How it works — AurumPublish

Connect your accounts Sign in to each platform through its official sign-in screen and allow the permissions needed to publish for you. You can disconnect any platform at any time.
Add your vertical video Drop in one 9:16 file. AurumPublish reads its length and dimensions and prepares a copy for any platform that needs one.
Write your caption and first comment One description for all platforms, plus an optional first comment to pin under the post.
Review and publish Check where the video will go, then publish. Each platform reports its own result, and you see it next to the post.

The TikTok review screen

TikTok asks for a clear confirmation before a video is published on your behalf. AurumPublish shows it for every TikTok post.

The line "Posting to your nickname (@username)" shows which TikTok account will receive the video.

You choose the privacy level. Only the options TikTok allows for your account are offered, and nothing is selected for you.

Allow Comment, Duet and Stitch are switches you set yourself, as TikTok requires.

You can mark promotional content or a paid partnership, and you confirm TikTok's Music Usage Confirmation before the post goes out.
