AI Squeezes Writers' Income: Insights from 14,419 Novels, With About 20% of Books Containing Over 25% AI Content
A research team tested 14,419 Amazon best-selling novels and found that about 33% contain AI content, with 20% of books having over 25% AI content, raising concerns about the impact on writers' income.
A study on Amazon best-selling self-published novels reveals the extent of artificial intelligence penetration in literary creation. The research team randomly selected 14,419 novels from sales data between 2023 and March 2026 and analyzed the full text using detection tools from Pangram.
Data shows that about 33% of new books on the bestseller list contain AI-generated content. Among them, works defined as "substantial AI," meaning AI-generated text accounts for at least 25% of the book, make up about 20% of the sample.
This finding has sparked concerns about AI squeezing traditional writers' income. As AIGC technology matures, low-cost content production methods are changing the ecosystem of the publishing industry, particularly evident in the self-publishing sector.
Although detection tools provide quantitative evidence, the accuracy of AI detection and definition standards remain a focus of industry discussion. How to balance technical efficiency with human creative value in the future will be an important issue facing the publishing industry.
