Hands on with X’s new AI-powered custom feeds

X has launched Grok-powered Custom Timelines, allowing users to dive into specific topics through curated feeds that can be pinned to their home tab. The feature uses AI to build and personalize custom timelines for individual users, and is available to Premium subscribers on iOS, with Android support in the works. Custom timelines work better for topics users already engage with, and can be accessed by scrolling past personal lists on the app.
