Can scientists reliably tell if a novel is written using AI?

Tuhin Chakrabarty, a computer scientist at Stony Brook University, studies how to identify AI-written text.

They found AI-generated books contained the most verbatim overlaps with existing works, often repeating rare expressions or narrative beats from prior books. Chakrabarty…

Key points

  • Stony Brook researchers found AI-generated books repeat rare word sequences from prior works more than human-written ones
  • AI struggles with originality in literary fiction but mimics genre tropes and clichés in self-published books
  • Chakrabarty’s methods flagged *Daggermouth* as partially AI-written, but the author denies AI use and publishers defend the book

Chakrabarty emphasizes transparency: disclosing AI use in writing could clarify creative contributions. He contrasts AI’s role in plagiarism with its potential for creative collaboration, citing examples like Vauhini Vara’s Searches (2025) and Sheila Heti’s New Yorker story. His research highlights a growing challenge: distinguishing AI-assisted work from fully human creation, particularly as AI tools become more integrated into creative processes.
