Cross-Posting Guide
Post to Threads and X from one composer
Threads first, X second. One workflow ships your post to both platforms in seconds.
Quick answer: To post to Threads and X at the same time, use Socialync. Upload your video once, pick Threads and X, write a caption for each, then post now or schedule it. Both go live at the same moment. Posts you make in the Threads app stay on Threads, so post from Socialync when you want both. X is on paid plans, from $20 a month.

Why Socialync for Threads to X
Upload once, post to both
Drop a video into Socialync. We publish to Threads and X at the same time, so you post to X and Threads simultaneously without copy-paste.
Lead with the image on Threads
Plain text Threads underperforms in 2026. Image attached posts consistently get materially more reach in our testing.
Trim for X
X caps at 280 (free) or 4k (Basic, Premium, or Premium+). Compress the Threads version into a punchy tweet.

The multi-platform posting is seamless. My content reaches 3x more people with zero extra effort.

Simple dashboard, easy sign-up, and the scheduling is so nice. If I make 10 videos in one day I can schedule them to all platforms weeks in advance. Goated!

I built this because I was burning out posting manually. Now I post in 3 minutes instead of 45.

How it works for Threads to X
Five steps. One upload. Posts to both platforms.
- Write your Threads draft

Frequently asked questions
Can I post to Threads and X at the same time?
Yes. Socialync publishes to both simultaneously with separate caption fields.
Why post to both Threads and X?
Different audiences. Threads is more visual and curated; X is more news driven and faster. Posting to both doubles your reach for the same writing effort.
Will posts I make in the Threads app copy over to X?
No. Socialync publishes what you make in Socialync. It can't see posts made in the Threads app, including ones already up. Make the post in Socialync, pick Threads and X, and it goes to both at once. To bring over something already on Threads, upload the original file to Socialync and pick only X.
