Community Notes (formerly Birdwatch) is Twitter/X's crowd-sourced fact-checking feature that allows contributors to add context to potentially misleading tweets. When a note is rated helpful by enough contributors from different perspectives, it appears directly on the tweet for all users to see. The system aims to provide additional context to help users make more informed decisions about the content they encounter. Community Notes operates on a bridging-based rating system that prioritizes notes found helpful by people with diverse viewpoints, attempting to reduce partisan bias in the fact-checking process.
