Wikipedia has introduced a new policy prohibiting editors from writing or rewriting articles using artificial intelligence. The update, added to the English version’s guidelines late last week, cites repeated violations of core content policies by AI-generated text as the reason for the ban. Editors may still use large language models for basic copy editing or translation, provided the AI does not add new content and the editor can verify translation accuracy.

The updated rules caution that some editors may naturally write in styles similar to AI, and enforcement should focus on compliance with content policies rather than stylistic traits. The change follows months of community concern over AI-generated material, which led to the creation of WikiProject AI Cleanup and a policy enabling the rapid deletion of low-quality AI-written pages.

The proposal, introduced by an editor known as Chaotic Enby, received overwhelming support from the community. It aims to curb problematic AI use while preserving acceptable applications such as minor edits and verified translations.
