YouTube said in the announcement that it is aiming to “reduce friction” when users attempt to learn more about a subject. As a commenter, you have no power to pick which word is hyperlinked or remove a hyperlink. However, the company said creators can remove those hyperlinks from their video’s comments if they want.

YouTube launches hyperlinked comments for topic exploration, causing mixed reactions over potential spam and learning enhancement.

YouTube's new hyperlinked comments add functionality by offering users more context on specific topics. The feature has begun rolling out on Android and iOS, but appears to lack consistency. Hyperlinked keywords will appear in blue with a magnifying glass icon next to them.
