Continuing to evolve the fact-checking service that launched as Twitter’s Birdwatch, X has announced that Community Notes can now be requested to clarify problematic posts spreading on Elon Musk’s platform.

X’s Community Notes account confirmed late Thursday that, due to “popular demand,” X had launched a pilot test on the web-based version of the platform. The test is active now and the same functionality will be “coming soon” to Android and iOS, the Community Notes account said.

Through the current web-based pilot, if you’re an eligible user, you can click on the “•••” menu on any X post on the web and request fact-checking from one of Community Notes’ top contributors, X explained. If X receives five or more requests within 24 hours of the post going live, a Community Note will be added.

Only X users with verified phone numbers will be eligible to request Community Notes, X said, and to start, users will be limited to five requests a day.

“The limit may increase if requests successfully result in helpful notes, or may decrease if requests are on posts that people don’t agree need a note,” X’s website said. “This helps prevent spam and keep note writers focused on posts that could use helpful notes.”

Once X receives five or more requests for a Community Note within a single day, top contributors with diverse views will be alerted to respond. On X, top contributors are constantly changing, as their notes are voted as either helpful or not. If at least 4 percent of their notes are rated “helpful,” X explained on its site, and the impact of their notes meets X standards, they can be eligible to receive alerts.

“A contributor’s Top Writer status can always change as their notes are rated by others,” X’s website said.
