The X API is an insanely powerful tool to find the most meaningful conversations on the platform.

To show what it can do, I put a sample app together as a small weekend project to highlight top ratios on X.

X is finally working on a solution for that frustrating moment when you refresh your feed and lose a video forever. According to a post from X’s product head Nikita Bier, a new Seen tab is likely on the way to help you revisit posts and clips you’ve already watched.
The potentially upcoming feature was teased when X user levelsio requested a history feature on iOS. Nikita replied with a screenshot showing a dedicated Seen tab sitting right next to the For You and Following feeds.
I’ve personally lost count of how many times a seemingly interesting post vanished into the digital void, so this feels like a massive win for usability.
The leaked UI looks incredibly clean, featuring the Seen label in the top navigation bar. It appears to function as a chronological history of your interactions, ensuring you can find that specific tweet or video without relying on the often-finicky search bar. This would be a major upgrade for a platform that has historically made it difficult to re-discover content once it scrolls past your eyes.
Interestingly, Nikita actually leaked two features at once. Observant users noticed a new floating bubble in the screenshot showing profile pictures of friends who have replied to a specific post. While the Seen tab is still in testing, some users like Brock Pierson claim they’ve already spotted this new reply indicator in their feeds over the last week.
Another X employee, Dan, confirmed he’s been using these “secret features” internally to avoid frustration. It’s a welcome change of pace, especially since we’ve recently seen some features disappear, like when X removed the ability to share posts directly to Instagram Stories on Android.
We’re also seeing more creative uses of the X API lately. Developer Mike Rosinsky recently launched X Ratios, a “weekend project” app that highlights the most controversial conversations and “dunks” happening on the platform. It’s a fun reminder of how powerful the platform’s data can be when put into the right hands.
If this rollout follows the usual pattern, we expect the Seen tab to start showing up gradually for some users before a wider release. But who knows, maybe X could flip the switch for everyone at the same time. We’ll be keeping a close eye on our own apps to see when that new tab finally sticks.
