# Brand knowledge base

> Give the AI the source material it needs to write in your real voice: editable documents and uploaded files, per brand.

Every brand has its own knowledge base, a place to keep the source material the AI uses to write on-voice content. It is **free** on all plans.

## Open the knowledge base

Click any brand card to open it, then switch to the **Knowledge Base** tab.

## What you can store

* **Editable documents** in a Notion-style editor. Write FAQs, your brand story, positioning, service descriptions, tone guides, and offer details. Use headings, lists, code blocks, dividers, links, and quotes.
* **File uploads.** Markdown (`.md`), plain text (`.txt`), and Word (`.docx`) files are converted to editable documents automatically. Images and PDFs are stored as assets.

## Limits

These are the same on every plan:

* Up to **20 items** per brand
* Up to **25 MB** per file

## Add a document

<Steps>
  <Step title="New document">
    On the Knowledge Base tab, click **New document** and give it a title.
  </Step>

  <Step title="Write">
    Use the editor to add your content. It auto-saves as you type, and a "Saved"
    indicator confirms when it is stored.
  </Step>

  <Step title="Navigate">
    Click any heading in the side rail to jump to that section.
  </Step>
</Steps>

## Upload a file

Click **Upload file** or drag files in. Markdown, text, and Word files become editable documents. Images and PDFs are kept as assets. Hover any item to rename or delete it.

<Tip>
  The richer your knowledge base, the more your generated content sounds like
  you. A brand with no documents still works, but adding a few pages noticeably
  improves relevance.
