YouTube is trialling two new features to improve user engagement and content creation. One enhances comment readability, while the other helps creators produce music using AI for Shorts.

A new threaded layout is being tested to organise comment replies under the original post, allowing more explicit and focused conversations. Currently, this feature is limited to a small group of Premium users on mobile.

YouTube also expands Dream Track, an AI-powered tool that creates 30-second music clips from simple text prompts. Creators can generate sounds matching moods like 'chill piano melody' or 'energetic pop beat', with the option to include AI-generated vocals styled after popular artists.

Both features are available only in the US during the testing phase, with no set date for international release. YouTube's gradual updates reflect a shift toward more intuitive user experiences and creative flexibility on the platform.
