Alphabet's YouTube has introduced a feature called Community Notes to provide additional information and context in videos.

The feature aims to combat misinformation and clarify elements like parodies and old footage, particularly during the US election year.

Selected users will write notes that are evaluated for accuracy and usefulness by third-party reviewers before being published.

YouTube will use an algorithm to determine which notes to publish based on viewer evaluations, with potential global expansion if successful.

Concerns remain about YouTube's ability to ensure impartiality, given Google's past errors and bias.

The feature is currently limited to eligible US contributors and available on mobile for English videos.
