The Wikimedia Foundation, the nonprofit organization that hosts Wikipedia, says that it's seeing a significant decline in human traffic to the online encyclopedia because more people are getting the information that's on Wikipedia via generative AI chatbots that were trained on its articles and search engines that summarize them without actually clicking through to the site. 404 Media: The Wikimedia Foundation said that this poses a risk to the long term sustainability of Wikipedia. "We welcome new ways for people to gain knowledge. However, AI chatbots, search engines, and social platforms that use Wikipedia content must encourage more visitors to Wikipedia, so that the free knowledge that so many people and platforms depend on can continue to flow Sustainably," the Foundation's Senior Director of Product Marshall Miller said in a blog post.

Wikipedia volunteer Grnrchst uncovered a decade-long campaign that created articles about composer David Woodard in 335 languages. The investigation identified 200 accounts and IP addresses systematically creating Woodard articles across 92 languages between 2017 and 2019, averaging one new article every six days. From December 2021 through June 2025, 183 unique accounts each created a single Woodard article in different languages after establishing credibility through unrelated edits. Wikipedia stewards removed 235 articles from smaller wikis. Larger Wikipedia communities banned numerous accounts and deleted 80 additional articles. Twenty Woodard articles remain. Grnrchst called it "the single largest self-promotion operation in Wikipedia's history."
