On April 22, X announced the launch of its 'Custom Timelines' feature, aimed at enhancing user engagement by allowing specific topics to be pinned on the homepage tab. According to BlockBeats, this new feature supports over 75 interest topics, enabling users to explore niche content areas more deeply.
The feature is powered by Grok's content understanding and platform algorithms, offering personalized recommendations that dynamically generate timelines based on user interests. This is particularly effective for topics where users already have interaction preferences. Currently, early access to this feature is available for Premium subscribers on the iOS platform, with an Android version expected to be released soon.
