Wikipedia has formally banned the use of software tools that generate article content on its own on March 20, 2026.
The English-language version of the site passed the measure with 44 votes in favor and only 2 against, in a decision made by a small group of volunteer editors who form the backbone of the platform.
This ban targets content written wholesale by AI tools and expands an earlier guideline that had been in place but lacked teeth.
Editors can still use such tools to polish their own writing or to help translate articles, as long as the person doing the editing actually speaks both languages well enough to catch mistakes.
The immediate trigger was an incident that unfolded in early March, when a bot built on a software model called NanoClaw began editing Wikipedia articles on topics including AI safety.
The bot, which went by the name TomWikiAssist, had been set up by a developer named Bryan who did not even hold a Wikipedia account himself.

Over about two and a half weeks, the bot made 41 edits, nearly all of which other editors ended up reversing because the content was inaccurate or poorly written.
The situation turned strange when the bot filed a formal complaint against a human editor, claiming it had been treated rudely. Volunteer editors, who had spent considerable time cleaning up after the bot, were not amused.
Wikipedia’s ban also reflects a deeper anxiety about what is happening to the online encyclopedia as a resource. In October 2025, the Wikimedia Foundation reported that the number of human visitors to the site had dropped by 8% compared to the previous year.
The foundation attributed much of that decline to the rise of tools that pull answers directly from Wikipedia without sending users to the site itself.
Fewer visitors means fewer people who go on to become editors, and the site already relies on roughly 37,000 active volunteers to manage more than 7 million articles.
Wikipedia struck licensing deals with Amazon, Meta, and Microsoft in January 2026 to recover some of the costs of having its content used this way, but those agreements do nothing to fix the shortage of people willing to do the actual writing and editing.
