X is shutting down Communities and replacing them with two things it clearly thinks are more useful: AI-powered custom timelines and larger, easier-to-share group chats. The move says a lot about where the platform wants to go next – away from slower forum-style hangouts and toward feeds and real-time conversation that can be pushed harder, faster, and with less moderation pain.
The company’s pitch is simple enough. Communities brought people together around shared interests, but according to X, they attracted very little usage and plenty of spam, scams, and moderation overhead. That is usually code for ”expensive to run, hard to police, and not moving the numbers,” which is why the feature is being retired instead of redesigned.
AI-powered custom timelines replace Communities
On the feed side, X is rolling out Custom Timelines, which let users pin a topic directly to the home tab. The company says the feature supports more than 75 topics and is powered by Grok, which reads posts and sorts them by subject rather than depending on hashtags or keyword tricks that users have been gaming for years.
That is the more interesting part of the story. Topic feeds are not new, but AI classification gives X a cleaner way to package interest-based discovery without reviving a messy community layer. It also puts more of the platform’s identity in Grok’s hands, which is either a smart simplification or a very expensive way to reorganize the same old internet arguments.
XChat group chats get public joinable links
The second half of the plan is XChat, where group chats are getting public joinable links so people can be pulled in directly from the timeline. X says group chats can now support 350 members per chat, with that limit still growing, which makes the feature feel less like a side tool and more like a replacement for the old community container.
That direction tracks with what other platforms have been doing. Meta has spent years nudging conversations into private and semi-private spaces across its apps, while Discord has shown how sticky topic-based chat can be once people stop waiting for a forum reply. X is basically borrowing both models and hoping speed will do the rest.
What users lose and what X gains
For users, the trade-off is obvious: fewer fixed spaces, more fluid discovery. If you liked Communities because they acted like a modestly organized forum, that version of X is fading. If you prefer jumping from topic to topic or into a live chat from a shared link, the new setup is probably more useful.
For X, this is also a cleanup job. Communities created moderation headaches and did not scale in a way that justified the effort, so folding that behavior into AI feeds and group chats should be cheaper to run and easier to present as innovation. Whether it makes the platform feel more coherent or just more chaotic depends on how well Grok sorts the noise, and how quickly users decide they trust a machine to choose their conversation starters.
The bigger question is whether this becomes the new normal for X: less public structure, more algorithmic curation, and more chat as the default social unit. That may work nicely for engagement. It may also turn the app into a faster place to talk about things and a worse place to actually find them.
