A brand’s brand document is what Rheos reads before it writes anything for that brand. Next to it sit the brand’s Voice — how it sounds — and, on a business brand, its ideal customers. All of it lives on the brand page itself. There is no separate Sources page any more.

Where it lives

Open Brand in the sidebar, then select the Business card. The brand page has these tabs:

Where it comes from

When you sign up, Rheos reads your website and whatever you tell it in the setup chat, and writes the first brand document from that. The meta line at the top of the document says which version you are on and what last changed it — you, the chat, or the setup interview. Your website address sits in Basics on the Business tab. The pencil on that card lets you change it, along with your industry, location and founding year.

Changing the brand document

You have three ways to change it, and they all end in the same document.
  • Edit it yourself. The document is a normal editor. Type, paste and delete as you would anywhere. Rheos saves as you go.
  • Comment on part of it. Select some text and a comment button appears. Say what you want changed — “make this warmer”, “we don’t do weddings any more” — and Rheos rewrites just that passage. You see the change before you keep or reject it.
  • Ask the brand chat. The chat icon in the top bar opens the brand chat. Tell it what’s new about the business and it proposes edits to the document for you to approve.
Once your brand is set up, Rheos never rewrites the brand document on its own.
History, the clock in the top bar of a business brand, lists every change to the brand. Undo an individual edit, or filter to Doc versions and Restore an earlier version of the document.

Your voice

The Voice tab is one document, written as prose. What you write there shapes the very first draft Rheos writes for a post, not just later edits. If Rheos sounds wrong, fix it here — say what the brand sounds like and what it never says. If you give your social handles when you sign up, Rheos uses them to start the Voice document for you.

Ideal customers

The ICP tab lists the brand’s Ideal customers. Add one and Rheos works out where they make decisions, platform by platform. Where Rheos couldn’t find specific evidence for a platform, it says so — treat that one as a guess until you confirm it.

What the brand can’t do

The brand teaches Rheos how you sound, not what’s happening today. For event-specific posts — a sale, a new hire, a product launch — tell Rheos about it when you start the post. That’s the right place for it.

Best practice

1

Check your website in Basics

It’s the fastest win if you have a site.
2

Read the brand document and fix it

Correct anything Rheos got wrong by editing it or commenting on it. Your edits stick — the document is only rewritten when you ask for it.
3

Fill in your voice

A few honest sentences on the Voice tab change every first draft that follows.
