X Launches Grok-Powered Custom Timelines for Premium Users

The AI-tuned streams serve as a test bed for a more personalized, subscriber-led feed.

Overview

  • X, which began rolling out early access Wednesday, is letting Premium subscribers on iOS pin topic-specific feeds to the Home tab.
  • The new feeds cover more than 75 topics and use Grok to adapt recommendations based on each person’s interactions.
  • A Snooze Topics toggle now lets Premium members mute subjects in the For You feed on iOS and the web.
  • Android support is listed as coming soon as X staggers the release to measure performance and user uptake.
  • The move shifts X from a single algorithmic feed toward user-configured streams that can help niche communities like crypto track real-time updates with less noise.
