How to post one video to TikTok, YouTube, Instagram and 7 more networks at once
Cross-post a video to TikTok, YouTube, Instagram, LinkedIn, Threads, Facebook, Bluesky, Pinterest, Google Business and X from one upload with Eurekuh, a social media scheduler priced per workspace.
Posting the same video everywhere usually means logging into each network, uploading it again, rewriting the caption to fit and remembering to post at the right time. Eurekuh turns that into one composer and one upload: write once, upload once, schedule once, then publish to every network you are on.
The ten networks Eurekuh publishes to
Eurekuh publishes natively through each network’s official API to:
- TikTok
- YouTube
- Threads
- Bluesky
- Google Business Profile
- X
Eurekuh is upfront about the exceptions: Google Business publishing is waiting on Google’s API quota approval, Pinterest does not support video pins on its current access level, and X charges per post.
Step by step: cross-post a video
- Connect your accounts (sign in with Google or an emailed code; no password is stored).
- Upload the video once. MP4, MOV and WebM are supported, along with photo and text posts.
- Write the caption, then adjust it per platform. Every network has its own limit: X allows 280 characters, Bluesky 300, Threads 500, TikTok and Instagram 2,200, LinkedIn 3,000 and YouTube 5,000.
- Set per-platform privacy and pick a time, or publish now.
- Eurekuh posts on schedule and collects views, likes and engagement in one analytics view.
Eurekuh keeps an up-to-date reference of social media character limits and image sizes for every network.
Also included
- A calendar feed you can subscribe to, so scheduled posts show up next to your meetings.
- A link-in-bio page at eurekuh.com/your-handle.
- An MCP server, free on every plan, so AI assistants like Claude can schedule posts for you.
Pricing: per workspace, not per channel
Most schedulers charge per connected channel, which gets expensive fast when you post everywhere. Eurekuh prices per workspace. There is a free plan with 2 accounts and 15 posts a month on every platform except X, with no card needed. Creator is €9.99 a month for 8 accounts and unlimited posts, and Business is €29 a month for 25 accounts. See Eurekuh pricing for the current plans.
