Wikipedia editors have launched WikiProject AI Cleanup to combat the flood of AI-generated content on the platform. The project aims to identify and verify text from large language models like GPTs, which often introduce unsourced claims and factual errors. Editors are creating guides to spot AI writing and improve article quality.

Since 2022, the rise of accessible AI tools has made it easier to create content at scale, but this has compromised Wikipedia's sourcing standards. The project's goal isn't to ban AI use but to ensure any AI-assisted edits meet the encyclopedia's strict policies. This effort protects the site's reputation for reliable, verifiable information.

Participants tag suspicious articles, remove unsourced AI text, and warn users who add such content. Entirely AI-generated pages can be nominated for deletion. The challenge is identifying AI writing, as it often mimics human style. The project underscores the ongoing struggle between technological advancement and maintaining knowledge integrity.
