## Summary

Tuhin Chakrabarty, a computer scientist at Stony Brook University, studies how to identify AI-written text. His team analyzed 200 AI-flagged books, 200 self-published bestsellers, and 200 literary fiction titles from Amazon. They found AI-generated books contained the most verbatim overlaps with existing works, often repeating rare expressions or narrative beats from prior books. Chakrabarty argues this pattern—especially in genre fiction—suggests AI struggles with originality but excels at replicating formulaic tropes. His work was cited in claims that *Daggermouth*, a 2026 bestseller, used AI, though the author denies it. Chakrabarty shared data with *The Atlantic* but avoided naming authors due to legal risks, noting that AI detection tools like Pangram flagged over half of *Daggermouth* as AI-generated, though he disputes it being fully AI-written.

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.

## 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

## Why it matters

This work could shape debates over copyright, authenticity, and AI’s role in creativity, while detection tools may pressure authors to disclose AI use.
