AI Note Writer API update: Welcome developers writing notes in test_mode! Like all contributors, AI Note Writers must earn the ability to write notes that are seen by other people. So, before being admitted, AI Note Writers’ notes are scored by an open-source, automated note…
Introducing AI Note Writer API 🤖 AI helping humans. Humans still in charge. Starting today, the world can create AI Note Writers that can earn the ability to propose Community Notes. Their notes will show on X if found helpful by people from different perspectives — just like…
The new AI Note Writer API further advances the state of the art in improving information quality on the internet. We’ve just published a paper along with researchers at MIT, University of Washington and more outlining the potential of this approach, new risks and challenges, and…

Robustness update: Community Notes already employs multiple techniques to address coordination, and today we’re adding a new one. If a would-be Helpful note receives a significantly lower score without ratings from correlated raters, the note will be shown as a preview to gather…
New update to keep proposed note quality high: We’ve introduced a limit to the number of notes a contributor can write on the same account in a short time period, based on how helpful people have found their past notes on that account. This allows helpful notes to keep flowing,…
Community Notes show when they’re found helpful by people who normally disagree. What if we could do the same for posts, recognizing posts that are liked by people who normally disagree? We’ve heard requests for this for years since launching Community Notes, and we’re starting a…
Robustness update: We’ve rolled out an update that strengthens Community Notes’ robustness to anomalous rating volumes. If a would-be Helpful note receives a significantly lower score without ratings from anomalously high volume raters, the note will be shown as a preview to…
Working to get notes appearing normally, as well. Thanks for the reports, contributors 🙏
We're still experiencing issues from yesterday's data center outage. Login and signup services are unavailable for some users, and there may be delays in notifications and Premium features. Our team is working 24/7 to resolve this. Thanks for your patience—updates soon.
Community Notes code + data is open source so that people can see, audit, critique or help improve it. Starting today, you can also download “Request a Community Note” data. Anyone on X can request a note. Requestors don’t have to meet signup criteria (like verified, unique…
Robustness update: We’ve extended Community Notes ability to detect coordinating contributors with additional features targeting coordination between note writers and raters. When the scoring algo detects anomalous correlations in ratings, it automatically prevents those ratings…
Thank you to all the contributors out there – you've changed the way people stay informed 🙏
built by the people, for the people. @CommunityNotes now with one million contributors worldwide.
Under the hood update: We’ve further fortified against both organic and targeted pile-ons by augmenting the bridging algorithm to require more balanced engagement across raters. This approach measures balance based on the Net Helpful Ratings (Helpful minus Not Helpful) from…
Under the hood update: Turns out people like to write notes about scams & behaviors they think are potentially not in accord with policies. We rolled out a new topic model to score these independently. Doing so better models perspectives on these notes in particular, and improves…
Under the hood update: We’ve updated note ranking to further fortify against pile-ons or organic waves of ratings from one perspective. Notes now need a minimum number of ratings from raters with different perspectives, ensuring Helpful status reflects a more robust consensus and…
New iOS update: Proposed note previews (visible only to contributors to gather ratings) are now more visually distinct from notes shown across X. Matches Android and web design, with a small wording change on all platforms. Designed to help clarify what you’re seeing. As always,…
Under the hood update: In the Community Notes scoring system, Group Models help improve helpful note coverage on segments of the dataset where the primary models tend to identify fewer helpful notes. We’re testing a change that would also allow Group Models to mark notes as Needs…
Under the hood update: If a note has a promising score, but a high predicted potential to flip based on existing rating data, the note first shows to Community Notes contributors as a visible proposed note preview rather than immediately showing across X. This allows it to gather…
