Data source: X Community Notes public data. Please note X shares data with a lag and sometimes inconsistently. This chart is updated at least once a week, provided data is available.

Notes are classified into four author types. X's AI writers are the AI note-writing accounts operated by X: the six accounts running X's open-source Community Writer and two earlier X development accounts, now inactive, all listed in the project's ACCOUNTS.md and in a thread by Community Notes engineering lead Jay Baxter. X identifies these accounts only by their public aliases; we matched each alias to its anonymized ID in the public data by opening notes from the data on X, where each note's page shows its author's alias, and confirming that the full note text matched. The full list is in community_writer_accounts.json. Read more about what this means in our analysis. Other AI writers are notes by all other users whose enrollmentState is apiEarnedIn in the userEnrollment file. AI + Human are collaborative notes (identified by isCollaborativeNote in the notes file), which are initiated by AI at the request of high-impact users and then refined by human contributors; X runs these through a separate account. Human covers all remaining notes. A note is counted as "helpful" if its currentStatus in the noteStatusHistory file is CURRENTLY_RATED_HELPFUL. The date used is the note's creation date.

The AI share line includes X's AI writers, other AI writers and AI + Human notes.

The most recent day in the dataset is excluded from statistics and chart data as it is typically incomplete; peak AI share is calculated only from complete days. Please note that the last day will typically see a dip in helpful notes compared to the trend because it takes some time for notes to reach that status.

A small share of notes (~5%) that appear as helpful in the status history file are absent from the notes data files, perhaps because they were later deleted or removed by X. These notes are excluded from the tracker.
