Remember the last time you opened X and felt like you were drowning in content you never asked for? Politics when you wanted tech news. Celebrity drama when you were just trying to catch up on cricket scores. Sound familiar? Well, X just dropped something that might actually fix that — and honestly, it’s one of those features you’ll wonder how you lived without.
It’s called Custom Timelines, and it rolled out on April 21, 2026. Think of it like building your own little TV channel lineup, except instead of channels, you’re picking the topics you actually care about.
So how does it actually work?
Picture this: you open X on your phone, and right next to the “Following” tab, there’s a small “Add+” button sitting quietly. Tap it, and a whole menu of topics opens up — over 75 of them. We’re talking everything from Machine Learning and Cryptocurrency to K-pop, Vintage Cars, and Urban Planning. You pick the ones that matter to you, pin them, and boom — they show up as swipeable tabs right on your home screen.
You can pin up to 10 of these custom feeds. So maybe your lineup looks like: Technology, Cricket, Finance, Anime, and Fitness. Every time you open the app, those feeds are waiting for you, already loaded with relevant posts. No more hunting, no more scrolling through noise.
Here’s where it gets genuinely interesting — the AI behind it
X didn’t just slap a filter on some keyword search and call it a day. The whole thing runs on Grok 4.1, their in-house AI. And the smart part? It doesn’t just look for posts containing the word “cricket.” It actually understands what a post is about — even if nobody used the obvious words. It reads context, picks up on meaning, and figures out whether a post actually belongs in your feed.
It also watches how you interact. Lingering on a post for a few seconds, hitting repost, leaving a like — all of that quietly teaches the feed what you want more of. Over time, your timelines get sharper and more dialled-in. Early data suggests people are spending about 28% more time on these feeds compared to the old Lists feature, which tells you the AI is doing something right.
What about all that stuff you DON’T want to see?
X thought of that too. Alongside Custom Timelines, they launched something called Snooze Topics. Say you’re exhausted by election coverage or you just don’t want to see sports highlights for a day — you can hit snooze on that topic for 24, 48, or 72 hours, or even mute it indefinitely. It works on your main “For You” feed, giving you a bit of breathing room without permanently cutting anything off.
Think of Snooze Topics as the volume knob for your feed. Custom Timelines puts you in the driver’s seat; Snooze Topics keeps the backseat noise down.
Who can actually use this, and how do you get in?
Right now, it’s a Premium-only feature — covering all three tiers: Basic at $3/month, Premium at $8, and Premium+ at $16. If you’re on iOS or using X on a browser, you already have access. Android users got server-side access from April 23 onward, meaning no app update needed — it just appears.
Free users can peek at what these timelines look like but can’t pin anything. Classic “try before you buy” move.
Is it actually worth getting excited about?
Here’s the honest take: this feels like the feature X should have built years ago. The old Communities feature was quietly fading — engagement had dropped nearly 45% — and this looks like X’s answer to that problem. Instead of group spaces, they’re giving you personalized content rivers you can actually control.
It’s not perfect yet. You can’t build a completely custom topic from scratch — you’re choosing from X’s curated list. But with 75+ options and feeds that evolve with your habits, most people will find something that works.
If your current X experience feels messy and overwhelming, Custom Timelines is genuinely worth trying. Your feed should work for you — and this is the closest X has come to making that actually happen.
