Twitter is adding new features to make it easier for users to watch and discover videos on its platform, the social network announced on Thursday. Most notably, the company is launching a scrollable TikTok-like scrollable video feed.

In the coming days, users on iOS will be able to click on a video in their feed to enter the new scrollable video feed. Once you finish watching the video you clicked on, you will be able to scroll up to start browsing more video content. You’ll then be in a scrollable feed of videos, which is similar to the browsing experience on TikTok. If you want to exit the viewer and go back to the original tweet, you can click the back arrow in the top left corner.
