Wikipedia editors have published a guide titled 'Signs of AI Writing' to support readers and contributors in detecting AI-generated content across the encyclopedia.

The field guide distils key linguistic and formatting traits commonly found in AI output, such as overblown symbolism, promotional tone, repetitive transitions, rule-of-three phrasing and editorial commentary that breaks Wikipedia's standards.

The initiative stems from the community's ongoing challenge against AI-generated content, which has grown enough to warrant the creation of a dedicated project named WikiProject AI Cleanup.

Volunteers have developed tools like speedy deletion policies to quickly remove suspicious entries and tagged over 500 articles for review.

While the guide aims to strengthen detection, editors caution that it should not be treated as a shortcut but should complement human judgement, oversight, and trusted community processes. Such layered scrutiny helps preserve Wikipedia's reputation for reliability.
