Editors using the visual editor will now see a warning when they paste text that is likely to have initially been copied from one of five external generative AI chatbots into Wikipedia. This feature is known as LLM Paste Check. It is a type of Edit Check that is community configurable. The check looks for markers in the copied HTML and is not using content watermark detection. Edits will also be tagged so that patrollers can review them more closely. The feature helps newcomers add content that respects Wikipedia’s policies and makes it easier for experienced editors to identify problematic edits. Communities with local policies about LLM usage can adjust the wording and policy that is linked. The team apologizes that this was rolled out without a delay for translations.
