The flood of AI-generated junk websites now has a dedicated detection system. NewsGuard, the browser extension that rates news source credibility, has partnered with startup Pangram Labs to build a tool that identifies websites pumping out AI-written content disguised as legitimate journalism.
Pangram's AI models scan entire domains looking for patterns that indicate content was generated by large language models (the same type of AI behind ChatGPT and Claude). When the system flags a site, NewsGuard's human analysts manually verify the findings, checking whether the site discloses its use of AI and whether the content could mislead readers into thinking a real person wrote it.
3,000 Sites Flagged, Hundreds More Every Month
The numbers are stark. The system has already flagged over 3,000 AI content farm sites, more than double what NewsGuard's team identified manually the prior year. And the problem is accelerating: 300 to 500 new AI content farms are appearing every month. During one two-month audit period, 141 major brands were found running ads on these made-for-advertising sites, meaning real advertising dollars are funding AI-generated misinformation.
Pangram was founded in 2023 by former Google and Tesla engineers, and the partnership reportedly went through six months of testing before launch.
Who Gets Access
The tool is available through direct licensing for advertisers and integrates with The Trade Desk, a major demand-side ad platform that brands use to place programmatic ads. A browser extension for consumers is also planned.
The advertising angle matters most here. Brands have a financial incentive to stop their ads from appearing on junk sites, and ad platforms face pressure to clean up their inventory. As Pangram's Max Spero put it, if AI content can't be reliably detected, every communication channel will be flooded with cheap, inauthentic material.
This is a practical response to a real and growing problem. The 300-500 new sites per month figure suggests AI content farms are being spun up faster than anyone can manually review them. Automated detection is no longer optional.
