Post HeyGen and Canva videos from Claude,
after you watch and approve them.

The short answer

ReelGenie doesn’t make the video. HeyGen or Canva makes it, and Claude gives ReelGenie the finished video’s download link. ReelGenie downloads the video, checks it and saves it as a private post with a phone preview and the caption. Saving a post never publishes it. Nothing goes to TikTok, Instagram or YouTube until you approve the accounts and the time, now or later. The free plan covers 30 posts a month.

How to post a HeyGen or Canva video from Claude

1. Make the video in HeyGen or Canva

   Ask Claude to make it with the HeyGen or Canva connector, or make it in HeyGen or Canva yourself. ReelGenie sends the file as it is, so choose a vertical 9:16 size (for example 1080 × 1920) before the video is rendered or exported.

2. Let Claude save it to ReelGenie for review

   Claude passes the download link HeyGen or Canva returned to ReelGenie. ReelGenie downloads the video, checks it and saves a private post, and Claude gives you a review link. Claude Code and Codex can also upload an MP4 straight from your computer.

3. Watch it and approve the accounts and time

   Play the video in the phone frame, change the caption in the chat or in ReelGenie, and pick the TikTok, Instagram or YouTube accounts and whether it goes now or at a set time. Claude asks you rather than choosing, and nothing is sent before approval.

4. Check what each platform did

   Each account shows its own result. Most TikTok accounts get the video as a draft in the TikTok inbox (Draft ready): open TikTok and post it. Instagram receives it as a Reel on a professional account. YouTube receives it as public, unlisted or private, as you chose. A failed send shows the platform’s reason in plain words.

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

HeyGen and Canva make the video. Who posts it?

Most “HeyGen Claude” tutorials end when the avatar video is ready. HeyGen’s own guide to its Claude connector ends with the video in your HeyGen projects, ready to download. Canva can share designs to TikTok Ads, Instagram and YouTube, but its share list doesn’t include ordinary TikTok posts. So the last step is usually a download, a phone and a manual upload for each account.

ReelGenie picks up from there. Claude saves the finished video by link, you watch it and approve where and when it goes, and ReelGenie sends it and reports what each platform did. You don’t need to download the file or move it to your phone.

If you want a tool that writes and makes the video for you, HeyGen or Canva is that tool; ReelGenie only posts what they made. See how ReelGenie compares with Blotato, Postiz and others.

Which links ReelGenie accepts

• HeyGen video links on files.heygen.ai, Canva export links on export-download.canva.com and finished Higgsfield videos on d8j0ntlcm91z4.cloudfront.net. Other hosts are refused, including redirects to other hosts.
• https:// links only, to an MP4 or MOV video up to 500 MB that downloads within 5 minutes.
• The checked video is the one you review and the one each platform receives. A link that fails leaves no half-saved post behind.
• These links expire: Canva’s after about 24 hours, HeyGen’s at the time set in the link. If ReelGenie says a link expired, ask Claude for a fresh one.
• Made the video somewhere else? Download the MP4 and let Claude Code or Codex upload it from your computer, or upload it on ReelGenie’s Posts page.

Questions about posting HeyGen and Canva videos

Does ReelGenie make the video?

No. HeyGen, Canva or another video tool makes the video, and Claude saves it to ReelGenie. ReelGenie doesn’t generate or edit video. Claude can write the script and the caption.

Can Claude post a HeyGen video to TikTok?

Not on its own. Connected to ReelGenie, Claude saves the HeyGen video for your review, and after you approve, ReelGenie sends it to TikTok. Most accounts get it as a draft in the TikTok inbox, which you post from the TikTok app. Direct Post appears only on accounts where TikTok has enabled it. See how to post to TikTok from Claude.

Can I post a Canva video to TikTok?

Canva’s own sharing covers TikTok Ads, not ordinary TikTok posts. With ReelGenie, Claude exports the video from Canva and saves the export link for your review; after you approve, ReelGenie sends it to your TikTok account.

Does saving the video publish 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.

Which video links work?

Links on files.heygen.ai (HeyGen), export-download.canva.com (Canva exports) and d8j0ntlcm91z4.cloudfront.net (finished Higgsfield videos), over https://, to an MP4 or MOV up to 500 MB. ReelGenie saves a Higgsfield video by its link the same way; Higgsfield makes the video, not ReelGenie. For any other tool, download the file and upload it instead.

What if the link has expired?

Ask Claude to get a fresh link from HeyGen or Canva and save it again. Canva export links last about 24 hours.

Can it mark the video as AI-generated?

For TikTok Direct Post, you can turn on TikTok’s AI-generated label before you approve. ReelGenie doesn’t set an AI label for TikTok inbox drafts, Instagram or YouTube; add it in TikTok, Instagram or YouTube Studio when it applies.

Does it work with Codex or Claude Code?

Yes. Any agent connected to ReelGenie can save a HeyGen or Canva link the same way, and Claude Code and Codex can also upload an MP4 from your computer.

Is it free?

ReelGenie’s free plan includes 30 posts a month, 1 brand and 3 connected accounts, with no time limit. A video sent to TikTok, Instagram and YouTube counts as one post. Your Claude, HeyGen and Canva plans are separate.

Can I try it before signing up?

Yes. Try ReelGenie without signing up to see the review and approval steps.
