⚠️Repost: This is one specific option inside the Share menu (usually a yellow button with circling arrows). It shares the video natively on TikTok by pushing it to your followers' or mutual friends' For You Page (FYP/feed). ⚠️Key characteristics (as of late 2025): The reposted video credits the original creator (their username is prominently shown). It doesn't appear as a post on your main profile grid by default (though recent updates allow optional visibility in a Reposts tab, feed, or even grid if enabled). It's designed to amplify content you like, support creators, and boost algorithm visibility without creating new content. You can add a short comment/caption (like a quote tweet). It's undoable by going back to the video > Share > Remove Repost. ⚠️Repost is similar to retweeting on X (Twitter) or resharing on other platforms, but focused on TikTok's recommendation algorithm. ⚠️In short: Share is the overall button/menu for all sharing methods, while Repost is the TikTok-specific way to publicly boost/share a video to your network inside the app. If you're seeing "Repost" as a button, it's always accessed via the Share arrow first.
