Comment topics use artificial intelligence (AI) to organise and summarise comments on YouTube videos. This feature can help you discover themes in comment sections and join the discussion without having to read every comment.
To get started, open the comments section of a video on the YouTube Mobile app. If available, tap Topics 
Topics are summarised by AI and not humans, so quality and accuracy may vary. Comment topics are available in all languages supported by YouTube comments.
