Social media giant X has officially overhauled its user experience with the launch of 'Custom Timelines,' a Grok-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.
