To help creators engage more easily with their audiences through comments, YouTube is testing new AI-enhanced comment reply suggestions. This feature allows creators to edit suggestions to fit their own tone and style for better interaction with viewers. Users will soon start seeing comment reply suggestions in the 'Comments' or 'Community' tab in Studio and the YouTube mobile app. Additionally, the comment reply suggestions are completely optional and editable; if you do want to edit a suggestion, simply do so before posting your comment.
