For creators, businesses, and others who already post on social media, Post Once reduces the work of sharing the same content across accounts and keeping a backup. Post from your chosen source account in its usual app, and Post Once automatically reposts new photos and videos, with their captions, to connected accounts on Instagram, YouTube, Facebook Pages, Threads, X, and LinkedIn. It’s designed for people who prefer posting directly in a social app rather than composing and scheduling posts in a separate tool. Post Once can also save your posts and captions to cloud storage you control, including Google Drive, Dropbox, Backblaze B2, and Amazon S3 or compatible storage. This can help keep an archive of content—including Stories—if you leave a platform or lose access to an account. The service works with Instagram, YouTube, Facebook, Threads, and X as source accounts; which destinations receive a repost depends on the connected accounts and platform support.
