Wikipedia Citation Needed is a Chrome extension developed by the Wikimedia Foundation's Future Audiences team. This experimental AI tool is designed to help users verify the accuracy of information found online, specifically on Wikipedia. By selecting a text passage while browsing, the extension uses the ChatGPT API to search Wikipedia for relevant articles and quotes, providing information on whether the claim is supported by Wikipedia. Users also receive article quality signals such as the date of the last edit and the number of references, enhancing the context of the information they encounter.

This extension aims to engage users in improving the quality of results by encouraging feedback through a provided link within the extension. Additionally, users can donate to Wikipedia after a certain number of verifications, supporting the non-profit organization that maintains Wikipedia and its associated projects.
