Grok AI Personalizes X Feed with Custom Topic Selection

X to let Grok personalize timelines based on selected topics for each user

Updated: 3 min read

X is replacing its last real social feature with a bot that watches you. The company announced it will let its Grok AI build personal timelines based on topics users select. Android users get it first, very soon.

The trade is blunt: they're also killing X Communities on May 6th. The official reason is declining usage. The unofficial reason is that a single-user AI feed is cheaper to run than a multi-user forum.

Grok will personalize your timeline based on the topics you select. "It's powered by Grok's understanding of every post with the algorithm's personalization -- meaning every timeline is made just for you," Bier writes. "And it works even better when it's a topic you already engage with." Bier says early access to the Grok-powered timeline is coming to Android users "very soon." Along with this update, Bier also announced that X is deprecating X Communities -- formerly Communities -- due to "declining usage" on May 6th. X Communities allowed users to connect with others through feeds dedicated to specific topics.

This is the logical endpoint for a platform that long ago stopped pretending to be about public conversation. Communities were clunky and required other people. Grok is clean and requires only your data.

The promise is a feed perfectly tailored to your stated interests. The product is a more efficient way to keep you scrolling, alone. It might even be engaging.

But it turns a square into a very well-designed hallway.

Common Questions Answered

How will Grok personalize X users' timelines based on selected topics?

Grok will use its large language model to scan and match posts to users' selected topics of interest. The AI-powered algorithm will curate a personalized feed by understanding the content of each post and aligning it with the user's chosen topics, potentially improving content relevance.

When and for which users will the Grok-powered personalized timeline be available?

Early access to the Grok-powered timeline will be coming to Android users 'very soon', according to X. Currently, premium iOS users can already try the feature, with broader rollout expected in the near future.

What makes the Grok-powered timeline different from X's previous content curation approach?

Unlike previous broad engagement signals, the new feature gives individual users more control over their feed by allowing them to select specific topics of interest. Grok will then use its advanced language understanding to match posts more precisely to these chosen topics, creating a more personalized experience.
