Since Elon Musk took over Twitter and transformed it into what it is today, "Community Notes" have become a core mechanism for the platform to combat fake news and misinformation. However, relying entirely on human writers and moderators often proves insufficient in addressing the root causes of the problem.
To improve efficiency, X confirmed that it is conducting a new experimental feature called "Collaborative Notes," which will allow the Grok AI model behind X to write the "first draft" of notes, which will then be revised and graded by human contributors.
Humans order food, AI serves it.
According to X officialAnnouncement of informationThis new feature will change the workflow of community notes. Previously, when a post needed to be tagged, contributors had to write the content from scratch and include the source. In the experiment of "collaborative notes," when an eligible contributor requests notes for a post, the system will automatically generate a draft note using AI.
This draft, quickly generated by AI, is not the final version. Human contributors can rate it, suggest modifications, or add additional information. X stated, "When new suggestions and ratings are received, the system reviews the input and determines whether it can make the notes more helpful, thus deciding whether to update the note version."
Grok joins the battle, aiming for speed and accuracy.
Keith Coleman, a senior executive at X responsible for overseeing community notes, stated that the AI model behind this experimental feature is Grok. Many X users are already accustomed to tagging @grok in discussion threads to request fact-checking. Coleman pointed out that if this experimental feature is successful, this "suggestion-feedback" loop mechanism may be opened to AI note writers on the API platform in the future.
Yes, AI note writers are prolific. One writer has written over 1000 Helpful notes(!!). Further, their notes are mostly incremental on top of human-written notes, so already a substantial boost to the number of notes showing on X. We haven't even opened AI writing to non-English…

Why introduce AI?
• speed:The most common criticism of social media notes is that they are "too slow," often arriving late by the time misinformation has spread across the internet. AI, on the other hand, can generate a draft in seconds, significantly reducing reaction time.
• Training the model:Keith Coleman emphasizes that this is a process of making the model "smarter." Through continuous revision of the AI drafts via human interaction, Grok learns higher-quality logical and factual judgment abilities (i.e., RLHF's reinforcement learning mechanism based on human feedback).
Currently, this feature is only available to senior contributors with the "Top Writer" status, but the testing scope is expected to be gradually expanded in the future.
