The feature is powered by Grok, which parses every post to ensure only high relevance content makes it into the niche feed.
More than 75 topics are available at launch, including Cryptocurrency, AI, Stocks, and Gaming.
Currently available for Premium subscribers on iOS, with Android and Web versions coming soon.

Tailoring digital newsrooms has never been easier now that X debuted Custom Timelines, a Grok tool that allows Premium users to pin 75+ specific topics to their Home tab for a noise free browsing experience.
From Follower Graph to Interest Graph
For years, X was built on who you follow (the social graph). With the launch of Custom Timelines, the platform is moving toward what you love (the interest graph). According to Nikita Bier (Head of Product at X), this feature lets you dive deep into specialized areas without being distracted by the general chaos of your main feed. For a trader or researcher, this means you can have a dedicated tab that updates in real time, filtered by Grok’s advanced understanding of the market. This focus on data is a win for productivity.

Navigating Your Niche with Grok
Unlike the old Lists functions, which requires you to manually add accounts, Custom Timelines are algorithmic. When you pin a topic like Artificial Intelligence or Formula 1, Grok scans the entire platform to find the most relevant and high quality posts, even from accounts you don’t follow. This ensures you never miss a trending development in your field.

For content creators and professional researchers, this is a game changer. It means your content is more likely to be seen by people who care about your specific niche rather than being buried under general news.
However, this will raise the bar for quality. Since Grok is the gatekeeper, your posts need to be high signal and relevant to stay in these custom feeds. In a world full of digital noise, the most valuable tools are the ones that help us focus on what matters to our work and our wealth.
