• New system organizes content by interest with automatic sorting
• Users can follow multiple topics with pinned and flexible navigation

X has announced a new feature that enables the creation of AI-powered custom feeds, built on the Grok model, aimed at delivering organized content based on user interests across more than 75 categories.

The feature allows users to view topic-based feeds that can be pinned to the home page and tailored according to user behavior and preferences. It relies on a comprehensive analysis of posted content, automatically classifying it rather than depending on keywords or traditional hashtags.

The feature is currently available to paid subscribers on iOS devices, with a planned rollout to Android, and access extended to all premium subscription tiers.

Available categories cover a wide range of areas, including news, sports, technology, economy, and entertainment, alongside detailed subcategories such as football, basketball, motorsports, tennis, and wrestling, as well as cultural topics like music, fashion, and podcasts.

Additional categories include specialized tech fields such as artificial intelligence, cryptocurrencies, robotics, and space, along with general interests like mental health, design, pets, and shopping.

The move comes alongside the discontinuation of the “Communities” feature, which previously allowed users to form discussion groups around specific topics but saw declining usage.

According to the platform, these timelines are generated through the Grok system, which analyzes posts, understands their content, and categorizes them automatically, reflecting a deeper integration between AI systems and the platform’s services.

The feature allows users to pin up to 10 timelines or lists on the home page, with the ability to reorder and navigate between them easily, aiming to enhance personalization and improve the browsing experience.
