X is making one of its biggest structural changes in years, and it’s not subtle. A core feature is getting shut down, but in its place, the platform is doubling down on AI-driven feeds and real-time chats.
Why is X shutting down Communities?
X has confirmed that it is closing its Communities feature, which originally launched as a way for users to gather around shared interests, similar to forums or subreddits. The reason is pretty blunt: low usage and high maintenance.
Despite the idea sounding great on paper, Communities were used by less than 0.4% of users, while also becoming a hotspot for spam, scams, and moderation headaches. 
In other words, it was a feature that demanded a lot of effort without delivering enough value. So X is cutting it loose.
What is replacing Communities on X?
Instead of Communities, X is splitting that experience into two very different directions: custom timelines powered by AI and expanded group chats.
On one side, there are Custom Timelines, which let users pin topic-based feeds directly to their home screen. These feeds are powered by Grok, X’s AI system, which actually reads posts and categorizes them instead of relying on hashtags or keywords.
On the other side, X is pushing heavily into group chats via XChat. These chats now support joinable public links, making it easier to bring people into conversations instantly. Group sizes are also expanding, with limits expected to grow well beyond the current few hundred users.
What does this shift actually mean for users?
This is less about removing Communities and more about redefining them. Instead of fixed groups, users will now follow topics through AI-driven feeds or jump into real-time conversations via group chats, shifting away from slower, forum-style interactions.
It also signals a bigger strategy shift. X is betting on AI and messaging as the future, simplifying the experience while moving toward faster, more dynamic ways of connecting.
