Is the same file posted everywhere?

The same video, adjusted per platform for aspect ratio, caption format and hashtag conventions. What differs more than the file is what each platform rewards, so identical uploads legitimately perform differently.

Which platforms are supported?

TikTok, Instagram Reels, YouTube Shorts and LinkedIn. You can connect multiple accounts on each.

Does cross-posting hurt reach?

Posting the same video to different platforms is normal and not penalised. What can hurt is visible competitor watermarks, which is a reason to publish from a single source rather than downloading from one platform and re-uploading to another.

Can I schedule different times per platform?

Yes. Optimal posting times differ by platform and by audience timezone, and the schedule is set per destination rather than globally.
