X launches Grok-powered custom timelines with 75+ topics
X has introduced Grok-powered Custom Timelines, allowing Premium subscribers on iOS to pin curated feeds on over 75 topics to their home tab. The feature uses xAI's Grok AI to read every post, assign topic labels, and personalize feeds. Topics range from broad categories like Business & Finance, Sports, Technology, and Politics to niche interests such as K-pop, Formula 1, digital art, and mental health. News categories prominently feature Iran conflict, crime, and elections. The second position in each feed is an ad, potentially boosting ad inventory. X is also shutting down X Communities due to declining use, while rolling out joinable links for XChat groupchats and a Snooze Topics tool for the For You tab. The custom timelines are available only on iOS for Premium subscribers, with Android support in development.
