Grok brings personalized timelines to X
X's new AI-powered custom feeds, curated by Grok, mark a major product shift: Communities are being phased out in favor of dynamic, topic-focused timelines that adapt to user interests. Instead of manual community membership, users can follow or create custom feeds that the AI populates with relevant posts, replies, and media based on signals like interests, engagement patterns, and topical relevance.
The immediate benefit is clearer discovery. By surfacing higher-relevance content, custom feeds help users find conversations and creators they care about without wading through unrelated noise. For niche topics and fast-moving events, Grok's curation can bring together the best posts across the platform, improving signal-to-noise for everyone.
Creators and advertisers gain new opportunities. X is introducing new ad slots tied to these AI feeds, which means more targeted, contextually relevant ad placements and fresh revenue opportunities for creators whose content aligns with specific feeds. Advertisers can reach audiences around clear topical buckets, while creators can reach engaged, interest-driven viewers.
Overall, the shift from Communities to Grok-powered custom feeds positions X to be more personalized, discoverable, and commercially sustainable. If the rollout continues to prioritize transparency and user control over AI curation, these feeds could meaningfully improve everyday experience on the platform while opening up new paths for creators and advertisers.
