X has rolled out custom timelines, a feature that lets users tailor their home feed around specific interests rather than relying solely on the platform’s default algorithm. Announced by Nikita Bier, X’s head of product, the update allows subscribers to pin chosen topics directly to their main tab, making it easier to jump between curated views of discussions on everything from food and photography to business, finance, or movies and television.
The system draws on Grok’s analysis of posts combined with X’s existing personalization tools. In practice, this means recommendations tend to improve for topics users already interact with regularly. There are currently 75 topics available to select from, though the list feels somewhat conventional rather than exhaustive. Early testing suggests the feature works as advertised for active users, but its effectiveness will likely vary depending on how well the underlying models interpret niche or fast-moving conversations.
This is not entirely new territory. Bluesky introduced similar custom feeds back in 2023, followed by Threads in 2024, and both have seen steady adoption among users seeking more control over their experience. X’s version arrives later, framed internally as a significant technical effort that required months of development. Whether it delivers a meaningfully different experience remains to be seen once it moves beyond early access.
For now, custom timelines are limited to Premium subscribers on iOS, with an Android rollout described as imminent. Alongside the main feature, X has also added a topic snooze option for the For You tab, letting users temporarily hide subjects such as politics or sports for 24 hours. That tool is already live for Premium users on iOS and the web.
The move reflects a broader pattern across social platforms: after years of pushing algorithmic “For You” feeds as the default, companies are gradually giving users more granular ways to opt out or refine what they see. It is a quiet acknowledgment that not everyone wants an endless stream shaped purely by engagement metrics. Custom timelines could help reduce the fatigue that comes from over-personalized or off-topic content, though success will depend on how reliably the system surfaces relevant posts without simply amplifying the loudest voices in each category.
At this stage, the feature feels like a sensible but incremental improvement rather than a fundamental shift in how people use X. Its real test will come as more users experiment with it and as the platform expands availability beyond iOS Premium subscribers. If it encourages people to spend time in topic-specific lanes instead of doomscrolling the main feed, it may quietly improve daily experience on the app. If it simply adds another layer of complexity without clearer value, it risks blending into the background like many other half-finished tweaks social platforms have tried over the years.
