Nikita Bier, X’s head of product, has announced the launch of custom timelines, which lets you curate what you see on your feed based on your topics of interest. He called the update “one of the biggest changes to X” and a ”huge undertaking” that took the team “many months” to develop. The feature lets you pin specific topics to your home tab, so you can switch from one to the other to see the latest discussions about your interests and hobbies.

Bier said that X’s custom timelines is “powered by Grok’s understanding of every post with the algorithm’s personalization.” You have 75 topics to choose from, including food, art, photography, business, finance, movies and TV. As you’d expect, the personalization aspect of the feature works better if it’s a topic you already engage with regularly. X’s new feature is similar to Bluesky’s and Threads’ custom feeds, which also allow you to pin topic-based timelines to the home screens of the apps, and which their users have been enjoying since 2023 and 2024, respectively.

At the moment, X’s custom timelines is still in its early access phase and is only available to Premium subscribers on iOS. It will be rolling out to Premium users on Android “very soon,” as well. Bier has also announced that X has released a tool to snooze topics on the For You tab. With the tool, you’ll be able to hide certain topics, such as politics or sports, for 24 hours from your feed. It’s now available for Premium users on iOS and the web.
