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.Documentation Index

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
Tailor a post
Switch tabs per network
A tab appears for each selected platform. Click a tab to see that network’s preview.
Edit just that platform
Changes you make inside a platform tab only affect that one. The shared draft stays untouched.
Character limits
Rheos warns you when a platform’s copy is over its character limit before you publish. Common limits:| Platform | Limit |
|---|---|
| X | 280 characters |
| Bluesky | 300 characters |
| Mastodon | 500 characters |
| 3,000 characters | |
| 2,200 characters | |
| ~63,000 characters |
