Summary
Community Notes, initially known as Birdwatch, is a community-driven content moderation feature on X (formerly Twitter) designed to add context and fact-checks to posts, images, and videos. It operates on a crowd-sourced system, where notes are applied to potentially misleading content by an algorithm that prioritizes agreement from users across the political spectrum, rather than simple majority rule. The program, launched in 2021 and becoming widespread on X in 2023, aims to counter propaganda and misinformation. As of November 2023, it had approximately 133,000 contributors, with notes reportedly receiving tens of millions of views daily. While X owner Elon Musk considers it a "game-changer," the program has faced criticism regarding its potential to spread disinformation, vulnerability to manipulation, and inconsistent application. Notably, Meta, under Mark Zuckerberg, has also decided to embrace Community Notes from X, moving away from its previous reliance on third-party fact-checkers.

Community Notes, formerly known as Birdwatch, is a feature on X (formerly Twitter) where contributors can add context such as fact-checks under a post, image or video. It is a community-driven content moderation program, intended to provide helpful and informative context, based on a crowd-sourced system. Notes are applied to potentially misleading content by a bridging-based algorithm not based on majority rule, but instead agreement from users on different sides of the political spectrum. The program launched on Twitter in 2021 and became widespread on X in 2023. Initially shown to U.S. users only, notes were popularized in March 2022 over misinformation in the Russian invasion of Ukraine followed by COVID-19 misinformation in October. Birdwatch was then rebranded to Community Notes and expanded in November 2022. As of November 2023, it had approximately 133,000 contributors; notes reportedly receive tens of millions of views per day, with its goal being to counter propaganda and misinformation. According to investigation and studies, the vast majority of users do not see notes correcting content. In May 2024, a study of COVID-19 vaccine notes were deemed accurate 97% of the time. Critics have also highlighted how it has spread disinformation, is vulnerable to manipulation, and has been inconsistent in its application of notes, as well as its efforts in combating of misinformation. Some suggest that structurally the system "lacks critical reflection on the potential for content to harm". Elon Musk, the owner of X, considers the program as a game changer and having considerable potential. However, after a post by Musk received a Community Note, he claimed the program had been manipulated by state actors.

- Community Notes: A New Way to Add Context to Posts
Community Note contributors can write and submit a note on posts that they think are potentially misleading or confusing. A community note may include background information, a tip or an insight people might find useful. For a note to be published on a post, people who have previously disagreed on note ratings in the past will have to agree that a note is helpful. Notes will not be added to content when there is no agreement on the helpfulness of a note or when people agree a note is not [...] As we announced in March 2025, Meta has rolled out a Community Notes feature that lets people add more context to Facebook, Instagram and Threads posts that are potentially misleading or confusing. Meta has always been clear that we don’t think we should be the arbiters of truth, and our approach has long been to surface information that people find helpful in deciding what to read, trust or share. Beginning in the United States, instead of relying on third-party fact-checking organizations, we [...] Community Notes identifies when there is agreement that a note is helpful among contributors that normally disagree with each other. This system only takes into account each contributor’s rating history. We think this approach helps ensure that notes reflect a range of perspectives and reduces the risk of bias. Community Notes contributors decide what notes get written and how they are rated — not Meta. Image 16Impact on posts
