# Brand Profile and Knowledge

Every brand in Postbird has a **brand profile**: what the business does, who it is for, how it talks, and the facts it can stand behind. Everything the AI writes or makes for that brand follows it: **Write with AI** drafts, **Hashtags** suggestions, **Make an image**, and the inbox's suggested replies to comments. Two brands in one account each keep their own voice.

Open it from **Settings**, **Brand profile** (for the brand picked at the top), from the brand switcher, **Brand profile**, or from a brand's edit window.

## Fill it from your website

1. Under **Fill from website**, paste the brand's website, for example `yourbrand.com`.
2. Click **Fill from website**. The AI reads the page and fills in the fields below: what the business does, who it is for, the tone, the language, a call to action, links and the image style.
3. Check every field and change what is off. Nothing is saved yet.
4. Leave **Also add ... to the knowledge** ticked to keep the page's text as knowledge.
5. Click **Save profile**.

Filling from a website costs the same as one round of AI drafts (**0.25 credits**), and nothing if the page cannot be read. If your account uses its own AI key, it runs on that key instead.

## Voice

- **What the business does** and **Who it is for**: a few plain sentences. The AI stays on topic and writes for these people.
- **Tone of voice**: pick one or more, such as Friendly, Professional or Playful, and add anything else under **More about the voice**. A tone you pick in **Write with AI** wins for that one post.
- **Languages**: the languages the brand posts in. The first is the default; ask for another language in the brief and the AI writes in that one.
- **Emoji**: None, Some or Lots. **No preference** leaves it to what is usual on each network.
- **Call to action**: what you usually ask readers to do at the end of a post.
- **Your links**: links the AI may put in posts. It never makes up other links.

Sad or serious posts (a condolence, an apology, an outage) always stay plain: no emoji, no hashtags and no sales call to action, whatever the profile says.

## Words and hashtags

- **Words and phrases to use**: words that sound like the brand.
- **Words to never use**: the AI leaves these out.
- **Hashtags in posts**: None, A few or Many.
- **Hashtags to always add**: for example your brand tag. **Hashtags** suggestions put them first on networks that use hashtags.
- **Hashtags to never use**: never suggested and never added.

Press Enter after each word, language or hashtag.

## Image style

**Brand colours** (colour codes such as `#2f6df2`), **Mood**, **Style** and **Never show** are used every time you click **Make an image** for this brand.

Click **Save profile** at the bottom when you are done. The next AI draft, hashtag suggestion or image uses it.

## Knowledge

Knowledge is the facts the AI may state in posts and replies: prices, products, offers, opening hours, answers to common questions. For each post it uses the facts that fit, and it never contradicts them. A post about something else gets none of them.

- **Add a fact**: type a title and the fact, offer or answer, then click **Add**.
- **Add a web page**: paste a page address, for example your pricing page. Postbird reads the text on it.
- **Add a file**: a PDF, Word, text, CSV or spreadsheet file. Postbird reads the text in it.

Click the pencil next to a typed fact to change it, or the bin to remove any entry. Adding pages and files is free.

## With the API or an AI assistant

Your AI assistant can set a brand up too: `get_brand_profile`, `update_brand_profile`, `fill_brand_profile`, `add_brand_knowledge` and `delete_brand_knowledge` are in the API and on the MCP address. See [API keys and AI assistants](api-and-mcp.md).
