Social media giantXhas officially overhauled its user experience with the launch of 'Custom Timelines,' aGrok-powered update described by head of product Nikita Bier as 'one of our biggest changes' to the platform.
The feature, which rolled out globally on Wednesday, 22 April 2026, allows users to bin the 'one-size-fits-all' algorithm in favour of highly specialised niche feeds. By enabling users to pin over 75 distinct topics directly to their home screen, the update effectively decentralises the traditional 'For You' tab into a series of personalised information hubs.
At its core, 'Custom Timelines' represent a fundamental shift in how content is distributed on the platform. Rather than relying on a singular, opaque algorithm to predict what a user might enjoy, the new system allows for the creation of dedicated spaces for specific interests.

The technology is driven by X's proprietary AI, Grok, which parses every post in real-time to categorise content with high precision. This feature converts broad topics into algorithmic feeds focused on a single subject, a move specifically designed to reduce the 'noise' often associated with the general timeline as reported byNewsNine.
'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 works even better when it's a topic you already engage with,' Brier said.
Moreover, the user's timeline is further personalised by Grok through algorithms based on the user's past behaviour or historical engagements. This level of customisation is part of a broader push to transform X into an'everything app'that functions as a primary source for specialised news and community interaction.
Bier, described the launch as a major milestone for the platform. 'This feature allows you to pin a specific topic to your home tab,' Bier stated during the announcement. 'With support for over 75 topics, you can dive deep into your favourite niche on X.'
For users looking to build their perfect feed, the process is straightforward, though it currently requires an X Premium subscription. To start, users must navigate to the 'Topics' menu, where they can browse a library of over 75 interest categories. Once a topic is selected, a 'Pin to Home' option appears, creating a new tab alongside the standard 'Following' and 'For You' feeds.
The system also introduces a more granular level of control through a new'Snooze' tool. This allows users to temporarily or permanently suppress topics within their 'For You' tab if the content becomes repetitive or irrelevant. Bier noted that this tool is essential for those who want to 'crank up or turn down the slop' in their daily digital diet.
