What is the Twitter Birdwatch feature used for?

Twitter Birdwatch was a pilot program launched by Twitter in January 2021 aimed at addressing misinformation on the platform. Birdwatch allowed users to annotate tweets with notes providing context or additional information to help users better understand the content and assess its credibility. These annotations were visible to other users and could be upvoted or downvoted based on their helpfulness.

The Birdwatch feature was designed to empower the Twitter community to contribute to the contextualization of tweets and combat misinformation by crowdsourcing fact-checking efforts. However, it's important to note that Birdwatch was in the early stages of development and was only available to a limited number of users participating in the pilot program.

Since the information may have changed after my last update, I recommend checking Twitter's official announcements or news updates for the latest information on the status and availability of the Birdwatch feature.
