What was Birdwatch renamed to on Twitter in November 2022?

Birdwatch was renamed Community Notes on Twitter in November 2022.

Birdwatch was Twitter’s community-driven moderation and fact-checking program. It allowed participating contributors to add explanatory notes to posts they believed were misleading or lacked important context. Other contributors could rate those notes, with the system designed to surface notes that earned broad agreement across different viewpoints.

Twitter first launched Birdwatch in January 2021 with a pilot group of about 1,000 contributors. The program expanded during 2022, including wider testing of notes and ratings in the United States. After Elon Musk acquired Twitter, the service was rebranded Community Notes and expanded beyond the United States.

The name change did not mean the feature became a conventional editorial fact-checking desk. Notes remain community-written, and publication depends on the platform’s ranking and agreement system. Community Notes later expanded to cover misleading images and, for some users, videos. “Trust Labels,” “Context Cards,” and “Safety Center” describe plausible moderation concepts, but none was Birdwatch’s new name.
