The share of new online articles and listicles primarily written by AI has plateaued at around 50%, according to an analysis by digital marketing agency Graphite. This level has held steady for more than a year, following a rapid rise after the launch of ChatGPT. The findings are based on a sample of over 55,000 English-language web pages.
Facts First
- AI-generated articles account for ~50% of new online content, a share stable for over a year.
- The proportion rose rapidly after ChatGPT's 2022 launch, from 35.9% within one year to 48% within two years.
- Analysis sampled 55,400 URLs from the Common Crawl web archive, filtered for articles and listicles.
- Three AI-detector tools—Pangram, GPTZero, and Copyleaks—were used to classify content.
- An article was classified as AI-generated only when most of its text was detected as AI-written or AI-assisted.
What Happened
An analysis by digital marketing agency Graphite found the share of new online articles, blog posts, and listicles that are primarily AI-generated has remained near 50% for more than one year. This follows a significant increase after the launch of ChatGPT in November 2022. Within one year of the ChatGPT release, primarily AI-generated articles accounted for 35.9% of new online articles. Within two years, that share reached 48% of new articles. Since early 2025, the share has hovered at approximately 50% of new articles.
Graphite's analysis was based on an average of three AI-detector tools sampling URLs from Common Crawl, a large public archive of the web used in AI research and training datasets. The agency randomly sampled 55,400 English-language URLs from Common Crawl. The sampled pages were at least 100 words long, had publish dates between January 2020 and March 2026, and were classified as articles or listicles. Graphite used three AI-checking tools—Pangram, GPTZero, and Copyleaks—to analyze the articles. The agency classifies an article as primarily AI-generated only when most of its text is detected as AI-written or AI-assisted.
Why this Matters to You
The content you read online is now just as likely to be written by an AI as by a human. This could affect the quality, originality, and reliability of the information you encounter daily, as AI-generated content may lack nuanced human perspective or could be optimized for engagement over accuracy. For writers and content creators, this shift may reshape job markets and required skills, potentially increasing demand for AI oversight and editing roles.
What's Next
The plateau at 50% suggests a new equilibrium in online content production may have been reached, at least for now. Further developments in AI technology or changes in how platforms and readers value human-authored content could shift this balance. The methodology, relying on detector tools, may also evolve as AI writing becomes more sophisticated and harder to distinguish.
