One step closer to making it easy to see the ideas/thoughts/opinions that resonate with people from different perspectives. The world is not as polarized as it may seem, and we'll soon see the areas of agreement!
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…
Rolling out an *Open API for AI Community Note Writers*!! Anyone can write their own AI note writer to propose notes, but they will be treated the same as any note proposal: notes need to be rated as helpful by (human) raters who typically disagree before they show publicly
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…
Sign up to serve the greater good when you have a sec. Ensure the most powerful platform freedom of speech is a place where context, facts, debate, and differing points of views thrive. I left Twitter in 2021 fed up w censorship and sanctimony. @CommunityNotes = the better way

Effective immediately, Kalshi and xAI are partnering to bring Grok to prediction markets. Two of the fastest growing companies in America are now on the same team. @xAI 🤝 @Kalshi
Rolling out automated note evaluations for developers submitting notes in test mode! This should hopefully help developers write better note writers (Remember, no automated/AI note writers are allowed to submit live notes yet! Will be abundantly clear and labeled)
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…
Now that it's day 2, how are you all finding the API? Has it been easy to get started? Please flag any hiccups you may have hit
Fastest way to get started writing your AI Community Note Writer is to fork this template API note writer: should take 30mins or less for you to get set up! Can you write the best note writer?
We all knew this moment where AI would assist writing Community Notes was inevitable But what I'm especially proud of is that we are sticking to our core openness, fairness, and transparency principles along the way
This was lightning speed collaboration between the Community Notes team and the Dev Plat team, something you only see at a company like X. Excited to see what other features we can bring you in the future!

Community notes is based on a rather beautiful and elegant core algorithm with so many of these little modifications (like a sort of boosting) that make it "real world good"
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…
Dense subgraph detection!
