Elon Musk-owned X is bringing its AI chatbot Grok to the centre of how users see content on the platform, with a new timeline customisation feature for Premium users.

In an announcement, X product head Nikita Bier said iOS Premium subscribers will get early access to a tool that lets them pin specific topics (over 75) to their home tab. Grok will then use those topics to curate posts across the timeline.

“It’s powered by Grok’s understanding of every post with the algorithm’s personalisation—meaning every timeline is made just for you. And it works even better when it’s a topic you already engage with,” Bier wrote.
“This was a huge undertaking across many months, so we’re excited for you to take it for a spin,” he added. The feature will be rolled out to Android users “very soon.”

Alongside this, X is moving away from its Communities feature, which allowed users to interact in topic-based groups. The company had earlier set a two-week window for users to migrate, but that deadline has now been extended.

“We’ve heard you. To give sufficient time to migrate: You’ll have until May 30th to transition to XChat,” Bier said. He also added that group chat limits will be increased to support larger communities.

X is now encouraging users to shift to group chats via its messaging service, XChat, where public joinable links can be shared and pinned to bring members together. The move comes as the platform cited “declining usage” for Communities.

At the same time, the company is rolling out a new “Snooze” feature. This will allow users to temporarily mute topics on their “For You” feed.

“Today we’re also rolling out a tool to snooze topics on your For You tab—if you ever want to crank up or turn down the slop,” Bier said. The feature is currently available for Premium users on iOS and web.

The developments come at a time when Musk is facing scrutiny in France over Grok’s functioning. According to The Independent, prosecutors in Paris had summoned Musk as part of an ongoing investigation led by the cybercrime division, which is examining allegations related to algorithm misuse and unlawful data extraction.

The probe was first opened in January 2025 following complaints over concerns of bias in the system. It has since widened with investigators later adding more serious angles after new evidence emerged. These include concerns around explicit AI-generated content and the use of images without consent.
