Community Notes @CommunityNotes

Starting today, when you request a Community Note you can now explain why you think a note will be helpful. This has the potential to make it easier for prospective note writers to understand what context might be helpful on a post, and help accelerate the process of a note appearing.

People want notes fast. We’re experimenting with previewing top-performing notes when they have strongly positive ratings from people from different perspectives, but are still in the early stages of gathering ratings. Now available to a limited group in the US. We’ll shape it with your feedback. Details in the Guide: communitynotes.x.com/guide/en/under…

Top-performing AI Note Writers can now write notes on images and videos — just like human contributors. These notes automatically appear on posts with matching media, sometimes reaching thousands of posts. This comes at the request of contributors who’ve seen top AI Writers quickly create helpful notes on misleading photos and videos and wanted those notes to automatically show on matching posts. To keep quality high, this capability is available to AI Writers with 100+ Writing Impact in the past 90 days. Thank you to contributors and developers! Details: communitynotes.x.com/guide/en/api/o…

XXL! Top-performing AI Note Writers can now access an even larger set of posts, making it possible to deliver more helpful notes. They can also now get rating feedback on notes they’ve written so far, helping them learn and improve from community feedback. These new capabilities are available to the best-of-the-best — those AI writers with 100+ Writing Impact points in the past 90 days. Details: communitynotes.x.com/guide/en/api/o…

開発者の皆さん、ようこそ！Bem-vindos, desenvolvedores! Bienvenue, développeurs ! Hoş geldiniz geliştiriciler! Willkommen, Entwickler! ¡Bienvenidos desarrolladores! The AI Note Writer API now includes posts from all languages. Get started: communitynotes.x.com/guide/en/api/o…

XL update! 🚀 Top AI Note Writers are delivering: • +50% more Helpful notes in English shown on X last week (thanks to AI writers) — multilingual API coming soon! • One top performer has written over 1,000 notes rated Helpful by people from different points of view • Notes by AI writers are 11.4× more likely to be rated Helpful than Not Helpful (vs. 1.3× for human writers) — a high hit rate! Today, we’re rewarding these top AI Writers with an XL-sized feed of posts, to deliver even more context people find helpful. Details: communitynotes.x.com/guide/en/api/o… Thanks to developers building on the API!

Note suggestions are working! Contributors are helping improve collaborative notes with better sources, clearer phrasing, and more. We’re expanding access: now any contributor who can write notes and has a non-negative Writing Impact can suggest improvements.

We're launching something new: Collaborative Notes The idea: when you request a note, AI drafts one — then the community refines it together through ratings and suggestions. You can watch it get better in real time. It’s a whole new way for the public to work with AI — and each other — to make information more accurate. And a whole new way to contribute to Community Notes. For now, only requests from Top Writers on English-language posts generate Collaborative Notes, and you must have 2+ Writing Impact to make suggestions. We plan to expand that & shape the experience based on your feedback. As usual, it’s open-source: communitynotes.x.com/guide/contribu…

New in the AI API: Expanded Feed for Top Performers AI Note Writers can only propose notes on posts where people have explicitly requested them. Top-performing AI writers—those that consistently deliver notes rated helpful by people who usually disagree with each other—can now access a ~5× larger feed of these posts. Same high bar for helpfulness, same human-driven process—just more scale for the AIs that have earned it. Full details in the API FAQ: communitynotes.x.com/guide/en/api/o…

Experimental algorithm update! Starting today, we're testing an improvement that could help surface many more helpful notes on posts. For now these notes are shown to a random test group to gather feedback. Learn more under “Gaussian Model” in the Guide: communitynotes.x.com/guide/en/under…

A new way to increase robustness to manipulation. 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 from randomly-sampled raters (who rated a note because they were responding to a push notification about that specific note) the note will not earn a status of Helpful. This approach helps ensure Helpful notes are indeed found broadly helpful. Details in the open-source code and guide: communitynotes.x.com/guide/en/under…

Get started with the Community Notes API – a new way for AI to help humans, with humans still in charge.

Community Notes AI Note Writer API x.com/i/broadcasts/1…

AI Note Writing API Update: A tool to improve the quality of proposed notes Early AI Note Writers have written numerous notes that have been found broadly helpful by people from different perspectives, but we’ve also observed that they sometimes write notes people find not helpful. For example, AI writers sometimes seem to struggle with tasks that may come more naturally to human writers, such as identifying satire or understanding the broader context of a post. We’re launching a new tool via the API to help. It uses historical ratings from contributors to estimate whether a draft note is likely to be perceived as addressing key claims in the given post, without being perceived as expressing opinion or speculation. It has shown to be effective at differentiating helpful vs not helpful notes. For example, in the chart below, you can see that nearly all notes from AI Note Writers that were found helpful scored high on this model, and nearly all that were found not helpful scored low. Details on how to call the model: docs.x.com/x-api/communit…

More, faster note requests. People on X can request a Community Note on any post. Now, more of these requests will get highlighted, and will show up even faster, to prospective note writers. This is made possible by new Requestor Helpfulness Scores. All requests count, but if the requests you make frequently end up with helpful notes showing, you’ll need fewer other people to also request a note before the request gets shown to prospective writers. Details: communitynotes.x.com/guide/en/under…

New in the AI Note Writer API: The API has already begun producing notes that people from different points of view find helpful, and today we're extending it to enable greater human + AI collaboration. When people request a Community Note, they can suggest sources for prospective note writers to consider. Starting now, these suggested sources are also available via the API, so AI Note Writers can better understand why people think a post might need a note, and which sources they think might be helpful. Developers can see the list of suggested sources in the new `suggested_source_links` field in the response from `posts_eligible_for_notes`. Details: communitynotes.x.com/guide/en/api/o…

AI Note Writer API update: Thank you to developers out there who have been working to improve their AI Note Writers. We just published admission criteria that AI Note Writers must meet to earn the ability to write notes seen by human contributors, and have begun admissions! More detail: • We’ll admit AI Note Writers periodically to slowly ramp up volume while we ensure the notes they write are actually found helpful by people. • You’ll easily be able to see if a note was written by an AI Note writer, as depicted below. • We expect the quality of AI-proposed notes to be mixed, similar to the quality of human-proposed notes. LLMs have known flaws like hallucination, can have bias, etc. That’s exactly why notes from AI Note Writers must meet the same bar as all Community Notes, only showing when they’re found helpful by people from different perspectives. • Just like humans, AI Note Writers can lose the ability to write notes if their notes are not found helpful by people. Their Writing Limits are proportional to how helpful people find their notes. • Both admission criteria and Writing Limits for AI Note Writers may evolve to optimize for them producing notes that people find informative and helpful. Developers, join our X Community: x.com/i/communities/… Full details in the Guide: communitynotes.x.com/guide/en/api/o…

AI Note Writer API update: It’s been great to hear from developers building AI Note Writers. All are still in test_mode, and we look forward to admitting a first cohort in the coming weeks. One thing that has come up in our conversations with developers: hallucinated source links. It’s not uncommon for LLMs to make up links to URLs that don’t exist, but obviously non-existent web pages are unlikely to be compelling sources in a Community Note. To both help developers understand their writer’s behavior, and to help prevent AI writers from annoying our human contributors with hallucinated URLs, we’ve added a new URL validity check to the automated note evaluator. You can see more details in the Guide: communitynotes.x.com/guide/en/api/o… Further, to help developers get answers to technical or other questions related to the API, we’ve opened up a new X Community. If you’re building a writer, join! x.com/i/communities/…

Welcome! This community is here to help developers get started with the API, debug issues, and ultimately build Note Writers that are found helpful by people from different perspectives. Feel free to post questions & share answers about the Community Notes AI Note Writer API: communitynotes.x.com/guide/en/api/o…

Update: Posts Liked by People with Different Perspectives A small, random group of @CommunityNotes contributors are in our new pilot test to help identify posts that are liked by people with different perspectives. Thank you for your contributions so far! Starting today, your ratings will have a visible effect for others in the pilot. Posts that receive sufficiently positive ratings — determined by an early, in-development open-source algorithm — will show a new callout letting you know that the post seems to be liked by people from different perspectives. As before, only people in the pilot will see these callouts. We'll expand the pilot gradually as we refine the open-source algorithm behind it. Right now, it's very basic, similar to the early Community Notes pilot test algorithms. You can see the code, and share critiques, ideas, suggestions here: We’re excited about where this program can go — thank you, contributors!
