Post one video to TikTok, Instagram and YouTube,
at the same time.

The short answer

ReelGenie doesn’t make or edit the video. You save one finished MP4 once, and saving never publishes it. Then you choose one TikTok, one Instagram and one YouTube account, set each platform’s options and approve once, at one time or a different time for each account. ReelGenie sends the same file to each account and shows each account’s own result. It posts only to TikTok, Instagram and YouTube, and the free plan of 30 posts a month counts the post once.

How to post one video to all three

1. Save the finished MP4 once

   Make the video with Claude or the tools you already use. Claude Code can upload the MP4 straight from your computer, Claude can hand over a finished HeyGen, Canva or Higgsfield download link, or you upload the file on ReelGenie’s Posts page. Add the caption, title and hashtags once. The post stays private until it is approved.

2. Choose the TikTok, Instagram and YouTube accounts

   Pick which of your connected accounts gets the video on each platform. ReelGenie never picks an account for you. Set the options each platform asks for: TikTok draft or Direct Post, Instagram Reel or Story, YouTube visibility and made for kids.

3. Approve once, at one time or one per account

   Post now, pick one date and time for all three, or give each account its next free posting time. Through Claude, each account can also have its own exact time. ReelGenie runs its checks first, so you see a caption that’s too long or a missing permission before anything is sent.

4. See each account’s result

   Each account gets its own row on the post: waiting to send, live, in the TikTok inbox, or failed with the platform’s reason. One account failing doesn’t stop the others.

Step-by-step guides: post to TikTok from Claude, post to Instagram from Claude and post YouTube Shorts from Claude.

What each platform gets

TikTok

• Most accounts get the video as a draft in the TikTok inbox (“In TikTok inbox”). You finish it in the TikTok app, add sound if you want, and tap Post.
• Direct Post appears only on accounts where TikTok has enabled it. Then you choose who can view the post from the options TikTok gives that account; there is no default. Comments, Duet and Stitch start off.
• The caption and hashtags together can be up to 2,200 characters.

Instagram

• The video goes to a connected Instagram professional account as a Reel, or as a Story if you choose that.
• A Reel also shows in the main feed unless you turn that off.
• Captions can be up to 2,200 characters with up to 30 hashtags.

YouTube

• The video is uploaded as public, unlisted or private. Public is the default.
• Made for kids: yes, no, or your channel’s default.
• Titles over 100 characters are shortened by YouTube, so ReelGenie warns you first. Descriptions can be up to 5,000 characters.

What ReelGenie checks before you approve

• One MP4 file up to 500 MB. A HeyGen, Canva or Higgsfield link can be an MP4 or MOV video up to 500 MB.
• The caption, title and hashtag limits above, for each platform you chose.
• For TikTok, a video frame rate between 23 and 60 frames per second, which TikTok requires.
• That each account is still connected and allowed to publish, and that Instagram can fetch the video.
• A warning when a sign-in won’t last until the posting time, or when YouTube’s or TikTok’s daily limits are used up.

ReelGenie doesn’t check the length or shape of the video, and it doesn’t resize it. TikTok, Instagram and YouTube each decide what they accept and whether a vertical video shows as a Short or a Reel.

One time or a different time for each account

• All at once: post now, or pick one date and time for every account.
• Next free posting time: each account goes at its own next free time from the posting times you set for it.
• Through Claude: Claude confirms the accounts and times with you, then each account can carry its own exact time.
• After approving: move one account to a new time on the Calendar, or cancel the accounts still waiting.

ReelGenie checks for due posts every minute, so Claude, your browser and your computer can all be closed. Read more about scheduling Claude posts without keeping Claude open.

Each account shows its own result

After approval, the post shows a row for each account with its own status: Waiting to send, Sending, Live, In TikTok inbox, In TikTok’s review, Failed with the platform’s reason, On hold, or Outcome unknown. If an account’s last 3 posts fail with the same error, its scheduled posts show On hold and nothing more is sent to it until you reconnect it or resend one. Scheduled isn’t posted, so check the row before you share a link.

Posting the same video again

• To an account you didn’t pick: once the first accounts have their results, use Publish to another account on the same post. An account that already got the post can’t be sent it again this way.
• As a new post: Duplicate as a new post makes a separate review copy with the same video and caption. No account or approval carries over, nothing is sent, and it counts as its own post when it goes out.

Questions about posting to TikTok, Instagram and YouTube

Does ReelGenie make or edit the video?

No. You, Claude or a video tool make the video, and ReelGenie posts the finished MP4. ReelGenie doesn’t generate, edit or resize video, and it doesn’t make posts from a web page address. The one kind of link it takes is a finished HeyGen, Canva or Higgsfield download link.

Can I upload one video to TikTok, Instagram and YouTube all at once?

Yes. Save the MP4 once, choose one TikTok, one Instagram and one YouTube account, and approve once. Each account then shows its own result.

It already uploads to YouTube. Can it post to TikTok and Instagram too?

Yes. Connect a TikTok account and an Instagram professional account in ReelGenie, then choose them with your YouTube channel when you approve. If the video has already gone to YouTube, use Publish to another account on the same post.

Does saving the video post it?

No. Saving makes a private post for review. Each delivery waits for approval: yours in ReelGenie, or Claude’s after it has confirmed the accounts and time with you.

Can each account post at a different time?

Yes. Give each account its next free posting time, ask Claude to set a time for each account, or move one account to a new time on the Calendar. It still counts as one post on your plan.

Will TikTok post it straight away?

For most accounts, TikTok gets it as a draft in the TikTok inbox, and you finish and post it in the TikTok app. Direct Post appears only on accounts where TikTok has enabled it, and then you choose who can view the post.

Is posting the same video on TikTok, Reels and Shorts a problem?

Each platform has its own rules about reused and unoriginal content, and posting through ReelGenie doesn’t change them. ReelGenie sends the exact file you saved and adds no watermark. It can’t promise views or reach.

How do I know each post went through?

Open the post in ReelGenie. Each account shows its own status, such as Live, In TikTok inbox or Failed with the reason, and a View live link when the platform gives one.

Is it free?

Yes. ReelGenie’s free plan includes 30 posts a month, 1 brand and 3 connected accounts, enough for one TikTok, one Instagram and one YouTube account. A post sent to all three counts once.
