How to post to TikTok and YouTube at the same time

TikTok and YouTube do not take quite the same post. TikTok stops text at 2,200 characters while YouTube allows 5,000.

TikTok vs YouTube: what's different

	TikTok	YouTube
Character cap	2,200	5,000
Images per post	4	4
Needs media	a video	a video
Long text becomes a thread	No	No
Comments inbox in fanout	No	Yes
Analytics in fanout	Yes	Yes

What fits both

Text: while both networks use the master draft, the counter holds you to the stricter cap, 2,200 characters (TikTok). Give YouTube its own tab to use its full 5,000.
Images: both take up to 4, so the same set goes to both.
Media: TikTok needs a video and YouTube needs a video. A text-only post is flagged for both. A video cannot be mixed with images in one post.
Over-limit text: neither network threads, so text over a cap is flagged on that network and has to be shortened.

Post to both in fanout

Connect TikTok and YouTube. Each login happens on the network's own permission screen.
Open the composer, write the master draft and select both accounts.
Check each tab. Both inherit the master text until you edit one; AI tailoring suggests a version for each, which you review before anything is published.
Attach media once. The same files go to both networks that accept them.
Publish now, or pick a date and time to schedule it to both.
