YouTube is currently testing a new feature called notes that allows viewers to add community-sourced context to videos. This feature will enable people to clarify if a video is a parody or if it contains older footage presented as current events. Notes rated as helpful will appear in a small box beneath the video, providing valuable information to viewers. YouTube is currently selecting a limited number of eligible contributors to write notes, with third-party evaluators rating their helpfulness. The platform will use this feedback to improve its note evaluation system over time. As the pilot progresses, YouTube will ask viewers to rate notes as helpful, somewhat helpful, or unhelpful, which will improve the algorithm's ability to display notes deemed broadly helpful. Currently only available in English to mobile users in the US, notes could potentially introduce errors or unrelated information due to increased participation. Other platforms like Twitter have also started testing similar community note features to provide context to posts.
