X Rolls Out AI-Powered Custom Timelines for Premium Users

Wednesday April 22, 2026 2:49 am PDT by Tim Hardwick

X, formerly Twitter, has announced it is launching a custom timelines feature that allows users to pin specific topics to their home tab in the X app for iOS.

The company says custom timelines are powered by Grok AI, which understands the social media platform's algorithm personalization so that timelines are tuned for individual users.

Paying users will see an Add+ button appear next to the Following tab, with support for over 75 topics, ranging from design to robotics to real estate. X says Grok's filters work even better for topics a user already engages with.

Early access to custom timelines is currently limited to Premium subscribers on iOS, with Android set to follow "soon."

Ladies and gentlemen, today we're launching one of our biggest changes to Introducing Custom Timelines This feature allows you to pin a specific topic to your home tab.

Why is this being covered?

I don’t see what this has to do with Apple.

It’s not all about you. The platform has become far more useful for me and hundreds of millions of others as it now allows for real engagement and debate (ie, no silly censorship of ideas), and the community checks are fantastic as it stops misinformation from spreading far and wide as is happening too frequently on other social media platforms; combined with algos that reinforce bad ideas, creating self-righteous, mindless zombies who THINK they know it all.

Sigh...I don't use social media to debate, I use to interact with my friends and see what family is up to. Why does everyone want to promote controversy and argue?
