Publishing Industry Grapples With AI Detection as False Accusations Threaten Author Careers
Hachette cancelled the U.S. and U.K. release of horror novelist Mia Ballard's debut novel Shy Girl after a New York Times report accused her of using generative AI to write it. Ballard denied the charge but acknowledged an editor on the self-published version might have used AI tools. The incident has divided the publishing industry and exposed a core problem: AI-detection software is unreliable, yet publishers are using it to make career-ending decisions.
The scandal arrives as literary professionals face a practical crisis. Agents, editors, and self-publishing platforms are drowning in AI-generated submissions. Kobo, a Canadian e-book company, rejected nearly 45 percent of books submitted to its self-publishing program in 2025-about 80 percent of those rejections were due to suspected AI generation, compared to barely any in previous years.
The number of self-published fiction titles in the U.S. jumped from 306,781 in 2024 to 477,104 in 2025, according to Bowker, the leading information agency for the books industry. The surge suggests AI tools have lowered the barrier to publishing.
The Detection Problem
Cecilia Lyra, a Toronto-based literary agent, now spends more time filtering submissions. She suspects some are AI-generated but acknowledges the burden falls on her to read enough of each submission to make that call. "It's my job to filter it," she said. "It has become more time-consuming, but I honestly think that that is just something that, as an agent, I have to accept."
The Ballard case illustrates why agents and publishers are nervous. AI-detection tools are imperfect. Some in the industry argue that Hachette's decision to cancel her book without standing behind its own editorial process was premature.
John Degen, president of the Writers' Union of Canada, said he would have preferred Hachette to defend the work. "The best AI detector in the world-the best detector of bad writing-is a good editorial process," he said.
A Distinction Between Types of AI Use
Not all AI use in writing is the same, and the industry is beginning to make distinctions. Completely AI-generated text-where an AI writes a manuscript from scratch based on a prompt-differs from AI-assisted writing, where a human author uses AI for tasks like spell-checking or editorial feedback.
Kindle Direct Publishing asks writers to declare any AI-generated text but allows AI-assisted works without restriction. IngramSpark, another self-publishing platform, says it will remove content generated by AI or "mass-produced processes" but does not flag AI-assisted work.
Chandler Supple, chief technology officer of River AI, a platform where writers use AI to edit and proofread, said the distinction matters. "People on our platform spend literally hundreds of hours working on these books," he said. "They're not just saying, 'Hey, Claude, can you write 200 pages for me?'"
About 20 percent of River AI's 20,000 users are Canadian, and many self-publish on the platforms above.
The Certification Route
One response to the uncertainty is certification. John Degen's forthcoming murder-mystery novel Seldom Seen Road will carry a "Human Authored" label developed by the Society of Authors, a U.K. trade union. The label operates on an honour system: authors declare their work was written without AI assistance.
"I really wish it wasn't necessary," Degen said. "But because it is necessary, I'm very proud to stand behind my work."
What Happens Next
Michael Tamblyn, CEO of Kobo, said the industry has not settled on how to address the problem. "Do people want to know whether the books are human written or not? And how do you go about that process of flagging or asking authors to certify or asking publishers to certifying?" he said. "That is far from being a settled issue right now."
Lyra, the literary agent, remains skeptical of claims that AI can match human creativity. "How? Explain to me how something that doesn't feel can write great story," she said. "I don't get it, I don't believe it. And I don't know if I'm right or not, but I know it's how I feel."
For writers navigating this moment, the safest path remains unclear. The industry is still building the rules as it goes.
