Post once on Instagram.
Auto-republish everywhere.
You post a Reel. Crossposter detects it, fetches the video, and republishes it to TikTok and YouTube Shorts on your behalf — with your caption, on your schedule, no manual re-upload tax.
The Flow
Source
You keep posting Reels exactly the way you do today. No new app, no new editor, no new behavior.
Destination
TikTok
Direct-posted to your account with the caption you set.
Destination
YouTube Shorts
Uploaded as a Short, public or unlisted — your call.
How It Works
01
Authorize Crossposter on Instagram, TikTok, and YouTube. Standard OAuth — we never see your password, and you can disconnect anytime.
02
Open Instagram. Post your Reel. That's it on your end. No new app to learn, no extra step, no new editor.
03
Crossposter detects the new Reel within minutes, downloads the video, and republishes it to TikTok and YouTube Shorts with your caption.
Why we built it
Cross-posting is a tax on creators. The same 30-second video gets re-uploaded three times a week, with three slightly different caption tweaks, in three different apps. Every minute of that is friction between you and the next thing you want to make.
Schedulers help, but they all want you to upload to them first. Crossposter inverts it: you post where you already post — Instagram — and your video shows up everywhere else automatically.
Built by Cyber Goose in San Francisco.
