WED, APR 22, 2026

X has unveiled Custom Timelines, a new feature allowing Premium subscribers to pin specific topics directly to their home tab. The feature, powered by Grok AI, is now in early access on iOS with support for over 75 topics.

Custom Timelines enables users to curate their X experience by selecting niche topics of interest and displaying them as dedicated tabs. The feature leverages Grok, X's AI assistant, to organize and surface content within chosen categories. The rollout begins with Premium subscribers on iOS, positioning the feature as an exclusive benefit for paid users. With over 75 topic options available, users can customize their feed across diverse categories. This update represents one of X's most significant interface changes since Elon Musk's takeover. The feature addresses longstanding user requests for better content filtering and personalization, allowing subscribers to focus on specific communities or subjects rather than relying solely on algorithmic recommendations. Expansion to Android and broader user access has not been announced. The early access phase will likely inform future iterations and rollout timelines.
