Sign up
Head to dashboard.rheos.app and create an account with Google or email. You’ll start on the Free plan with 400 credits a month — enough to try every feature.
Set up your first brand
During onboarding you’ll create a Personal brand (you, the human) or a Business brand (your company). Add a name, then point Rheos at either your website or a few example posts. Rheos scrapes that content to build your brand identity — the tone, themes, and audiences it will use for every future post.
Connect a social account
Open Settings → Connections and connect at least one platform. Instagram and LinkedIn are the most common starting points. You can also schedule posts before connecting and publish manually.
Create a post
Click New post in the sidebar. Pick a content type (text, image, carousel or video), type a one-line prompt — “5 myths about pension transfers”, say — and Rheos will suggest 5 post angles built from its formula tree (Intent → Hook → CTA). Pick one and the Unified Post Editor opens with a full draft.
Refine it
Highlight any line to leave a comment (“make this punchier”, “shorten by half”) — Rheos rewrites just that part. Swap the image in the embedded Image Studio. Tweak the formula chips at the top to change the angle without starting over.
What to do next
Build out your brand identity
Add more sources — extra documents, ad examples, additional websites — so Rheos sounds even more like you.
Learn the formula system
Understand Intent, Hook and CTA so you can steer Rheos to the exact angle you want.
