The flow
1
Answer a few questions
Select New post. Rheos asks where the post is going and a few short questions about it.
2
Pick an angle
Rheos offers a few angles. Pick one and it writes the first draft — or select Write manually to skip the AI and write it yourself.
3
Edit
The Unified Post Editor opens with the copy written. Ask the chat for changes, add hashtags, and attach or generate a visual.
4
Publish or schedule
Post now or Schedule.
One platform per post
Each post goes to one platform: LinkedIn, Meta or X. Meta counts as one platform and covers Instagram and Facebook together, so a Meta post can go out to both. To say the same thing on LinkedIn and X, write a post for each. Which LinkedIn account a post goes to follows the brand: a personal brand posts to your profile, a business brand to its company page.Copy and media
A post starts as copy. The Attachments card under the post gives you two routes to a visual:- Attach — upload one, or pick something you have already saved to your Library.
- Generate — make an AI image in the Image Studio.
Instagram cannot publish a text-only post. If a Meta post includes Instagram and has nothing attached, Rheos blocks Schedule and Post now until you add an image or video.
What each platform accepts
When Rheos publishes, character limits follow the connected account, so an X Premium account can take the longer limit — though the editor still holds X posts to 280 for now. Rheos warns you before you publish if the copy is over. See per-platform variations.
