X Pilots AI Note Writers for Fact-Checking

Elon Musk's X (formerly Twitter) is piloting AI-powered 'Note Writers' to generate Community Notes in an effort to accelerate and scale its crowdsourced fact-checking system. AI-generated notes must pass a consensus-based vetting process involving diverse human reviewers before publication. X claims that combining AI and human oversight will improve information quality and trust, but experts warn of risks such as AI 'hallucinations,' persuasive yet inaccurate notes, and the potential for manipulating public opinion or amplifying conspiracy theories. All AI notes will be clearly labeled for transparency. This initiative is part of a wider industry shift, with platforms like Meta and Google moving away from traditional human fact-checkers toward community or AI-driven moderation. The effectiveness and reliability of this approach remain uncertain as it is introduced to X's 600 million users.
