yellit — publish one video to TikTok, Instagram, YouTube and X
Upload a video once and yellit publishes it to your own TikTok, Instagram, YouTube, and X accounts in a single action, instead of uploading the same file four times by hand. Each platform reports back separately, so a failure on one is never hidden behind a success on another.
How it works
- Connect an account. Authorise each one on the platform's own consent screen. yellit never sees your password — only a token, which you can revoke from the platform or from yellit at any time.
- Choose what to post. Pick a video or image, write a caption, add a title, and choose who can see it. Tick the destinations you want.
- Publish. Each destination reports its own result, with a link to the post it created.
What you can post
One video to TikTok. An image, a carousel of 2–10, or a Reel to Instagram. A video or a Short to YouTube. Text, up to four images, or one video to X. You choose who can see each post before it goes out, and yellit only offers the visibility levels your account is actually permitted to use.
The platforms disagree about the details — where your media has to live, what counts as unlisted, what a caption limit is — and those differences are enforced before a publish starts rather than halfway through. What each platform accepts.
What it does not do
yellit publishes. It has no scheduler, no queue, and no analytics; it never posts on a timer, and it never reads your existing posts, comments, messages, followers, or insights. Nothing is published without an action you took — clicking Publish, or running a command you typed.
It does not edit your video, add watermarks, or change your caption beyond trimming it to a platform's length limit. What you upload is what gets posted.
The permissions it asks each platform for follow from that: one to read the name of the account you connected, one to publish, and nothing else. Permissions we request.
From the command line
The same publish, for anyone who would rather not leave the terminal. It signs in with a token you create in your account and talks to this same service, so the accounts you connect here are the ones it posts to.

Tokens are encrypted at rest and used only to publish what you ask for. Media is deleted from our storage as soon as the platforms have taken it. See the privacy policy, or delete your data at any time.
