YouTube has introduced a new feature called "Previews" for its mobile app, which allows users to view sneak peeks of recommended videos. This feature is currently being tested with a select group of users and presents "five to 10" previews through an entry card on the homepage. Users can choose to watch the full video or save it for later after viewing the previews. Additionally, YouTube has launched the "Reimagine" feature for Shorts, enabling users to transform scenes from a Short using AI. More AI-driven features are planned for development by 2026.
