Wikipedia Bans AI-Written Articles, Limiting AI to Translation and Proofreading
Wikipedia editors banned writing articles with large language models in March 2026.
The rule applies to English Wikipedia, where a Princeton study found substantial AI-generated content in about 5 percent of nearly 3,000 articles created in August 2024.
Editors had initially tried to correct or remove weak AI text and fake sources, while some hoped AI could handle routine tasks.
They concluded AI-written content often violated Wikipedia’s core principles, so AI use was limited to translation and minor proofreading.
The concern is that fewer human contributors could leave more weak and inaccurate articles for editors to repair.
The Wikimedia Foundation says the care and commitment of its volunteers to reliable knowledge cannot be replaced by AI, but the story gives no further planned steps.
Wikipedia banned writing articles with large language models by March 2026, restricting AI use to translation and minor proofreading.
A Princeton University study found that about 5 percent of nearly 3,000 new English Wikipedia articles in August 2024 contained substantial AI-generated content.
Wikipedians found AI-generated material that included generic text and fake sources.
The policy followed concerns that AI content often violated Wikipedia’s core principles.
The article says the Wikimedia Foundation had been preparing for AI’s effects before the technology became widespread.

This story does not have two clearly opposing sides.
Google was training AI to write “Wikipedia-like articles.
Then-Wikimedia Foundation head Katherine Maher wrote an op-ed warning that AI could cause harm without human involvement.
About 5 percent of nearly 3,000 newly created English Wikipedia articles contained a substantial amount of AI-generated content, according to a later study.
A Princeton University study reported its findings on AI-generated content in English Wikipedia articles.
Wikipedia banned writing with large language models and restricted AI use to translation and minor proofreading.

What people are saying
Too often, artificial intelligence is presented as an all-powerful solution to our problems, a scalable replacement for people.
The potential ‘whittling down’ each year of our pool of talented writers is the greatest threat to Wikipedia
