Wikipedia has prohibited the use of AI tools such as ChatGPT for writing or rewriting articles. The Wikimedia Foundation confirmed on March 26, 2026, that the new policy only applies to the English version of the site. This is a major change in how the world’s largest encyclopedia handles content created by AI.
Administrators decided that because AI-generated text often clashes with the core rules on which Wikipedia was built. According to the policy announcement, large language models can produce content that sounds plausible but is factually wrong or unsupported by the cited sources. The volunteer editing community argued that relying on AI undermines the site’s commitment to verifiability and neutral point of view—two pillars that have kept Wikipedia reliable for over two decades.
New rules for using AI on Wikipedia
The policy does not completely prohibit the use of AI, but it strictly prohibits using AI to create articles from scratch. Editors can still use AI tools to refine their writing, but with one catch: they must carefully check the output for accuracy. The official guidance warns that AI “can go beyond what you ask of them and change the meaning of the text such that the sources do not support it.”
The same rule applies to translation. AI can help translate articles from other languages, but the editor must be fluent enough in both languages to catch any mistakes. In both cases, the human editor takes full responsibility for what is published.
Wikipedia also clarified that this is not a one-size-fits-all rule across all language versions. Each Wikipedia community sets its own guidelines. The Spanish Wikipedia, for instance, has gone a step further and fully banned the use of large language models, with no exceptions.
The move is a direct response to the flood of AI-generated content that has appeared on the platform over the past few years. According to Engadget, they hope this policy sparks a broader “grassroots movement” in which online communities decide for themselves whether AI is welcome.
For readers, this means you can still trust that Wikipedia articles are written and reviewed by humans—not bots. While detecting AI text isn’t an exact science, the site’s network of moderators will continue to monitor pages, especially those that don’t get frequent traffic, to catch any slip-ups.
Key takeaways for editors and readers:
- AI doesn’t write articles. AI can’t write or rewrite entire articles.
- A few things don’t fit. AI can help with writing or translating, but only if a person is watching closely.
- Spanish Wikipedia has a total ban, but other language versions might do things differently.
- Moderators will use their judgment and community reports to identify AI-generated content.
In conclusion, Wikipedia has stated that while AI tools can be helpful, they cannot replace the human judgment that has shaped the website over the years. By imposing these restrictions, Wikipedia hopes to maintain its standing as a reliable, community-driven resource. The website’s creation by people, for people, instills confidence in it.
