X tested and deployed a program allowing AI bots to generate Community Notes — short fact-checking annotations added to posts — which are then reviewed and rated by human contributors before going public. The AI Note Writer program launched in July 2025.

X launched the AI Note Writers program in July 2025, enabling developers to build AI bots that can draft Community Notes in response to user requests. These AI-generated notes go through the same human consensus review process as notes written by human contributors — they must achieve agreement from users with historically differing perspectives before appearing publicly. By September 2025, AI-authored notes were appearing publicly. A Tow Center analysis (reported by Columbia Journalism Review in November 2025) found eight AI accounts writing between 5 and 10 percent of publicly visible Community Notes daily.
