X Launches Grok-Powered Custom Timelines With Over 75 Topic Feeds for Premium Users

X has launched “Grok-powered Custom Timelines,” a feature that lets users pin curated topic feeds to their home tab, and the company is positioning it as “one of the biggest changes” to the app to date.

TechCrunch reports that the feature lets people “dive into one of over 75 specific topics through curated feeds,” and that X says it uses Grok’s AI both to build these timelines and to personalize them for individual users.

The update arrives as X announces it is shutting down X Communities, a feature that “had allowed people to create their own member-based communities around various topics, but saw declining use,” according to TechCrunch.

Business Standard similarly says X has introduced Custom Timelines so users can pin specific topics directly to their home feed, with Grok curating posts based on selected interests and activity and activity.

Engadget frames the change as a shift in what users see, saying Nikita Bier called it “one of the biggest changes to X” and a “huge undertaking” that took the team “many months” to develop.

In the announcement coverage, multiple outlets tie the feature directly to Grok’s understanding of posts and X’s personalization, with TechCrunch saying Grok “reads every post, understands it, and then adds topic labels.”

Across the coverage, X’s Custom Timelines are described as topic-pinning controls that replace or supplement the default “For You” and “Following” feeds with dedicated streams.

TechCrunch says users scroll to the right past “For You” and “Following,” then tap the plus ( + ) sign to choose which custom timelines to pin to their home tab, and it adds a constraint: “you can only pin up to 10 topics or lists!”

It also describes how the feed is constructed: X says the timelines “aren’t based on traditional signals like keywords or hashtags,” and instead Grok “reads every post, understands it, and then adds topic labels.”

Business Standard says the feature supports “more than 75 topics,” and it describes the experience as switching from a general feed to a timeline dedicated to a single topic, where posts are “filtered and prioritised based on the selected interest.”

Engadget adds that the feature is “powered by Grok's understanding of every post with the algorithm's personalization,” and it lists example categories including food, art, photography, business, finance, movies and TV.

TechCrunch provides a longer catalog of initial topics, including “Business & Finance,” “Sports,” “Technology,” “Politics,” “Stocks & Economy,” “News,” “Science,” and “Movies & TV,” plus sub-sports such as “American football” and “Formula 1.”

Alongside Custom Timelines, X is rolling out controls that let users temporarily tune out topics on the main feed.

Engadget says Bier announced that X “has released a tool to snooze topics on the For You tab,” and it specifies that users can “hide certain topics, such as politics or sports, for 24 hours from your feed.”

Engadget also says the snooze tool is “now available for Premium users on iOS and the web,” and it frames the tool as a way to avoid certain content without permanently blocking accounts or muting words.

TechCrunch similarly describes the custom timelines interface as a set of pinned topic streams that appear on the home tab across platforms, and it notes that the second position in each feed was filled by an ad.

Android Headlines adds that X rolled out a new tool that allows users to “snooze topics on their ‘For you’ tab,” and it describes the feature as improving control over content.

International Business Times UK reports that the feature “rolled out globally on Wednesday, 22 April 2026,” and it describes the system as introducing a “Snooze” tool that can “temporarily or permanently suppress topics within their ‘For You’ tab.”

The rollout coverage repeatedly centers on statements from X’s product leadership, especially Nikita Bier, who is quoted describing the project and its intent.

TechCrunch says that on X, the company’s head of product, Nikita Bier, noted that the custom timelines work “even better for topics you already engage with.”

Business Standard quotes Bier directly, saying, “This was a huge undertaking across many months, so we're excited for you to take it for a spin.”

Engadget similarly reports Bier’s characterization of the update as “one of the biggest changes to X” and a “huge undertaking” that took the team “many months” to develop.

MacRumors also ties the feature to Bier’s announcement, quoting the tweet text that begins “Ladies and gentlemen, today we're launching one of our biggest changes to 𝕏 Introducing Custom Timelines.”

Android Headlines includes a longer quote from Bier’s post, stating, “It’s powered by Grok’s understanding of every post with the algorithm’s personalization—meaning every timeline is made just for you,” and it adds Bier’s line that “it works even better when it’s a topic you already engage with.”

While the core description of Custom Timelines is consistent, the outlets emphasize different aspects of what the feature changes and how it should be interpreted.

“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”

TechCrunch frames the launch as a major app change and highlights both the mechanics and the potential ad implications, noting that “the second position in each feed was filled by an ad — which suggests X just found a way to increase its ad inventory.”

It also describes a news-related set of topics that “leads with the Iran conflict, crime, and elections at the top of suggestions,” and it explicitly connects product decisions to what news people see.

Business Standard focuses on the user-control promise and says the feature “gives users more control over what they see on the platform by focusing on topics they care about,” while also describing it as a shift from “a single mixed timeline” to “more personalised and topic-based feeds.”

Engadget compares the feature to other platforms’ topic-based feeds, saying it is “similar to Bluesky’s and Threads’ custom feeds,” and it places emphasis on the pin-and-switch experience across topics.

International Business Times UK emphasizes the structural change, describing Custom Timelines as “a fundamental shift” that “decentralises the traditional ‘For You’ tab into a series of personalised information hubs.”

The reporting across outlets indicates that Custom Timelines are in early access and that X plans staged expansion, with Android and broader availability described as upcoming.

TechCrunch says that at launch the custom timelines are available only to Premium subscribers on iOS and that “Android support is in the works,” while also stating that “All Premium subscription tiers can access this feature.”

Business Standard similarly says it is “currently rolling out in early access to Premium subscribers on iOS, with Android support expected soon,” and it adds that the update marks a shift toward “more personalised and topic-based feeds rather than a single mixed timeline.”

Engadget says the feature is “still in its early access phase and is only available to Premium subscribers on iOS,” and it adds that it will be rolling out to Premium users on Android “very soon.”

International Business Times UK reports that Android and Web versions are “in the final stages of testing,” and it notes that there are “no official announcements” if Custom Timelines will be rolled out to free users.

The Eastleigh Voice’s local write-up says the feature is being rolled out in phases and that “Some users may see it earlier than others depending on their device, region, or whether they are part of a test group.”
