How to Post One AI Video to TikTok, YouTube Shorts, Instagram Reels, Facebook and X in One Click

Every AI video tool stops at the download. You generate a clip, save it, and then the real work starts: open TikTok, upload, write a caption, open YouTube, upload again, write a title, open Instagram, and so on. Five uploads for one video, every day. We build ReelMint because we were tired of that, and this post walks through how the one-click version works, including the parts that are easy to get wrong.

Step 1: connect each platform once

Go to Connections and press Connect next to YouTube, TikTok, Instagram, Facebook or X. Each one opens the platform's own sign-in page. You approve a publishing permission there, and you are sent back. ReelMint never sees your password; the platform gives it a token to post on your behalf, and you can revoke it from the platform's settings at any time.

Two details that trip people up:

  • Instagram posts through its Facebook Page. Your Instagram account has to be a professional account linked to a Facebook Page. That is Meta's rule for any app that publishes to Instagram, not ours.
  • TikTok asks for an extra permission to post directly. Approve it when the screen shows it, or every share will land in your TikTok inbox as a draft instead of publishing.

The connect-your-channels guide has a screenshot of each screen.

Step 2: open any video and press Share

Every video in your library has a Share button. It opens a sheet with one tab per connected destination. Pick the ones you want. Each tab holds its own caption, title and hashtags, because the platforms want different things: YouTube wants a title and a description, TikTok wants a short caption with hashtags inline, X wants under 280 characters, and Instagram likes a longer caption with the hashtags at the end.

You can write all of them by hand, or press the AI button once and it writes every version in each platform's own idiom and within its limits.

Step 3: publish now or schedule to the minute

Publish sends it everywhere at once. Schedule lets you set a time per destination, so the Short goes out at 9 am and the Reel at 6 pm. The scheduled list shows every pending post grouped by day, and a failed post says why in plain words (the most common reason is an expired platform token, which a Reconnect fixes).

What about the AI video itself?

The clip can come from anywhere. Upload one you made elsewhere, or generate it in the studio from text, an image, or a reference clip, with the price printed on the button before you click. New accounts can also claim 27 finished example videos for free, with no card, which is the fastest way to test the whole loop: claim a clip, connect one channel, post it.

Posting on a schedule without touching it

If you want the same thing every day, Bot Studio turns the recipe into a standing job: it generates a new video on a schedule and posts it to the channels you picked, with the monthly cost shown before you save it. We wrote a separate post about that, and the autopilot page explains it in two minutes.

Limits you should know

  • YouTube allows roughly a dozen uploads a day through an app before it asks for a break.
  • Facebook and Instagram share a rate limit per account; a bot posting hourly to both will hit it.
  • X counts links and media against the character limit in its own way, so a caption that fits on paper can still be refused. The sheet shows the real count.

The whole thing in two minutes

Minty, the assistant in the product, made a one-minute video on exactly this: How to connect channels and auto-post. If you prefer reading, the publish page has the steps and a few questions people ask before they connect anything.
