Imagine you’re in a bookstore and you wander over to the fiction section. There, you find two shelves: one for human-written novels… and one for novels written by AI.
That future may not be as far off as you think.
Roughly 4 million books were published in the U.S. in 2025. That’s a more than a 32 percent increase from 2024, according to the trade magazine Publisher’s Weekly.
It’s unclear how many of those books were written by AI, in part because software used to detect it can be ineffective. And the literary waters were made even murkier by the fact that
at least 3 million of those 4 million books were self-published. That makes it even more difficult to know if they were written by human hands (er, minds).
That’s not to say the self-published portion of the industry is the only part where this tech is showing up. Hachette, one the largest publishers in the U.S.,
canceled one of its novels, “SHY GIRL,” after allegations that its author used AI to write it.
All this is marking a turning point for the publishing industry. How can authors ethically use this technology? And do readers really need new AI-authored books in a market already saturated with options?
