Upload once.
Post everywhere.
Post Once publishes your short video to Instagram Reels and YouTube Shorts and TikTok from one place. You can also do it by asking Claude.
Get Post Once1. Connect your accounts
Sign in with Instagram and Google and TikTok. You approve exactly what Post Once may do and you can disconnect at any time.
2. Upload your video
Add a title and description and hashtags yourself or let AI suggest them. Nothing posts until you press Post.
3. Post to every platform
Pick where it goes. Choose a trial reel for Instagram and privacy settings for TikTok. See the live links in one list.
How Post Once uses your accounts
Post Once only uploads videos that you choose to publish and only when you press Post or ask Claude to post. It reads your account name and profile picture so you can see which account you are posting to. It does not read your messages or followers or analytics. It never posts on its own. Read the Privacy Policy for full details.
Works inside Claude
Every account comes with a private Claude connector link. Add it to Claude and say "post my latest video everywhere". Claude asks if you want a trial reel and whether you want it to write the caption and hashtags before anything goes live.
