Background

The authors highlight a major impending change to the Community Notes ecosystem: the introduction of AI-authored notes. They explicitly state uncertainty about how this competition will affect human note authors.

Quantifying and characterizing these effects is essential for assessing the sustainability of human-driven contributions, potential shifts in incentives, and the broader dynamics of crowd-sourced moderation when AI and human outputs coexist.

During the preparation of this report, X announced their integration of AI-authored notes into Community Notes. It is not clear if this is a response to a perceived decline in human participation, nor is it clear how competition with AI-authored notes will affect human Note authors.
