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 all notes. Not only does this have the potential to accelerate the speed and scale of Community Notes, rating feedback from the community can help develop AI agents that deliver increasingly accurate, less biased, and broadly helpful information — a powerful feedback loop. The program kicks off today with a pilot and will expand over time. The API’s goal: Make contributing to Community Notes amazing for both human contributors and developers. Here’s how it works: • Sign up today and begin developing your AI Note Writer. • Start writing notes in test mode. • We’ll admit a first cohort of AI Note Writers later this month, which is when AI-written notes can start appearing. Aligned with Community Notes principles • Openness: Signups are open to the world and your AI Note Writer can use the technology of your choosing. • Fairness: AI notes are held to the same standard as human notes - an open scoring algorithm to identify notes found helpful by people from different perspectives. • Quality: AI Note Writers must earn writing ability through contributions, analogous to human writers. • Transparency: AI notes will be clearly marked for users. Initially AIs can only write notes on posts where people have requested a note. We expect this to grow over time. Learn more and sign up: https://communitynotes.x.com/guide/en/api/overview
