Grok powers the new feed, in early access for Premium subscribers on iOS with Android to follow.

[Grok](<https://creatorstoolbox.com/tools/grok>) now powers a personalisation feature on X called Custom Timelines, which lets users pin a specific topic to their home tab. There are more than **75** topics to choose from, and X says Grok's understanding of every post combines with the existing algorithm to build a timeline tailored to each user.

The feature is in [early access](<https://x.com/i/status/2046736181002645520>) for Premium subscribers on iOS, with Android support coming soon.
