Repostit

Download the video, remove the TikTok logo, change the size, copy the caption, upload it again. Then start over for the next app, because posting one short video on several social apps means the same chores for each of them. Repostit picks up each new TikTok and posts it from your own accounts to up to seven other apps. Each copy goes out without the watermark and in that app's format, for example a Reel on Instagram.

You set up routes, each from one source account to one destination. A route for new posts sends every video as soon as it is live on TikTok. A route for older posts sends your back catalog at once or a few videos a day. Each route can start with a manual check of every post and later switch to automatic. Photo posts and carousels travel the same way, slides in order.

The homepage says more than 10,000 creators use Repostit and over 5 million videos have been reposted. Around the reposting, the dashboard has a calendar for planning posts, with a preview of how one post looks on each app. A clip tool cuts a long YouTube video into short vertical clips and gives each clip a score. Backups copy your videos into your own Google Drive or Dropbox.
