# Brand sources

> Build your Rheos brand identity from website scrapes, AI imports of example posts and freeform documents so every generated post matches your tone of voice.

A brand's **sources** are the raw material Rheos uses to build (and keep refining) your **identity document** — the single markdown file Rheos reads before generating every post.

The richer your sources, the more on-brand the writing. Spending 10 minutes here pays off forever.

## The three source types

<Tabs>
  <Tab title="Website">
    Paste a URL and Rheos crawls the relevant pages — homepage, about, services, blog. It extracts tone of voice, themes, audiences, products, and unique phrases you tend to use.

    Use a website source when you have a public site that already reflects your brand. One scrape costs 20 credits.
  </Tab>

  <Tab title="AI import">
    Paste a handful of example posts (LinkedIn, Instagram captions, blog snippets) and Rheos reverse-engineers the voice. Best when your website is too corporate or doesn't exist yet, but you have content that sounds like you.

    Aim for 3–10 examples that represent the voice you want.
  </Tab>

  <Tab title="Documents">
    Upload a file you already have — a tone-of-voice guide, brand do's-and-don'ts, a
    glossary, taglines, customer personas, anything you'd hand a new copywriter. Rheos
    extracts the text and folds it into your identity document.

    Documents are powerful because they're deliberate: upload one covering the phrases you
    never want used and Rheos will steer clear of them.
  </Tab>
</Tabs>

## The identity document

All sources merge into a single **identity document** — a clean markdown summary of your brand. Open **Brands** from the sidebar and select your brand. The identity document is right there to read or edit if Rheos got something wrong.

<Tip>
  Treat the identity document like a living briefing. Re-read it every couple of months and tighten anything that's drifted.
</Tip>

## Re-syncing sources

Websites change, your voice evolves, you launch a new service. From the **Sources** tab you can:

* Re-scrape any website source (costs 20 credits each time)
* Re-import AI examples with fresh posts
* Upload a new or updated document

After any change, Rheos regenerates the identity document with version history — so you can roll back if something gets worse.

## What sources can't do

Sources teach Rheos **how** you sound, not **what's happening today**. For event-specific posts (a sale, a new hire, a product launch) put the news in the post prompt itself — that's the right place for it.

## Best practice

1. Start with a **website scrape** if you have one — it's the fastest win.
2. Add an **AI import** of 5 of your best posts to lock in voice.
3. Upload one **document** — a "Tone of voice" file with 5 do's and 5 don'ts works well.
4. Re-read the identity document and tighten anything that feels off.

Once your sources are dialled in, every future post starts 80% of the way to good.
