Twitter begins rolling out 'Community Notes' feature to users worldwide

"Contributors can suggest a note on any Tweet. Notes are then rated for helpfulness by other contributors. Notes are only shown on Tweets if they are rated helpful by enough people from different perspectives. The more people that participate, the better the program becomes."

As per Community Notes Guide, Contributors are people on Twitter,  who chose to enrol to write and rate notes.

The company also added that the rollout is still in process and will add contributors from a first new country soon.

Twitter chief Elon Musk said that "it will have a powerful impact on falsehoods".

"Community Notes works differently than the rest of Twitter. It is not a popularity contest. It aims to find notes that many people from different points of view will find helpful. It takes into account not only how many ratings a note has received, but also whether people who rated it helpful seem to come from different perspectives. Because notes need to genuinely be found helpful by people who tend to disagree, the program is more likely to identify notes that many people find helpful," the guide added.
