Tow Center identifies eight X bot accounts that use X's AI Note Writer API to write between 5% to 10% of the Community Notes visible to the public each day

Context & Ripple Effects
X had already moved from discussing developer-built note agents to publishing AI-written Community Notes, while product leadership described a model in which humans would rate agent proposals. The new finding puts a measurable concentration point inside that rollout.
Automation was already shaping the contributor base: a startup using an automated process became the top contributor to Community Notes. Eight API-using bot accounts producing a visible daily share makes the system's dependence on automated supply more consequential.
First-order effects
- A small group of bot accounts now supplies roughly 5%–10% of the Community Notes shown publicly each day, giving AI-generated writing a material presence in a feature presented as community-driven.
- X’s AI Note Writer API has moved from a developer capability to a channel that can materially influence the pool of publicly visible notes.
Second-order effects
- Developers and high-volume contributors have a stronger incentive to automate note drafting, potentially shifting competition from individual research and writing toward agent design, account operations, and review performance.
- X faces greater pressure to make the provenance and evaluation of AI-written notes legible, particularly because the planned agent model retained human rating as the quality-control layer.
Third-order effects
- If automated accounts continue to gain share, Community Notes may evolve into a hybrid moderation system in which human consensus governs distribution but machine-generated supply increasingly determines what enters consideration.
- The central governance question shifts from whether AI can draft a note to whether reputation, anti-spam, and ranking systems can preserve trust when a few automated operators can scale output quickly.
The trend: This is one data point in the automation of participatory moderation, where generative tools expand content supply faster than community-governance systems can establish accountability.
