X is shutting down Communities on May 30 and replacing them with Grok-powered Custom Timelines—personalized topic feeds you can pin directly to your home tab. The new feature lets Premium iOS users choose from over 75 topics, ranging from Formula 1 and K-pop to cryptocurrency and biotech.
Unlike keyword-based filtering, Grok actually reads and labels every post before deciding where it belongs. The result is a feed that gets sharper the more you already engage with a topic.Head of product Nikita Bier called it “one of the biggest changes to X”—a claim that’s hard to dispute given how static the home tab has been for years.
Custom feeds aren’t new—Bluesky and Threads have had them since 2023 and 2024
X is clearly catching up here, but there’s a practical upside to the late arrival: Grok’s real-time post analysis goes deeper than what competitors currently offer.
You can pin up to 10 topics, reorder them however you like, and toggle between feeds from the home tab. A new Snooze Topics tool also lets you mute categories like politics or sports for 24 hours—useful during, say, a slow news cycle or a particularly exhausting news week.The Communities shutdown didn’t go down smoothly at first. Creators pushed back hard on losing public forums, prompting X to extend the migration deadline from May 6 to May 30 and bump group chat limits from 350 to a planned 1,000 members.
Every second slot in the custom feeds is an ad—X quietly expanded its ad inventory with this launch
Android support is coming soon. The Snooze Topics tool is already live for Premium subscribers on iOS and web. Whether the custom timelines can fill the social void left by Communities is the bigger open question—group chats and curated feeds serve pretty different needs, and not everyone’s convinced the trade-off is worth it.
