and looked odd. One had just four words printed per line. And the purported authors had gimmicky, earthy-crunchy names but didn’t seem to really exist when Moccia researched them online.
But the books also contained dangerous advice: “They recommended herbs that could cause birth defects or other problems,” says Moccia, a registered herbalist with the American Herbalists Guild who has years of training and experience. “It was outrageous.”
AI-slop books flooding online stores
Tens of thousands — or more — of these fakes have inundated online bookstores since consumer AI emerged in late 2022, says Paramveer Dhillon, an associate professor in the School of Information at the University of Michigan. Critics note that many AI-generated books are not only low-quality; they divert sales from human authors across genres, including children’s picture books, cookbooks, fiction and self-help guides.
“Scammers who create AI-generated books are trying to skim sales from human authors,” says attorney Mary Rasenberger, CEO of the Authors Guild, an advocacy group for writers. Meanwhile, she adds, “They’re dumbing down our culture, our arts, our storytelling.”
Popular booksellers Barnes & Noble and Bookshop.org publicly state that they do not sell AI-generated books. Books-A-Million notes if a book is AI-generated in the author field. Amazon requires that writers who use the self-publishing site Kindle Direct Publishing disclose whether their works are AI-generated or written with AI assistance, but the giant bookseller doesn’t indicate AI authorship on the sales pages of books.
In response to questions about AI-generated books sold on its site, Amazon offered this statement to AARP:
“We are committed to a bookstore that readers love and publishers and authors trust, with multiple safeguards we continuously strengthen to protect their experience. Our content guidelines govern which books can be listed for sale, and we take proactive and reactive measures to prevent, detect, and remove content that violates those guidelines, whether AI-generated or not. We continually monitor our store and enhance these protections as technology and the publishing industry evolve.”
Amazon notes that customers can report any problems with a title by clicking on “Report an issue with this product or seller” on the book’s page. Moccia, however, says that Amazon was unresponsive to her complaints until a local TV news station requested a comment from the company about the copycat books.
In an August 2026 study, Dhillon and a research team used AI-detection software to evaluate 14,419 self-published novels sold online and found that 1 in 5 contained a significant amount of AI-generated material (at least 25 percent of the book was written by AI). None were labeled as AI-written, says Dhillon, and “most are low quality.”
Yet, he adds, some had reached top-selling spots in genres like romance, science fiction and thrillers.
AI books aimed at kids — many personalized with a child’s name and image — are also booming, says Australian researcher Daozhi Xu, a fellow at the School of Humanities at Sydney’s Macquarie University who studies AI-generated children’s literature. Xu says these books often feature “spelling mistakes, inconsistent images, mismatches between text and illustrations, incoherent plots, a lack of tension or humor, and flat characters.”
How to avoid buying AI-slop books
Look closely at the covers and description. Check whether the listing is for the original book or a summary or ‘companion book,’ Kentucky’s Kenton County Public Library advises. Examine the cover art and author photo for odd details, such as missing fingers or a strange background.
Read sample pages online. Look for misspellings, sentences that don’t make sense and poor writing in general, Rasenberger suggests. “There’s a lot of tortured metaphor,” she says. “AI sometimes overdoes things.”
Check out the author. Search for an author’s website, biography or other published work. The absence of an online presence can be a warning sign, Rasenberger says.
Scan the reviews. Learn from remorseful buyers of AI-slop books, who may leave online reviews warning others.
Research book recommendations you see on social media. Preview the book and check its author rather than relying on an influencer’s endorsement, says Moccia, who notes that her book group suspected that a novel recommended by an Instagram influencer had been AI-generated. Personalized, AI-generated children’s books are also often marketed to parents and grandparents on social media.
Look for the Authors Guild’s Human Authored certification or logo. Search the title or author in the Guild’s Human Authored database, or look for the logo on the book or its sales page. Authors of more than 6,000 books have signed up, attesting that they used AI only minimally, such as to check spelling, grammar and punctuation, Rasenberger says.
