If you’ve spent any time on X/Twitter lately, you may have noticed little context bubbles popping up under tweets—these are Community Notes, the crowd‑sourced fact checks that live alongside posts. Now, X is taking a bold step to supercharge the program: it’s inviting AI developers to build “AI Note Writers” that can draft these notes, too.

Just like human contributors, AI Note Writers will propose context for posts that users flag as needing clarification. But unlike humans, these bots will operate behind the scenes until they’ve proven their value. X says notes from AI will be “clearly marked for users,” and—at least to start—AI bots can only chime in on posts where someone has explicitly requested additional context.

Developers around the globe can submit their custom AI agents through X’s new Note Writer API. Once registered, each bot enters a “test mode,” where it drafts practice notes behind the scenes. If those drafts earn high marks from X’s human raters, the bot will “earn the ability to write notes” that could actually appear under posts in the wild. According to X’s developer guide, bots can “gain and lose capabilities over time based on how helpful their notes are to people from different perspectives,” ensuring only the most reliable agents stay active.

Despite the AI infusion, X emphasizes that humans remain in the driver’s seat. The platform will only display AI‑generated notes if real people from diverse viewpoints agree they’re helpful—a safeguard straight out of the existing Community Notes framework. As Keith Coleman, X’s VP of product and head of Community Notes, told Bloomberg:

They can help deliver a lot more notes faster with less work, but ultimately the decision on what’s helpful enough to show still comes down to humans. So we think that combination is incredibly powerful.

The pilot kicked off on July 1, when X opened the doors for the first cohort of AI Note Writers. While the company hasn’t disclosed exactly how many bots it will admit initially, Coleman hinted to Bloomberg that “hundreds” of human‑written notes already go live daily—so even a small AI cohort could represent a significant boost. As the bots’ notes undergo community review, X will continuously adjust each agent’s permissions, ensuring low‑quality writers get sidelined and top performers get more visibility.

Community Notes has become one of X’s flagship trust‑and‑safety features, offering user‑driven fact checks on everything from breaking news to viral rumors. But scaling a fully human program is labor‑intensive, and the demand for timely context often outpaces supply. By harnessing AI, X hopes to:

• Expand reach: More eyes on more posts means covering a wider array of topics.
• Increase speed: Bots can draft notes in seconds, accelerating the fact‑checking pipeline.
• Maintain quality: The same crowd‑sourced rating system applies, so only the most helpful notes surface.

For now, AI Note Writers remain in “test mode,” but if their early drafts impress both human raters and the broader community, you’ll soon see bot‑crafted context peeking out from beneath your favorite posts. After all, in X’s own words: “AI helping humans. Humans still in charge.”
