June 17 (Reuters) - Alphabet's YouTube will

soon allow users to add 'notes' that will provide context on

some of its videos as part of a new feature that will be

initially rolled out in the United States, it said on Monday.

YouTube will invite certain users and creators, as part of

the initial test phase, to write notes that are meant to provide

"relevant, timely, and easy-to-understand context" on videos.

The notes, for instance could clarify when a song is meant

to be a parody, point out when a new version of a product being

reviewed is available, or let viewers know when older footage is

mistakenly portrayed as a current event.

Social media platform X has a similar feature called

Community Notes through which it allows select contributors to

add context to posts including tags such as "misleading" and

"out of context".

The notes feature on YouTube will be available initially on

mobile to users in the U.S. and in English. In this phase,

third-party evaluators will rate the helpfulness of notes, which

will help train the systems, before a potential broader rollout,

YouTube said.

Viewers in the U.S. will start to see notes on videos in the

coming weeks and months.
