One post rarely lands the same on LinkedIn as it does on Instagram or X. Rheos lets you start from a single draft and tweak it per network — without having to create separate posts.

​
How variations work

When you build a post, you pick which platforms it should go to. Each one starts with the same copy and media. From there, you can override:
  • Caption / body text — shorten for X, lengthen for LinkedIn, add line breaks for Instagram
  • Hashtags — different sets per platform
  • Media — swap an image, change the order of carousel slides, or use a different aspect ratio
  • Link — some networks let you include a URL in the body; others (Instagram) don’t
Don’t have time to tailor each network? Just publish the shared draft — Rheos will adapt media to each platform’s required aspect ratio automatically.

​
Tailor a post

1

Pick your platforms

In the publish panel, tick every network you want this post to go to.
2

Switch tabs per network

A tab appears for each selected platform. Select a tab to see that network’s preview.
3

Edit just that platform

Changes you make inside a platform tab only affect that one. The shared draft stays untouched.
4

Publish or schedule

When you’re happy with each preview, hit publish or schedule. Each network sends its tailored version.

​
Character limits

Rheos warns you when a platform’s copy is over its character limit before you publish. Common limits:
PlatformLimit
X280 characters
Bluesky300 characters
Mastodon500 characters
LinkedIn3,000 characters
Instagram2,200 characters
Facebook~63,000 characters
LinkedIn supports company and person mentions inside the body — type @ and pick from the dropdown.
If you delete a platform from the post after writing a variation, that variation is discarded. Re-add the platform and it’ll start from the shared draft again.
Email support@rheos.app if anything looks off.
