How Much of the Internet Is Written With AI?; Pew Research Center, August 20, 2026

 SAMUEL BESTVATER, AARON SMITH, CARSON TERBUSH, CHRIS BARONAVSKI AND JANAKEE CHAVDA, Pew Research Center; How Much of the Internet Is Written With AI?

"In November 2022, OpenAI released ChatGPT to the public for the first time. Less than four years later, around half of U.S. adults say they use chatbots powered by artificial intelligence, including 24% who say they use them daily. These tools’ ability to generate human-sounding text has raised a basic question about the modern web: How much content online is now written by AI rather than by other people?

To explore this question, we used the Common Crawl web archive to collect almost half a million English-language webpages from the past five years – starting a couple of years before the release of ChatGPT. We then ran the text of those pages through an AI detection tool called Open Pangram to see how many of them were likely written or substantially edited by AI."
